Archie Sonic X Issue 15 is the fifteenth issue in the Sonic X comic series.
Christmas is just around the corner and Chris, Cream and the others are very excited about the upcoming holiday. That is, everyone but Sonic. Sonic has a hard time believing in Santa due to the fact that he can't understand how he gets around the world so fast. Sonic goes to the North Pole to find Santa and his workshop, but doesn't find anything there. He then goes back to the Thorndyke Mansion to tell everybody about what he just found. Just before Sonic is about to tell everyone, Chuck Thorndyke interrupts Sonic, takes him into a hallway and tells him that Santa only appears on December 25th. Sonic, still not believing Chuck, decides to drop the argument.
Soon after, at the annual tree lighting ceremony, Doctor Eggman intercepts the ceremony on a giant TV screen undercover as Santa and claims that he will only deliver Christmas gifts if the people of Station Square bring him Sonic the Hedgehog. As Sonic goes to Angel Island looking for protection, he soon realizes that if he is captured by "Santa", he could show everyone that he is really Eggman. Decoe and Bocoe arrive, hiding inside a Santa costume, in a sled to take Sonic to the North Pole. Sonic tries to rip the beard off, but it doesn't budge. He then sits tight and flies away in the sled. As the sled disappears on the horizon, a bolt falls from a robotic reindeer and is found by Chuck Thorndyke.
When Sonic gets to the North Pole, he is told to get inside a huge bag as he hears Eggman. He now knows this was a trap. Just as Sonic is about to be thrown into Eggman's North Pole base, Chuck Thorndyke and several others arrive in a helicopter. Chuck states that the real Santa is standing near the horizon. Tails then flies by, tossing Sonic a ring. Sonic spin dashes out of the bag and into "Santa", revealing that it is really Bocoe standing on Decoe's shoulders. Dr. Eggman escapes in his sled and Sonic decides to let him go until after the holidays. On Christmas morning, all of them receive presents from Santa.
