ooooh ok. i thought mr blue was tony stark. mr fantastic would make sense and so wouldnt beast. but also high evolutionary, mr sinister too. but the hulk universe was wierd.

[SPOILER="mr blue spoiler"]
when the hulk blood dropped onto him and his head made a weird shape. i thought it might have been dr samson. but i dont read the hulk books ever, so i was wrong. then i was reading the hulk bio on wiki and saw the leader was an enemy i forgot about. the leader and abomination are his 2 biggest ones, and it clicked. stern is the leader! awesome.
