I don't want to be a damper on your party but... There was a slight expectation in me that this was supposed to be around street-level characters and not city-busters? We already have a dragon and then basically a god who wants to come to the party, so we'd have two people easily trampling buildings easily like whilly-nilly. I'm not sure what but I dont think we're facing Galactus anytime soon or an alien invasion so both of those characters are overpowered for the situation we're in. The only feasible character that has the slightest chance of winning is Caden's augmented character, due to his various enhancements and still he'll lose almost 10/10 times even against base form of Lancelot and not to mention the God Fist character. The rest of the cast is useless in fighting the other two even with everyone pitted against them. 

Either way, my two cents on the things but yeah. Rare metals, emotional limiters and anything else wouldn't be able to do anything to stop even 500 lbs of force coming onto your body and completely decimating you with Mach 1+ speed almost instantaneously. Too fast to catch and too strong to hold down for any physical limiters to accurately be used either way. Comparing our strongest character from the two, Poly's character couldn't take that and Yin's character's rapid regeneration wouldn't help with his whole body decimated in one blow. If we are going to accept two characters of this caliber, I'm going to reconsider about my character abilities so they don't become collateral in just the mere shock waves.
