Why is this turning into another thor vs superman fight. Superman beat thor unconcious. It's canon. Get over it. Nobody beats superman, ever. Besides, everyone knows that superman and thor's 2nd job is to get owned by weaker characters so that the writers can feel good about themselves. To answer the original question, namor isn't nearly in superman's class and get's speed blitzed into sushi. Wonderman goes "holy crap, I'm gonna die!" With good reason. Superman is stronger, faster, and shoots lasers out of his eyes. Wonderman ain't magic or the green stuff. Tough luck kid, maybe next time marvel writers can stop cloning superman. Have a nice trip, say hello to the sun again.
