Doctor McXapp

Doctor Alastair McXappingham is Mayor McFlapp's X-Antibody. He hates his genetic brother and wants the position of Narrator all to himself. McXapp is quite smart and devises mastermind plans to snatch Mayor McFlapp's position, but the Mayor has the advantage of the Fourth Wall and almost always foils McXapp's schemes.

Background
Mayor McFlapp, like most Antarctic creatures, had the X-Virus. However, he was aware of it, and thus set the Lithium Improbability Drive to prevent the Virus activating, releasing it only at a very awkward and improbable time.

The Drive kept the Virus at bay for months, until the day the Mayor was scheduled to meet with the government officials of New North Etana...

Inside his private jet, where he would be flying all the way down to the island nation, the Mayor was typing on his Narrator's PDA, narrating a small anecdote involving some Khanz Penguin who was destined to take the throne of Pengolia, when the PDA suddenly ran out of batteries.

"Oh, whackaday!" muttered the Mayor. "Just when I was in my element, wot!"

Suddenly, the Mayor began coughing severely. As he reached for his cough drops, he noticed his reflection in the PDA's screen.

"GAH! *cough* WHAT IS *cough* THAT?! *cough cough*"

A large, red "X" was imprinted on his top hat, and his eyes were red. The Mayor screamed, letting loose a large glob of black fluid, which rebounded off the wall and landed on the seat next to him, transforming into a black tern with white wingtip feathers and a weird nurse's hat with a red "X" imprinted on it. The tern's eyes were red.

"" said the evil-looking tern. ""

The Mayor, who was not about to let a creepy-looking tern X-Antibody with a weird hat take over his role as Narrator, just pressed a button on his PDA. The X-Antibody was teleported away, but not before saying this: ""

Involvement
Doctor McXapp constantly plans the downfall of his genetic brother in his secret hideout somewhere in Ternville. He likes devising complicated deathtrap schemes for the Mayor to get out of, only to have his plans foiled by the Mayor and friends.

Ironically McXapp was captured by Xplorer and controlled by Nightmare.
