Bitch, please. Simon is far more over the top than any Mary Sue could ever be. If he can't win a direct confrontation, he'd find a way -using pure willpower- to rip a hole into reality to reach the real world, find the server of fanfiction.net, and assimilate it into his mecha. Then he'd use something like probability-altering missiles to rewrite every fanfic written at any point in the past, present and future to make sure he's strong enough to defeat Mary Sue.
Simon has managed to form his hand into a drill though. If he can drill into something, he can assimilate it. And in the Anti-Spiral's dream world, he actually turned his body into Gurren Lagann
(though obviously, since that was the dream world, he may not be able to do it outside of it, though with spiral energy nothing is impossible), and Tengen Toppa Gurren Lagann
was basically created out of nothing. Also, even without that, this guy is probably crazy enough to be able to fix a snapped neck like it's a mere dislocated joint.
