Santa Claus

In Sonic X #15, Sonic has a hard time believing that Santa is real. Sonic goes so far as to run to the North Pole and look for Santa's workshop. Later on, Dr. Eggman impersonates Santa, saying he will only deliver presents if the world delivers Sonic to him. Sonic is rescued by Chuck Thorndyke who claims to have the real Santa with him. Eggman is scared off by Santa, but it turns out it was actually Ella in a Santa suit. Now, Sonic and Christopher Thorndyke both doubt that Santa exists. On Christmas morning, Chris declares that Santa is real and Sonic (after getting a pair of Rings as a gift from Santa) agrees that it is good to believe in things.
