Return of the King
Superman: 65%. Superman is a much better fighter than people give him credit for, me included at one time. Aside from regular sparing with Diana and Batman and the rest of the League, Kal's style of reactionary fighting shows him adapting to whichever situation he's found in. His brief little scuffle in World of New Krypton against another Kryptonian shows that he's not some mindless brawler.
Orion: 95%. This should be a no brainer, honestly. Orion has been fighting for a long, long time.
Thor: 80%. Thor is pretty much one of the best brawlers in his weight class. The guy's sense of warfare and tactics have impressed Captain America before, not to mention Thor has defeated both the Asgardian and Olympian Gods of War (Tyr and Ares) like no one's business.
Flash (Wally): 30%. Wally's been around long enough to use his powers effectively as well as fight prolonged battles at very high speeds.
Captain Marvel (Billy): 45%. Thanks to his own experiences and the Wisdom of Solomon, Billy is able to hold his own against most foes.
Martian Manhunter: 40%. No explanation really needed, imo.
Black Adam: 55%. Adam is smart enough to go all out when he needs to and uses everything at his disposal to handle multiple heroes at once.
Silver Surfer: ?. To be honest, I haven't seen a whole lot of Surfer fights to make an informed judgement.
Supergirl: 25%. Her training with the Amazons as well as her cousin and Batman have paid off when she's been faced with powerful foes.
Power Girl: 50%. It's obvious from her recent fight with Diana, PG has some skill to her name. Regular training and sparring with the JSA - most noticeably Wildcat - keep her pretty sharp.
Sentry: 10%. Bob is basically like a super powered gun. Just point him in the right direction and pull the damn trigger.
Donna Troy: 80%. No explanation hopefully needed here.
Gladiator: 70%. It's obvious Glads is much more than a Superman-esque brick with a funky haircut. He has the skill to fight incredibly effectively.
