Hank has taken an unwanted vacation into the world of MHA, let's see what he can do away from all the madness... (On Ao3) cover by eggdue(me). Chapter 7 and onward is a reboot

The infamous trio has been thrown through reality into a strange new world. A world of heroes, villains, and everything in-between. A world that knows nothing of the horrors in Nevada. These horrors will soon follow them. There will be no kindness, nor mercy. Only Madness.

Awoken in a strange lab with no recollection of memory, identity or purpose. A rebel organization found him and gave the subject a purpose.
