whoa whoa whoa guys, hold up your missing something, maybe I didn't explain it well.


So if something kinetic hit him, something simple the weakest blast you could think of. He would only be able to use the opposite ability to that extent, anything above that is free game, but then you would have to go higherto hit him again, an again. You can beat him, especially since he's basically a normal human being. Even though you can't hit him your power you could probably stab him, or beat him up. 


Also there is the bonus of him having to figure out what his opposite ability is. 

another way you could beat this power is by using your power indirectly, in James' case he can use his ability to up his strength, that doesn't count as using your power against him. That's just you enhancing your body, more of an internal abilitym and for that he would need your DNA.

Also if he were to attack James with a ball charged with energy and he took it away, it would still hurt, it's not like he doesn't feel anything charged with kinetics  being it just wouldn't have that extra kick that James' power gives him.
