Yellowjacket 2 wasn't black, possible latina, her name was Rita DeMara. I don't know if she ever headed the team... unless everyone was in a coma or something. But you never know. I remember she joined the Guardians Of The Galaxy in the 31st century. But when she came back, Iron Man killed her.
I mean c-mon a big super strong black dude with steel hard skin and an attitude , plus a martial arts master who can transform his fist unto a thing like iron ?!?! plus he's (iron fist) rich. How can you not like 'em , like the superhero version of Lethal Weapon.
My favorite team is the DOOM PATROL. The reason is because it had an innovative idea at that time, that is, the idea of superpowers making somebody into Not a hero but rather a FREAK. For example, Negative Man's radio-active body made him dangerous to everybody else, so he was SHUNNED by normal people.
The DOOM PATROL'S idea of a superpowered person getting shunned and persecuted actually PRE-dates before the debut of the X-MEN, so the X-MEN are NOT the first to use that idea.
But I also love the X-MEN for the same reason, and consider the first Patrick Stewart movie as the best of the superhero books adapted for the cinema.
My admiration for the X-MEN film has brought me back to the X-MEN books again. So I guess it's a toss-up between X-MEN and the DOOM PATROL. But I have to say that the reason why I like the X-MEN is BECAUSE of my love for the DOOM PATROL.
