As far as fighting abilities go, Superman is trained in the Kryptonian fighting arts of Torquasm-Rao and Torquasm-Vo, and his uppercut can knock someone’s teeth back up through their eyeballs.
Superman boasts just about every golden-era superhero ability.
He’s also learned from the teachings of fellow heroes like Batman and Wonder Woman.
He has super-speed, heat vision, x-ray vision, ice breath, and is also able to keep his identity a secret with a pair of glasses and a fumbling-about persona.
