You don't want me. You're all hard work and deadlines! I'm... snowballs and fun times.
—Jack, to the other Guardians
Jackson Overland Frost, better known as Jack Frost, is the main protagonist in Rise of the Guardians and an immortal supernatural being much like the Guardians. Unlike the others, however, he is a loner, the classic rebel without a cause, sarcastic and mischievous. As the manifestation of winter, Jack Frost is capable of manipulating ice and snow. He is the spirit of mischief and chaos personified, but when he discovers the purpose behind his powers, he will become a true Guardian, representing "Fun."
Before Jack became immortal and before his current attire, he had brown hair, brown eyes, and fair skin. His clothing consisted of a white v-neck undershirt with a brown vest and brown trousers. He also wore a brown poncho to covered himself from the cold. He was seen with ice skates but was never seen wearing them.
Jack now currently has white hair, striking blue eyes, and pale skin. He has a tall stature, albeit slim. His clothing is a blue hooded sweater, frost collecting around the ring of the collar, and wore the same trousers bound with lighter material starting from the knee down to the rather tattered and frayed bottom, and is barefoot throughout the movie. He carries around a magical staff with a G-shaped arch, resembling a shepherd's crook. It is Jack's gateway to help him unleash his powers of conjuring snow, ice, and frost. Jack is currently over 300 years old though with an appearance of a teenager.
Jack Frost is a mischievous teenage hellion who has no interest in being bound by rules or obligations, and rather instead favors spreading his winter magic for the sake of the personal amusement of himself and children. Despite these traits, Jack is also gentle and generous. The source of Jack's anti-social behavior towards the Guardians and refusal to adhere to rules was mostly because of his frustration with the Man in the Moon never answering his questions about who he was or why he was created, and also because no human, child or adult, was able to see him for centuries for no one had believed in him.
As Jack spends time in the Guardians' company, however, each individual would have an effect on him that would change him from a mischief-making winter spirit to a full-fledged Guardian in his own right, as well a hero. It was his refusal to give up in the face of overwhelming odds that enabled him to help one child, Jamie Bennett, who keeps his beliefs in all of the Guardians as well as finally being able to see and believe in Jack Frost. Jack's desire to protect Jamie, as he once did his sister, helped him realize his center; Fun. Jack proudly accepted the duties and responsibilities as the Guardian of Fun. His purpose, is to spread the feelings of fun, joy, and happiness to bolster the faith that children around the world had in the Guardians.
Even before he officially became a Guardian, Jack displayed some pride in what he does, particularly the Snow Days he makes for children to have fun. Jack was shown to have a somewhat low self-confidence at times, particularly in his status as a Guardian. His failure to save Sandy bothered him greatly before North told him Sandy would be proud of him for what he did and that no matter who Jack was in his previous life, he was a Guardian in this one. Jack worried about his human past, asking "how can I know who I am, until I found out who I was?" When Pitch was taunting him with his fears, he said that Jack was worried about his acceptance among the Guardians and didn't think they'd ever accept him, showing that he cared about their opinions of him. This was confirmed when the Guardians turned their backs on him and Jack was left heartbroken by it.
Even so, upon learning of his sacrifice to save his sister as a human, Jack's self-confidence was restored and he fully accepted his role as a Guardian, realizing he'd been one all along. Despite his deep desire to be seen, Jack is unwilling to stoop to the levels Pitch is willing to go in order to make kids see him. When Pitch offers to work with him to make kids see both of them, with being seen as Jack's greatest desire, Jack refuses when he realizes Pitch's way will make kids fear them and states that's not what he wants. This shows that despite however bitter Jack may have grown about his inability to be seen or heard, he doesn't want to be feared even if it would lead to belief. Rather, he prefers the kids loving him. This shows that he deeply cares for children even though they may never see or hear him and highlights why he is a Guardian. Due to his years of isolation, Jack seems to be taken off-guard by shows of affection. An example of this was when Jamie hugged him. Jack was so caught off-guard that he didn't even respond for a moment but then warmly returned Jamie's hug. He was also surprised by Tooth hugging of him after he officially became a Guardian but didn't seem to mind it.
Before Jack Frost became an immortal being who possessed the power over ice and snow, Jack was once a teenage human boy who had a family of his own 300 years before the current timeline. Like his current form, Jack was mischievous, liked to have fun and play tricks on his friends and his younger sister.When Jack and his sister got themselves in trouble while they were ice skating on thin ice, Jack made up a game of Hopscotch, and using his staff, Jack saved his sister from the cracking ice, at the cost of his own life.
The Man in the Moon, seeing Jack's selfless act of heroism and sacrifice, shines his light and transforms Jack into a Winter Spirit, of which Jack rises up from the frozen pond and he is reborn as Jack Frost. When Jack Frost was reborn he lost all memory of his previous life and immediately began his adventures of fun and mischief, discovering his powers. The Man in the Moon only ever told him his name, and he quickly discovers no one can see him when he enters a village and is walked through for the first time.
The story continues with Jack causing mischief in St. Petersburg, Russia. Noticing it was a fun day, he calls the wind to take him back home, to Burgess. As he arrives at Burgess, he decides to give it a snow day. While Jack is having fun, he accidentally knocks a book out of the hands of a child named Jamie with his wind. Jack finds the book interesting and asks Jamie about it, but Jack knows that he can't be seen or heard by Jamie. Just then Jamie's friends, Caleb and Claude, rushed to Jamie and tells him about them having a snow day and Jamie asked them if they were going egg hunting on Sunday. Jack followed Jamie to his house listening to their conversation. When the boys bring the Easter Bunny in to the conversation Jack joined, saying that Bunnymund is real annoying and full of himself. When Jamie's mom comes out of the house to give Jamie his winter hat; she brings "Jack Frost" to the conversation by saying: "Careful! You don't want Jack Frost nipping at your nose!"
"Who's Jack Frost?" Jamie asked his mother.
Jamie's mom smiled. "No one, honey. It's just an expression".
Jack takes that offense and decides to have a little fun with Jamie, so Jack throws a magic snowball that hits Jamie in the back of his head causing a snowball fight between him and his friends. When Pippa accidentally hits Cupcake, and everyone gets afraid. Jack, wanting to continue with the fun, hits her with a snowball, changing her attitude from mad to happy in which starts a game of chasing. The ground was slippery causing Jamie to fall in his sled and skate to the street, so Jack makes an ice path around the street and helps Jamie return to the park where Jamie flies so high that he goes over the statue of Thaddeus Burgess and gets hit by a sofa. Jamie, excited, reveals that he lost a tooth causing the conversation to change to the Tooth Fairy. Jack tried to remind them about the fun they just had, but his beckoning turns to sadness when Jamie walks through him.
Jack is later spying on Jamie that night when he tells his family about the fun adventure he had and the new drawing he made. He also tells them about the tooth and planning on seeing the Tooth Fairy. Jack then leaves and asks the Man in the Moon what can he do to be seen by someone as he has tried everything. Just then the Sandman's Dreamsand arrive.
Jack intercepts the Dreamsand causing it to change to the shape of a dolphin. Just then a shadow passes him. Jack, curious, follows it to an alley revealing to be Bunnymund. Bunnymund mentions they haven't seen each other since the Easter Sunday of 1968 (which Jack made a snowstorm occur). Jack asked Bunny if he was still mad about it, but just then by two Yetis grab him, shove him into a sack, and throw him through a magic portal transporting him to the North Pole.
At the North Pole, Jack meets up with the Guardians and they reveal that Jack was chosen by the Man in the Moon to become the next Guardian and that Pitch has returned. Jack turns down the offer as he doesn't want to be someone who's stuck somewhere, finding ways to bribe kids. Tooth tries to explain what they do and the joy they bring to kids, but Bunnymund thinks Jack doesn't know anything about bringing joy to children causing a fuss between him and Jack.
North takes Jack away and explains to him about The Man in The Moon must have known that Jack has something special in him and North reveals his center, which is Wonder, through the use of a nesting doll of him. Jack, still confused, doesn't know what his center could be. Just then Bunnymund reveals there's trouble in Tooth's Palace and they have to make their way to help Tooth.
On their way there, it's revealed that Pitch has sent his Nightmares to catch all the fairies and collect the teeth of the children of the world. Jack saves Baby Tooth from one of the Nightmares before they arrive inside of the Palace to find a panicking Tooth. Pitch then confronted the Guardians and after a battle between then he escapes.
Jack, curious, asks why Pitch took the teeth and Tooth reveals that the teeth hold the greatest childhood memories, the reason why she collects the teeth. She also reveals that the Guardians were all somebody before they were chosen by the Man in the Moon, even Jack. Jack, surprised, asks her about his past life and about his family to which Tooth asks if he really doesn't remember anything and that she can't help him since Pitch has his tooth box.
North plans to collect the teeth to keep the children believing in Tooth. North asked Jack to help them collect the teeth and in return they would help him get his memories back and Jack agrees to help them. The Guardians go around the world collecting teeth and making a competition of it. When Tooth tells them they were as fast at collecting teeth and leaving gift as her fairies, the guys realize that they forgot to leave a gift and have to travel back around the world to leave the gifts.
The Guardians all gather in Jamie's room but caused an uproar that caused Jamie and his dog, Abby, to wake up and see them (except Jack). Abby starts growling at Bunnymund and Jamie tries to stop her. Jack wanting to have fun with Bunnymund, makes the alarm go off, causing Abby to attack Bunnymund and make him jump around the room. Sandy, trying to put Abby to sleep with his Dreamsand, ends up hitting everyone except Jack, Jamie and himself. Jamie flies out of bed when North lands on it and Sandy catches him. Sandman puts Jamie to sleep and then goes to fight Pitch's Nightmares that have appeared with the help of Jack.
Jack is confronted by Pitch until Sandman joined him and slammed Pitch against a few building, with Jack commenting on not getting on the Sandman's bad side. Pitch pretends to be afraid of the two until he reveals his Nightmares. The other Guardians soon join in, but they are still suffering the effects of the Sandman's Dreamsand and are half asleep. Soon Jack and Sandy are in the sky battling the Nightmares, but the Sandman is surrounded and soon Pitch attacks him, turning him into more nightmare sand. Jack, seeing what happened rushed towards Pitch, who attacks him with a wave of nightmare sand. Jack used a powerful wave of ice which destroys the nightmares, but he started to fall from the sky until he was rescued by Tooth.
Back at the North Pole, the Guardians make a memorial for the Sandman. The Guardians decide to work hard for Easter so they could keep the children's belief in the Guardians. When Bunnymund transport them back to his Warren they find Jamie's sister, Sophie, has used one of North's snow globes to be transported to the Warren. Jack used his special skills to make Bunnymund more relax and to open up to fun, so he could play with Sophie. After the eggs were ready, Sophie fell asleep and Jack decides to bring her home. After Jack was able to put her on her bed, Jack heard a voice calling him. The voice led him to Pitch's lair where he found the kidnapped fairies and was confronted by the Nightmare King himself.
Pitch tempted Jack with his memories and taunted him with his fears of not being believed in, keeping Jack distracted long enough for his Nightmares to destroy Easter. Once this was complete, Pitch finally gave Jack his Tooth Box before disappearing. Jack then suddenly remembered that he forgot Baby Tooth, as well as finding himself standing in one of Bunny's tunnels, seeing before him that all the eggs they had worked on had been destroyed.
Jack saw the children stop believing in Bunnymund and found the Guardians disappointed. They told him that the Nightmares attack the Warren and the eggs didn't survive the confrontation. When Tooth asked about Baby Tooth and where he get the Tooth Box, Jack couldn't answer and ended up losing the Guardians' trust in him.
Jack made his way to Antarctica so he couldn't mess up again, but was confronted by Pitch, who wanted to recruit him. When Jack refused, Pitch revealed he had Baby Tooth and told him he will give her back if he gave him his staff. Jack agreed, but Pitch tricked him. Baby Tooth pecked Pitch's thumb, making him threw her away while he broke Jack's staff afterward. Pitch attacked Jack with nightmare sand which slammed him against an iceberg making him fall into a crevice. Jack found Baby Tooth and felt sad that he kept making mistakes. Soon after Jack's memories called him again, making him remember that he still has his Tooth Box. Baby Tooth taught Jack how to use the Tooth Box, which revealed Jack's human past. The flashbacks showed Jack some of the fun memories he did have with his sister and also showed him the moment when he saved her from the ice. These memories made Jack realize that he always has been a Guardian and gave him the courage to fix his mistake and save the Guardians and the children of Earth from Pitch. Jack was able to fix his staff and made his way back to Pitch's lair to rescue the fairies, but found out that they couldn't fly since there were only a few lights left. Jack noticed that the last light was Jamie and he made his way back to Burgess to recruit Jamie.
That night Jack rushed to Jamie's house to get him, since he's the last believer in the world, Jack finds him talking to his stuffed bunny asking him (Bunnymund) to give him a sign so he knows he's real. Jamie seems to start losing hope in the Guardians until Jack makes an egg with his ice powers in his window. Getting Jamie's attention, Jack makes a bunny and makes it come to life and jump around the room. Jamie gets excited and starts jumping in his bed until the bunny turns into snow, resulting in a snowflake to nip at his nose and for him to believe in Jack Frost. Jamie asked "Jack Frost?" which caused Jack to look at Jamie and wonder if Jamie believed it him.
When Jamie revealed he can see and hear him, Jack gets excited about having his first believer. When they hear North's sleigh, both of them rush outside. Jamie reveals that he can see Jack and the other Guardians. Bunnymund thanks Jack for making Jamie keep his belief in him.
When Pitch appears, Jack goes to fight him, causing the other Guardians to lead Jamie away. Pitch being more powerful than before beats Jack and makes him fall to the alley where the others were. Pitch traps the Guardians and Jamie, Jamie tells Jack that he's scared. Hearing that, Jack gets a memory of the same thing his sister once said causing Jack to realize what his center is: Fun. Pitch approaches them but was hit by a snowball by Jack. Distracted, they escaped and went to gather up Jamie's friends.
With the help from the other Guardians, Jamie's friends start to believe again. Pitch asks them who was going to protect the Guardians if the Guardians were protecting them. Jack reassured Jamie to not be scared since the Nightmares are just bad dreams and Jamie volunteered to protect the Guardians causing his friends to join him. Pitch then sends a wave of nightmare sand their way but once Jamie says, "I do believe in you. I'm just not afraid of you!" Jamie was able to turn the nightmare sand back into Dreamsand. Which helps the Guardians get their full energy back and battle Pitch. North used his snow globes to bring his Yetis to help out while Bunnymund opened tunnels to get his Warrior Eggs to also help in the battle against the Nightmares while the Guardians confronted Pitch. Jamie gets an idea on how to revive the Sandman and told his friends about it. As the battle with Pitch continued, the Nightmare King was cornered by the Guardians, but hid in the shadows and appeared behind a distracted Jack with scythe created out of nightmare sand, but before he could hurt him, the Sandman returns at the last second saving Jack from Pitch and uses his sand to give everyone good dreams and make more believers.
The Guardians and the children started celebrating and Jack hits Jamie with a snowball, which caused a friendly snowball fight. When Pitch woke up, he tried to make Jamie fear him again but found that Jamie was not scared of him anymore because he was able to pass through him.
Pitch, afraid, retreats to his lair which caused the Guardians to follow and confront him one last time. After Pitch was taken away by his own Nightmare creatures, the Guardian ceremony was performed again. Jack looked at Jamie which caused him to nod. Proud of himself and of Jamie, Jack says, "I will," making him an official Guardian. "Then congratulations, Jack Frost, for you are forevermore...a Guardian." North closed the book. The kids cheered wildly. The yetis and the eggs celebrated.
Amid all the celebrating, Jack noticed the Mini Fairies flitting about, swooning and fainting with joy. Caleb pointed to something huge in the sky and Monty identified it as Santa's sleigh. After everything they'd seen, the kids still couldn't believe their eyes at the sight of the sleigh.
"Everyone loves the sleigh," said Bunnymund, with North chuckling. Then North saw the sun rising higher in the sky. "Time to go," he told the Guardians.
Sandy threw Dreamsand up into the air. It floated down softly and landed on Jamie and his friends, who began to yawn and stretch.
"You're leaving?" Jamie asked drowsily. "But what if Pitch comes back? What if we stop believing again? If I can't see you..."
Jack knelt down to look Jamie in the eye. "Hey, slow down, slow down! Are you telling me that you stop believing in the moon when the sun comes out?"
"No," Jamie replied.
"Okay, well, do you stop believing in the sun when clouds block it out?"
"No," Jamie repeated.
"We'll always be there, Jamie. And now" - he pointed at Jamie's heart - "we'll always be here." Jack smiled. "Which kinda makes you a Guardian too."
Jamie was proud. Jack makes his way toward North's sleigh but he is stopped by Jamie calling his name. Jack turned around and is surprised by Jamie who gave him a hug, which shocks Jack, but he eventually returns the hug.
Jack smiled as he stepped into the sleigh with the other Guardians. Jamie waved good bye as the sleigh began to speed along the ground. He ran behind the sleigh until it lifted into the air, heading to the North Pole.
Jack was happy. Happy to have helped defeat Pitch and to finally know who he really was: a Guardian. He turned back to watch Jamie as the sleigh careened into the morning sky.
"My name is Jack Frost, and I'm a Guardian. How do I know that? Because the moon told me so. So If the moon tells you something... Believe it." He formed a snowflake in his hand and let it go.
During the Epilogue written by Louie Del Carmen, a curious Jamie woke up, wondering if any of the events of the night before really happened. To reassure Jamie that the Guardians will always be there, the Guardians left Jamie some gift in his bed except for Jack whose gift was a snowflake waiting for Jamie at the window. 
- Main article: Nightlight
Before Jack Frost was Jack Frost, he was Nightlight, the most trusted and valiant companion of Mim, the Man in the Moon.  As Nightlight, he has appeared in every novel of the Guardians of Childhood series, but as Jack Frost, he has yet to make his first official appearance.
Powers and Abilities
Jack is both the Guardian of Fun and the Spirit of Winter, surprisingly powerful and a cunning trickster. It's his job to make children have fun, while bringing joy and fun times with Winter and snow days, thereby making them happy and bolstering their faith in the Guardians.
As the Spirit of Winter, Jack can summon snow, ice, frost, and later learned he can unleash energy bolts of ice, and he can easily freeze things over/solid with a mere wave of his staff. Originally, Jack channeled his Winter Magic through his staff, mistaking it to be the source of his power, when really it was just a conduit to help keep his powers under control. Jack can conjure ice, snow, and frost from his mere presence, as well as freezing winds, snowballs, snowflakes, etc. Jack can even manifest images from frosted window panes, freeze water by walking on it, and conjure indoor snowfall, and of course, being the spirit of winter, he is not bothered by the cold.
Jack is able to fly by riding the wind. He flies by floating like a snowflake, and propels himself with wind to fly faster.
Magic of Fun
As the Guardian of Fun, Jack can bewitch others with feelings of fun, joy, and laughter with his snowballs or even his snowflakes. This was first seen when he hit Cupcake with a snowball, quelling her anger, and helping her have fun and become friends with Jamie and the other kids.
Jack is a very skilled free runner and can quickly move across rooftops or even weave through traffic with uncanny speed and agility, as he safely directed Jamie on an epic sled-ride.
- Main article: Twinetender
Jack has a magic staff with which he can control the elements of winter. Jack's staff name is Twinetender (Twiner for short) and came from an a willow that stood on the ancient burial grounds of Mohican Indians. The Mohicans called it Warriors Willow for from its branches came the strongest and most flexible bows, staffs and arrows that their warriors and hunters fashioned. The warrior dead of the tribe were buried among the willows roots and each limb was said to have the spirit of a warrior within its heartwood who could help the person that wielded it, but only if that being were brave and true of heart. Jack's staff was his friend, his comrade his protector. It would alert him to danger. It could focus Jack's power to speak to the wind and learn the language of leaves; which allows him to fill the sky with leaves and twist them about as he wills. The leaves can also act as a shield or blister down like charging cavalry. Originally, he thought this staff was the source of his power, when really it was just a conduit for him to channel the magic of winter that had really been inside of him, seen when he repaired it through sheer force of will after Pitch snapped it in half.
Another ability granted by his staff, it's the ability to evolve into a fierce and noble friend to Jack as a warrior and a confidante. 
Jack's battle style consists of Parkour and Kendo (means "way of the sword"). He combines free-running with Martial Arts to make a unique battle style.  With perfect timing and skills, Jack is able to dodge an enemy attack and instantly response by calculating his body and staff movements to be able deliver his own attack. He also pays close attention to an enemy movements since a response that is too slow or fast may not be effective.
Physical Age Manipulation
After Jack had been victorious in his penultimate battle with Pitch, he went through many extraordinary changes. He was able to physically age himself (up to a point) or become younger at will.
Jack Frost has a special kinship among the world of leaves. He can command the leaves of any tree or plant (other than Mandrake) and use them as spies to keep watch for Pitch. They can change color, fly and even return to their tree if he tells them. They speak to Jack as though he were one of them and revere the magic lad as a king. His strength and power derive much from the realm of nature and his mysterious friendship with the being known as Mother Nature.
The Guardians of Childhood
- As Nightlight
Rise of the Guardians
Creation and Conception
One of the first characters for which Hordos and Wanneroy developed a performance was Jack Frost. “We had to decide whether Jack Frost could fly, and if so, how,” Hordos says. “And then, we needed to know how he walked.” Rather than turning the mischievous character into Superman, they decided to have him fly in the wind with the abandon of an expert skateboarder slaloming downhill. “He’s had 300 years to learn how to do this stuff,” Hordos says. “So, we had him relaxed and super cool, flying with his hands in his pockets, doing flips. Then, Dave Pate, the supervising animator, took him to another level, of a soul caught in this realm. Everyone believes in the Guardians, but no one totally believes in Jack Frost. So, he’s completely isolated, and he’s a troublemaker. He brings signs of winter and causes chaos. Pipes freeze. There are winter mishaps and inconveniences. But winter also brings snowball fights and things kids love.” The effects artists gave Jack his frost, a visible display of his emotions that could also serve as a weapon. “He can grow beautiful floral patterns calmly and slowly, or, when he’s fighting Pitch, shoot bolts of frost,” Prescott says. “The system we developed was really controllable. We could grow frost in a room over a table, over a couch, and down the other side. It looked organic.” The system developed by effects lead David Lipton, who joined DreamWorks Animation after working at ESC on the Matrix sequels, uses cellular automata to grow the frost. “We looked at L-systems, but we needed to have the frost grow, turn left, turn right,” Prescott says. “L-systems would have fallen apart. With cellular automata, we can set a seed and draw a line for where we want the growth. And, as with a fluid simulation, we can put things in the way.”

- Interesting to note that Jack Frost has special connection with Jamie Bennett and that Jamie resembles somewhat Jack Frost's sister. It is possible that Jamie is a descendant of his sister which might be the reason Jack felt drawn to Jamie. When Peter Ramsey, the director of ROTG, was asked about this, he answered: "Who knows…! It could be possible… One of my regrets is that we didn’t have more screen time in the movie to flesh things out a bit more. Is there a bigger connection between Jamie and Jack? Yeah, that could be a definite possibility, that there’s some kind of lineage connection like that. It’s one of those movie mysteries."
- According to The Guide to the Guardians:
- Favorite Activities: Snowball fights, sledding, trying to sneak in to the North Pole.
- Preferred Mode of Travel: Rides on gusts of wind like an Olympic snowboarder.
- Favorite Thing: The Perfect Prank.
- Takes great care of his sparkling snow-white teeth.
- According to William Joyce, mice and fairies make his clothes and sometimes urban outfitters.
- He also revealed that Jack's hoodie is actually from Ye Oldie Outfitters of Urban Yore.
- Generally Jack only makes the noses of people he thinks are mean to kids feel cold. Bullies. Mean teachers. Orthodontists.
- William Joyce has stated that he thought a great deal about Errol Flynn’s Robin Hood when creating Jack, and that Jack is equal parts Peter Pan and Robin Hood, pointing out many similarities between them.
- Both seemed invincible.
- Both seemed to be having the best time being the hero.
- Robin and Peter are both clad in green tights and live in the forest with a bunch of rowdy fellas swashbuckling against tyrannical adults. Robin’s men of Sherwood are tall versions of the Pan’s lost boys. They commit cheerful anarchy against the venial royals of Nottingham with the same insolent joy as the lost boys made mischief with Captain Hook. And for both stories it took a girl to bring calm and an almost adult element to the heroic hijinks. Wendy in Neverland. Maid Marian in Sherwood. But both stories hide their depth and poignancy behind a screen of swordplay and adventuring. And in both stories it is the girl who guides us to the tragic undercurrents of the hero’s life and journey. For Jack Frost he found himself pulled in a similar direction. For all his strutting and smiles he is a lost boy desperate to find out it if he can love and be loved. His only vulnerability is his care. His deep, unwavering love is his salvation but also the source of all of his danger, worry and pain. And like Robin Hood he will face any hardship to protect his hearts desire. Love makes us all grow up. The great tragedy of Peter was he would not, could not love Wendy. Or anybody. He could never leave Neverland. Robin Hood saved the king and England but only with Marion’s help and love. It’s poignant when he and Marion wave goodbye to Sherwood but for them it’s time to move on. And so jack comes to a similar juncture. He wants so desperately to move on. To feel. Love makes heroes of the lost and lonely. 
- He was at first inspired by Peter Pan the boy who could never grow up. As Jack began to evolve in his mind he thought a great deal of James Dean the movie star who never really grew up. He rocketed to stardom playing a teenager and was dead before he’d finished his third film. He is forever frozen in his celluloid perfection of rebellious youth. Then the very young Leonardo DiCaprio. In “This Boys Life” and “The Quick and the Dead” DiCaprio had a Huck Finn quality that was full of canny mischief and danger. And he was for a brief time cast to do the voice of Jack. But as time passed Jack’s qualities became the dominion of Joyce's two children. Particularly the kindness and courage they displayed as tragedy cut short their childhoods. They became the children who had to grow up and face the worst that fate could conjure. But they held tight to their memories. And that became Jack’s defining quality. Unlike Pan, Jack Frost knows there is an end to childhood, he knows that heartbreak and hurt are coming. But he will use memory as a weapon to keep the darkness at bay. As Joyce drew this image he thought of all these things. And of NC Wyeth and his great romantic flowing cloaks. He listened to Debussy and George Auric and New Order. Art and writing can seem like lonely endeavors. But remembering the inspirations can make the task feel like a warm gathering of treasured colleagues. 
- Additionally, Jack's death was the result of him drowning in a lake covered by thin ice to save his younger sibling from doing the same. The exact same occurred to Peter Pan author J.M Barrie when he was a young boy, when his older brother saved him from drowning in a lake covered in thin ice. This was his inspiration for the title character who, like Jack, is also someone who can fly, has a fairy companion, and will forever remain a boy.
- According to William Joyce, there are several partners that Jack is drawn to. He does not realize it, but he is deeply lonely and he doesn't want to stay alone.
- William also revealed that Jack is naive. And innocent. He doesn't understand romantic love. But he's starting to have feelings that confuse and confound him.
- Jack is highly regarded by the Fairy Folk, and they often aide him in battle or defend children and other noble creatures. William Joyce has stated he's sure they live in Jack's Tree of Sorrow. He even carries a small troupe of them with him from time to time, in a small pouch that hangs from his waist.
- Jack makes an appearance in the mobile game: ‘’’Dreamworks Universe of Legends’’’.
- According to the app, Jack Frost is a supernatural being much like the Guardians. But unlike the others, he is a loner, the classic rebel without a cause. He too is immortal, eternally young charismatic, and smart. He has incredible weather powers that he controls with the help of his magical staff; he can call the wind, storms, cold and snow. He rides the wind like an Olympic snowboarder. He is the spirit of mischief and chaos personified and has yet to harness his full potential.
