@The_Mayhem_Theory: Amazo seemed to be immune from great physical harm, and BFR'd an entire planet into another dimension easily and brought it back with just a thought.
@The_Mayhem_Theory: Considering the entire JLA and dozens of GL's or the guardians didnt even slow him down.
As much as I concur on these responses, we also have to acknowledge the fact that the DC Universe isn't as similar to the Marvel Universe. Absorbing Man was able to replicate Sentry's powers, yet Sentry completely warped him. That thought alone leads me to believe that Amazo, if he were to come across Sentry, would get his arse handed to him. Granted, Amazo knows how to use his abilities to their full potential, I just don't see him having the same experience level with them. I could be wrong here, but isn't Amazo somewhat shy on experience when first absorbing said abilities?
No not this Amazo, he evolved throughout his travels in the galaxies and grew to be very smart.
You guys know that Superman can phase throught attacks, right? He saved the whole Omniverse this way. It's not only about defeating Kryptonians. It's about defeating bunch of people who are incredibly intelligent, able to make the Phantom Zone, Doomsday and someone as annoying as Brainiac. People often argue that Zod is equal to Superman. Then if he is, he can take out what Superman can. What feats of invulnerability does Superman have? Surviving a blast equal to 52 Supernova while weakened by Red sun radiation, survive the blast of Imperiex Prime, a blast that killed Doomsay, isn't knocked out by an explosion equal to one million nuclear warhead, etc. I doubt the power of Galactus is equal to 52 Supernova. We're not talking about a Full Fed Galactus. Do you honestly believe that Kryptonians would just stay in the blast and not do anything to dodge it? Superman has access to Torquasm Vo and Rao as well. With Torquasm Vo, he was able to beat Dominus, a reality warper who managed to beat Kismet (Eternity of DC), at his own game. Superman was able to forge his own reality and bring Dominus everywhere he wanted to. He forced Dominus to face him as Kingdom Come Superman and even Superman One Million. Do you think Silver Surfer could survive the Heat Vision of every Kryptonians? God, Silver Surfer has showed himself really weak to physical attacks before. We're not talking about 50 Kryptonians. They are more then that. And Red Sun doesn't depower Kryptonians instantly. Proof? Superman traveled inside RAO, a red sun that was surrounded by Kryptonite and he even took out a blast of heat vision from Superboy Prime. They then crashed landed on Mogo. Wasn't Beta Ray Bill able to crack the armor of Galactus once?
Krypton dies, Galactus takes a Super-Dump afterward in an abandoned galaxy
