WATCH: Wolverine Drops by in Final Trailer for ‘X-Men: Apocalypse’ 

The superhero squad is getting some help from an O.G. mutant in the summer blockbuster’s latest trailer.

It appears Mystique (Jennifer Lawrence) is forced to become a mentor to the next class of X-Men, including Jean Grey (Sophie Turner), Cyclops (Tye Sheridan) and Nightcrawler (Kodi Smit-McPhee), in the franchise’s new film, teaching them how to fight and survive as outsiders.

This time out they must face an ancient creature known as Apocalypse (played by Oscar Isaac, although he is entirely unrecognizable), a formidable enemy and perhaps the first mutant. Apocalypse appears to have no trouble squaring off against Professor Xavier (James McAvoy), growing ten times larger in mere seconds and throwing the revered leader around with ease.

But the real gem of this trailer is when an old fan favorite lends a hand, err claw, to help the newbies when they land themselves in trouble. Check it out above!

X-Men Apocalypse soars into theaters on May 27, 2016.
