Perhaps I mentioned this before, but my personal favorite JLA chairperson was the Gerry Conway pet character, Zatanna. She bossed around valuable characters, showing a suprising degree of battle ability and grit. She bossed Superman around on several occasions.
I forgot about Zatanna --maybe because I hated that costume.
Chairperson in JLA. Chair in Avengers too, no? Or is it a generic "team leader"?
Avengers leaders are called "team leaders." The term "chairperson" is also used, but inconsistently. Like the Legion of Super-Heroes, the Avengers vote for their leaders.
The position is given a higher degree of elevation in that team because, as a result of the more volatile personalities in that group, there is some jockeying for leadership position. The most famous of this was Hawkeye, who wanted Captain America's job during the early days of Stan Lee's run, until the two of them reached a mutual understanding.
"She looks at that over-aged square like he's the only joe in the room. Chicks only go after the guy that's top dog - just my luck it hadda be HIM!"
Other great Avengers leaders besides the famous Captain America include the Wasp (who was surprisingly competent despite a ditzy reputation - perhaps inspired by Zatanna's assumption of leadership position?), Hawkeye (whose acquisition of dignity and mellowing out is one of the great gradual alterations to characters in comics). Iron Man was chairperson on several occasions, as was Thor.
Is that when she was wearing that silly white costume? 'Cause I loved the fishnets and hotpants.
That's the white costume she wore in her Gerry Conway years, the white one. It was a good costume, but perhaps not "Zatanna."
Though the giant earrings with the "Zs" in them were pretty neat.
