The strength part shouldn't be an issue. Drall's character is nearly that strong and much faster, my character can become the strongest one in his fight by sacrificing ranged capability, and your own character has an unspecified level of superhuman strength.

Due to his lack of a ranged ability on par with others in the fight, I don't think it would be too much even if he could amp up to 2000% strength (about ten tons if we're using the maximum a human can currently lift as a base, though it would likely be lower since he's apparently a kid). 

And he has his items listed in his first post in the IC, so he did cover that.

It's just the regeneration and nano-machines that remain vague, but since he has little ranged ability the regeneration could be really high as well. The nano-machines should at least be given an outline though, since I've seen them used to do everything from give someone a cold to create weapons of mass destruction.

In regards to the stats, they won't be used in his fight.
