Superman vs. Pyron
I thot why the hell not and decided to make this thread. Pyron is one of the top tiers from the Darkstalker games from Capcom and is the guy in my sig and avy. He has also been in comics so he is not against rules. He basically is a Cosmic Fire Elemental alien who eats planets. He is able to change his size from as small as a man to a size dwarfing the Andromeda galaxy, tho at that size, I think his attacks would be only limited to physical(this is just a guess, but it makes sense) since he is just expanding his physical form, whereas human sized all that power is probably compacted to his smaller form and is able to release it more effectively. Also, he can change shape in many ways that gives him advantages in battle. He is able to create min suns(tho those would only give Supes more power) that can level cities with ease as well. It was also stated that his power is only limited by his imagination(whatever that means). I have a vid of the Darkstalkers OVA which I believe shows canon abilities, which consists of Pyron toying with many characters and beating their asses(with the exception of Demitri, they were fighting on pretty even terms, tho Demitri is also the guy that survived an attack that literally at full power can shatter a dimension(it was fired at him at half power by Belial). Also note that the fights are not done as fast as they should be, as Pyron travels from planet to planet and eats them, and it takes little time for him to traverse Solar Systems. Here is the vid(Warning, if you hate Slipknot turn off your computer's volume):
The rules for the fight are that Pyron cannot use his planet eating abilities and is limited to human sized form. I personally think Pyron still wins, but I want to know what you think. Also, this is a link that tells all of Pyron's abilities:
