PL6? Alrighty, then.
What do you mean buy 'buy-offs?' I'm still very new to the system (as in I just made my first character [with much aid] over the weekend), so I may be a bit slower on the uptake.
My first thoughts on a character are for a super martial artist type, with a supernatural battle aura, a la Raoh's aura of giant angry fists that deck anyone who gets near him (Hokuto no Ken). The problem becomes, how should I go about representing that? I'd rather it be something passive or almost-passive, as well as directly destructive.
My first thoughts are some form of Strike. A Strike Aura? I'm not sure if that's legal, and the exact mechanics seem like they may be unreasonable. After all, if I punch someone, they'd be affected by the punch and the aura, for two attacks, and if they punch back, that's another attack, so that may take some finessing to make acceptable. Form B is more like a defensive stance. An area-effect strike as a 5'-25' cloud, with, say, a minute duration and some constraint that the effect ends if I leave the cloud. I'm not sure if that'd need to be paired with some form of immunity.
Then, there are more traditional auras. Drain/Fatigue/Paralysis/Stun Aura. If anyone touches me, they're overwhelmed by the battle aura, and that could be more subtle.
Form D would take the form of a more aggressive aura. Just slap Homing on a strike a couple times, and the aura pursues the enemy until the attack connects.
Multiple forms at once could overlap, like the ki cloud and the homing fists, though that could be very costly.
Other powers I'm considering include a rank in Speed, Slow Fall, some form of accute Blindsense, a one-rank speed-based Teleport ability a la Shunpo, a rank in Super-strength (maybe), possibly some kind of meditative trance represented by Boost, and some standard Protection (probably with that maxed impervious).
