Assuming Batman is a 100:
Wonder Woman - 100, she is the god-created warrior.
Superman - 80, he would never quite but deep down he doesn't have the warrior/fighter mindset.
Wolverine - 105, given all the crap he has been through and keeps going.
Ben Grimm/The Thing - 105, as the Champion noted he will never give up.
Hulk - 110, due to rage and too stubborn.
Thor - 110, having every bone in his body broken, ground to paste, and staring down Ragnarok
Hercules - 95, tough but as some issues.
Marvel Ares - 90, he loves to fight but tends to run when things get tough.
Martian Manhunter - 85
Iron Man - 75
Spider-Man - 70
Starfire - 100
Orion of the New Gods - 115
Captain America - 100
Black Panther - 100
Doctor Doom - 100
Conan - 95
Red Sonja - 100
Kull - 90
Black Widow - 95
Is he not as heroic as any of the others?
