Is there any evidence that this character survived the explosion in X-Men: Apocalypse?

Question

In X-Men Apocalypse, is there any evidence that:

Havok/Alex Summers

survived the explosion of

the X-Mansion

?

Answer 1

He ded.

According to interviews Lucas Till (Alex Summers/Havok) did with CinemaBlend and EmpireOnline, he was explicitly told that his character had died in the explosion.

I thought it was really cool. I feel like people are always like 'Oh, it's X-Men. It's X-Men you can always come back.' But I was like 'No, I think it's cool that I died.' I think people were kind of nervous to tell me that I died but I thought it was really neat.

I figured it was just a matter of time. The producer and writers were kind of feeling me out with, “Are you okay with the fact that you die?” and I was, like, “Yes.” That’s something that people would talk about, so I thought it was cool that I died. Havok was in three movies and then I get to be remembered. It ended a chapter of my life and I get to start a new one with MacGyver.

That being said, he does recognise that his character could somehow return, if the writing requires it.

But also it is X-Men and you don't really see me die and if I can withstand cosmic energy coming from my chest I might be able to withstand some extreme levels of heat. Maybe that level fell just right so that maybe I survived, I don't know. I thought it was cool though.

Answer 2

As of right now, no. However, it should be noted that this is an X-Men storyline, and the characters have a bad habit, in both the comics and films, to not stay dead. Ray Park's character, Toad, even comments on this, after seeing Jean Grey surviving his earlier slime attack and Storm still being okay after being dropped down an elevator shaft in the first film.
