Cool video, @novi_homines , thanks for posting it. He left a few things out but it seems mostly right. I had no idea that Aquaman could swim that fast. I know Namor is pretty fast, as he's made whirlpools and can make himself into a human drill, but apparently Aquaman is twice as fast.
NP. A lot of people forget, that Namor was Timely's answer to Superman. Until Marvel created the Hulk, he was their undisputed strongest character.
