All-star supes is so strong that a single punch would kill RKT . Whereas RKT is sweating out the stuff that All star supes has no weakness against. Magic.
Evidently i say RKT takes it with a quick flash of his S-T-F-F-Y-B vision.
That's why we still have Galactus, but no weakness against Kryptonite? What the hell? Are they trying to make Jesus? We might as well say Pre-Crisis Superman, because that's what he is. Mr. Super-Weaving.
Heap loads of super strength and speed is pretty much all it is though. That's not much of a boost compared to Thor getting a load of magical powers and the Odinforce.
Come on now. He gained the wisdom to use the Odinforce perfectly and a ton of magical powers putting him at the top tier of the skyfather food chain. Compare that to Superman moving planets.
RKT is a elder god level, he killed a skyfather being in Mangog with a gesture, you think RKT will do to All-star superman. RKT has 100%control of the Odinforce and Rune Magic and Arcane wisdom and with his hammer and his father spear Gungiar that's to much raw power even for All-star superman to fight with.
I actually have really enjoyed all-star superman thus far. The idea that he has a limit to his power is something we don't see with current. Sure he's now immune to kryptonite radiation but he's also dying from all the power contained in his body right now. I'm unfamiliar with different versions of thor so I don't really know what to say about this fight. I don't know how much power he has. But unless it's as ridiculous as all-stars 300-quintillion ton strength it won't be an easy fight.
