Death Metal ftw. I don't know anything about Alkhema, but DHII has tussled with Hulk before and actually fared ok...there was no clear winner, and Hulk would've won eventually on a neutral turf, but Minion was able to not die and eventually BFR'd Hulk out of a spaceship.
And Death Metal >>>> DHII. He also can't really die or be hurt by anything WWH can bring, and his mystically enhanced body would probably just cut Hulk's heart out or something.
...this is the Death Metal that owned the hell out of a full Alpha Flight roster (before they started jobbing to everyone), including a high-level metal manipulator (Madison Jeffries), and has healed in moments from nothing but a puddle of goo. Hulk's in trouble.
