Energy Blasts - After augmentations, his suit could fire powerful blasts in which he used against enemies and the JLA alike.
Fire Blasts - After augmentations, he used this against Martian Manhunter, knowing he was afraid and/or had a weakness to flames.
Gravitational Control - After augmentations, Mark used this against Flash to disable him and make him "fly" away.
Super-Strength - Although Mark had this before augmentations, it was greatly enhanced after. He could fight against the strongest DC Heroes, such as Wonder Woman and Superman.
Durability - The toughest blows from even Superman could not dent his suit, although when the Flash hit him, it temporarily disrupted his suit's functions. He did not show any sufficient damage to the suit until his suicide.
Flight - Before augmentations, Mark could only leap in strong bounds, but after augmentations, he could fly with power boots.
He was pretty tough but I don't remember specifics.
And he only appeared in this oneshot, though it was canon.
