Yeah, this is fun.
Making up those established characters is a volatile thing, and tends to change according to the writers. I would do two version of each, one fast and rough-edge for use with a team, and the other one more min-maxed and detailed, for solo use.
I think you guys are giving too much points to some of these. Hawkman at 450? A little exessive IMO. Time to flex mine.
JLA
Superman; 700-900 pts, a STR of 90, SPD 6, dex 27, def 45.
Martian Manhunter; I don't know. He is a Superman with all powers. Regular martian stock, you know. 700-900 pts too.
Wonder Woman; 500-650 pts for the Greek but America-loving amazon.
Batman; 500-650 pts too, much in skills, gear and Find Weaknesses.
Aquaman; 450-600 pts.
Green Lantern; 450-600 pts, a huge variable pool with 0 END cost.
The Flash; 500-650 pts for the speedster to end all speedsters.
Avenger
Thor; 650-850 pts whitout Odinforce, STR 70, dex 18, a hammerfull of tricks.
Iron Man; 550-700 pts.
Cap America; 400-500 pts for the Icon, much of it in skills and CSLs.
The Wasp; 300-400 pts for this eternal underdog.
Scarlet Witch; 350-450 pts.
Hawkeye; No Avengers whitout this fave! 350-450 pts, a multipower.
Hank Pym, in whatever incarnation; 350-450 pts
X-Men
Prof Xavier; 350-450 pts
Marvel Girl (Jean Grey); 300-400 pts
Cyclops; 300-400 pts too
Iceman; 300-400 pts
Wolverine; 350-450 pts. I think this guy is overrated.
Rogue; My gawd. certainly 500-700 pts as designed. I don't like this concept.
Storm; 400-600 pts
Fantastic Four. I love this somewhat lackluster team.
Mr Fantastic; 450-600 pts, a great Variable pool, many Analyze skills.
The Thing; 450-600 pts typical brick
The Human Torch II; 450-600 pts too.
The Invisible Girl; Give this underated chick 450-600 pts too.
Now who wins?
JLA are the most powerful by far, their character ending up as the quintessence of their respective fields. However the Avengers are better-led and more polyvalent. The X-men are too, but does not seem enough disciplined to hold their own in this. The Avenger should win, with a little twist of plot. But if these teams were cut down to 4 members, they should all wield before the very synergic Fan-4. How can you lose with Reed Richards on your side?
