While many known character could be appearing in Apocalypse on the different side than they started, this could be the case for Nicholas Hoult's Beast who could always go with the Dark Beast storyline from the comics.

Channing Tatum Could Start As An Agent Of Apocalypse In Next X-Men Movie

In the comics, in the alternate dimension he came from, Hank McCoy was a mad scientist working for Mister Sinister in his breeding pens, intent on breeding more powerful mutants according to Apocalypse's "survival of the fittest" ideology.

However, while Sinister was methodical and rational in his experiments, McCoy (as ruthless as his mentor) sadistically delighted in causing pain to his lab subjects and in the cruelty of his experiments, which is why he was nicknamed the Beast both by prisoners and Sinister's Elite Mutant Force.

McCoy also experimented on himself in order to further his mutation, and gained his ape-like bestial appearance. Any mutant that he deemed unworthy was turned into a component of a genetic stew that was used to create Apocalypse's army of Infinites.

He also experimented on Blink and created another version of Wolverine. This is a possibility as Blink has already been confirmed to return for the next movie and Wolverine has the possibility of being Weapon X during this movie.

This plot would be a different one for Hoult, whose character has been close to McAvoy's Professor X in both movies so far, but could take shape if the reality that Professor X dies happens during the movie.

X-Men: Apocalypse is set to open in theaters on May 27, 2016.
