Nova is one of the strongest Marvel heroes in existence. I consider him to actually be more powerful than the well known heavy hitters like Thor, Hulk, Apocalypse, Rogue, dare I say Thanos? He has the speed to keep up with his power, which is what truly makes him a deadly force. That being said, I feel like he will have met his match against Ryu. Ryu’s strength and speed will allow him to have an even fight with Nova and both of them have powerful projectiles. It would be a tough fight to the end, but I see Ryu being able to take this round in the end with his demonic abilities. His stamina is nearly limitless! Had Ryu not appeared in Asura’s Wrath, this would be a clear win for Nova, but that game did change things. Ryu wins.
