The name's Jack Frost. Nice to meet ya. I'm a Winter Spirit and the newest addition to the Guardians; the Guardian of Fun. (Definitely an improvement there, I'd say. They could certainly use someone like me around.)
For three hundred years I went unseen, but that's another thing that has changed for the better. I'm no longer invisible, now I'm believed in.
I'm here for all of you and forever willing to brighten your days!
