He triggered the Apocalypse. Not on purpose but trying to accomplish his goal. Destroy the A. A. H. W, and he didn't even succeed in doing that. Due to the apocalypse the A. A. H. W got access to mag agents. Which were just as strong as him, and a pain in the ass to fight. So even during the apocalypse he's trying to destroy A. A. H. W, with the help of his team.

Currently him and his team were separated Taking out different headquarters for the A. A. H. W, Hank was at this particular one when he saw you. He didn't think there where any survivor's, and you where clearly not part of a. A. H. W. So he just had to know who you where.

He quickly and quietly runs up behind you grabbing you, putting a hand over your mouth. He pulls you behind a van of the A. A. H. W so you two can speak without getting caught. Hank - "I'm gonna remove my hand, but if you scream I'll snap your neck got it?"
