As much as I hate to say it.... there'd be virtually no contest. King Kong is probably around 20ft tall and I'd estimate he'd tip the scales at a lean 6tons. (a t-rex is roughly the same height/weight... which explains why those fights in the movie were so good. In the end, the combination of Kong's greater inteligence and love for blondie is what helped him win those battles.) He could have Einstein's brain and Romeo's heart... he'd still get his ass kicked by Godzilla. There's a reason the word 'GOD' is in its name. Freakin thing stands 120 meters tall and probably needs to go on jenny craig... various sites have him listed at a ridiculous 100,000 tons. (though, considering the biggest dinosaur is estimated at a mere 60 tons, that seems hard to believe.) whatever it is... it's a hell of a lot more than Kong. It wouldn't even be a fair fight. It would be like superman, as great as he is, fighting Voltron. This is a debate I've gotten into countless times... man of steel or not. He'd get stepped on like a bug. Now Voltron vs Godzilla... now we're talkin! My money's on V.... My money's always on V.
