X-Men team up with Amazing Spider-Man in post credits scene (X-Men Days of Future Past - Jaa Smith-Johnson)

Marvel movies typically end with a tie-in for a sequel but The Amazing Spider-Man 2 cut the post credits scene, which reportedly featured the frozen head of Norman Osborn. In its place is a clip from X-Men: Days of Future Past.

The shapeshifting mutant Mystique (Jennifer Lawrence) impersonates a soldier to rescue a group of mutant soldiers from being held against their will at the end of the Vietnam War.

Alex Summers AKA Havoc (Lucas Till) is originally the brother of Scott Summers AKA Cyclops but will have a different connection in the film. He can fire energy blasts of cosmic energy that are cancelled out by Cyclops and vice versa.

Toad (Evan Jonigkeit) is an original member of the Brotherhood of Evil Mutants. He has a prehensile tongue with and paralyzing mucus.

Ink (Gregg Lowe) is a regular human who receives powers from a mutant tattoo artist. His tattoos includes the Phoenix Force symbol on his eye that gives him telepathic powers similar to Jean Grey as well as a bio-hazard symbol on his hand that he uses to make the soldiers physically sick.

Jaa Smith-Johnson portrays an unidentified mutant soldier with porcupine quills as well as cloudy eyes that seem to make the human soldiers dizzy; however, it may be from Ink’s power. He appears similar to Kid Omega from X-Men: Last Stand, who was based on Quill or Spike.

Mystique reveals that she is operating independently of Erik Lehnsherr AKA Magneto (Michael Fassbender), who is being held prisoner by the government. It’s possible she forms a new Brotherhood of Evil Mutants that results in the creation of the mutant hunting Sentinels that wreak havoc in the future, which Wolverine travel back in time to prevent.

X-Men: Days of Future Past release date: May 23.
