Actually, I think I'll side with Wonder Woman here. Yes if she went toe-to-toe with him she'd be splattered, but she doesn't have to.
She also has the Godwave, which, from what I've been told, is capable of harming Skyfathers, which are much higher on the totem pole than Hulk.
A FTL rush with the Godwave should get her the win, but she'd have to do it fast.
Hulk. Just Hulk. He's just gonna keep coming back angrier and stronger. If this is World War Hulk, then Wonder Woman doesn't have a chance at all.
And I still don't think Sentry has the power of 100 suns as he is claimed to have, or at least he didn't show any evidence of that. Could be mistaken on that but whatever. Sentry is still a whiny, schizophranic bastard.
That's a no limits fallacy. He won't be coming back from shots capable of harming Skyfathers.
And regarding that million suns thing it's probably a hyperbole/call sign.
