Jack & Jasper

Into The Alternate World.
After a fight with Pitch Black, Jack Frost ends up stuck at the bottom of a crevice with no powers and no way out. When he tries to fix his staff and restore his powers, he is somehow transported to an alternate universe. There he meets his "Opposite", Jasper Wintertide, a boy who looks almost exactly the same as him.

Personalities.
Jack Frost is very much like himself from the film. He's rebellious, mischievous and sarcastic but he also has a lonely side that can often be exploited by those wishing to use him and his powers for their own evil deeds. Despite these traits, Jack is also caring and gentle and deep down, he only wants to be believed in. His sarcastic nature means it can be difficult for him to make friends, but once he does, he is extremely loyal and protective.

Jasper Wintertide, however, is an arrogant, stubborn young man who only cares about himself. He fancies himself as a bit of a ladies man but isn't interested in holding down a real relationship. Although he is mischievous and rebellious like Jack, Jasper often takes things to far. Many of his jokes and pranks can be hurtful and cruel, and he is always getting into trouble. The physical differences between the two are Jasper's black eyes, but their personalities are what really set them apart.

Towards Each Other.
Jack is very cautious around Jasper and is almost afraid of him. When they first met, Jasper was really smug around Jack and acts like he knows a lot more than Jack.

Background.
Jack's background is the same as in the film up until the point when he has the fight with Pitch. This means he doesn't yet know about his past with his sister or that he is the Guardian of Fun.

Jasper's past is unclear, but as the story progresses, Jack will find out more about his mysterious look-alike.
