First version is called Legacy. He has his blasting powers and stuff, but no cosmic awareness and no versatility. This is the version that fought SS and Tyrant.
After that was his plain old Cap. Marvel form. He had cosmic awareness and a bit more versatility but was still mainly just a blaster. Significantly above Legacy, he fought alongside SS on a few occasions. He has some other cool feats, but I haven't really read comics from this era. People might remember him as being the guy Thanos sought for help against Walker.
After that he went insane, which was because his cosmic awareness was supercharged. He could pretty much do anything he wanted, was very versatile, did Time manip/Matter manip plenty of times. Fought King Thor. Helped restart the universe. Lots of good feats that I think are clearly trans.
Then he wasn't insane but still had access to all that power. He looked like his second version but with a white outfit instead of red. He could do anything insane genis could but chose not to because of the threat of insanity. He had some really awesome time manipulation feats here and good time travel. His power was shown to be able to kill the combined armadas of Kree, Skrull, and Shiar empires with a mere thought, if he had enough experience. This is another feat that makes me think that on a pure power basis he is clearly trans. Took on Ely who could destroy five solar systems at once.
Then there was Photon. I don't really count him because he was using an outside power source here instead of his own powers. This is the thunderbolts version. Zemo killed him. Again I don't think this is representative of Genis because none of his feats here were using his own power.
