The Guardians' Oath is an oath taken by the Guardians as a promise to protect and keep belief in the children of Earth.

The Oath

Will you, (name), vow to watch over the children of the world?
To guard them with your life, their hopes, their wishes, and their dreams.
For they are that we have, all that we are, and all that we will ever be.


The Man in the Moon invented the Guardian Oath many years ago when the first Guardians were brought together. The Oath was originally inspired by the last memory he had of his parents. They ordered to his protector, Nightlight, to kneel and take the oath:

Watch over our child. Guide him safely from the ways of harm.

Keep happy his heart, brave his soul, and rosy his cheeks.

Guard with your life his hopes and dreams,

For he is all that we have, all that we are,

All that we will ever be.

—MiM's Parents

MiM knew he too could be a guardian of the children of Earth, just like Nightlight was to him, and gathered his friends North, Katherine, Bunnymund, Toothiana and Sandy to the Moon, and like his parents before him, asked his friends to "Kneel and take this Oath."

The Guardians kneeling and taking the Oath

We will watch over the children of Earth,

Guide them safely from the ways of harm,

Keep happy their hearts, brave their souls, and rosy their cheeks.

We will guard with our lives their hopes and dreams,

For they are all that we have, all that we are,

And all that we will ever be.

—The Man in the Moon.


  • During Jack's ceremony, he looked at Jamie before he gave his answer to North, answering yes when Jamie gave him a nod of approval.
  • Jack's first ceremony was extravagant but his second was much more subdued though notably it was attended by a group of believers and not just the Guardians and their helpers with one of the believers being the first to ever believe in Jack.
