This rumble type amuses me again. So, in the ToP - flight was banned unless you had wings. So the Zenos come up with this.
No powers - everyone is set to an ability level based on a normal person of their species but allowed martial arts training - as long as it does not produce energy projection, time tricks, invisibility,etc. or anything outside of blows and kicks, grappling, chokes and the like. No one is invulnerable but being as tough as a normal member of your race is OK.
Here's my team. How do they do? Now Karate Kid is debatable beyond most but he's said not to have powers , just training. Now - are martial arts weapons allowed, I'm mixed on this but certainly no firearms, ray guns, bombs, grenades, etc. If you want batarangs, normal swords, ok.
