If you've seen the X-Men trailer for Avengers Doomsday, you might have noticed the familiar location of Xavier's School for Gifted Youngsters, now in disrepair. Professor X and Magneto appear as comrades facing a new threat, symbolizing a final stand for the X-Men.
Possible storylines teased in the trailer include the '2015 Secret Wars' event, suggesting a collision of universes, and a nod to the tragedy of Genosha from the comics, where Sentinels raze mutant habitats.
Another interesting detail is the potential involvement of new generations, such as Thor's daughter and young Avengers, hinting at future developments and battles against looming threats.
