Current Quasar takes it, 6/10. Thor would get his A$$ handed to him here. Not easily, but he would go down. Genis is one of my favorite characters, but I think the Quantum Bands are just too powerful. Add the fact Quasar's immortal, and has super strength/durability thanks to the Quantum energy bolstering his strength and metabolism. Really similar to Genis, but Quasar is a bit more experienced. Quasar wins. Oh, all 3 of these guys could take Hal Jordan. HAHAHAHA!!!
Actually it could very well be the opposite. Quasar could absorb the Nega Bands and it's untold power into the Quantum Bands. He did just that to the cosmic entity known as Ego. He absorbed that big planet thing into his Quantum Bands. It will be very close, but 6/10 Quasar takes it imo. I love Genis, but he's a little short of experience going against Quasar. But could go either way.
genis kicked every asgardian's ass simultaneously, he also kicked KING THOR'S ASS!!!!! thor is no match for him, quasar wasnt really too powerful until i heard that he absorbed ego, either that was bullshit writing or he was powered up somehow, cause that would put quasar in the same league as sentry{even higher than galactus}
Quasar's powers are limited cause he must use most of them to keep the Ego-Spore into his body.
Genis powers are LIMITLESS, he's hella powerful, and even his evil version from an alt future showed he can be even more than his actual state, he can just absorb the constructs then blast Quasar to death, Genis Speed and reaction time are superhuman, plus he was able to stomp King Thor, he's a force to reckon with, not to forget Quasar is a good guy, Genis is half mad and half bastard
