Godzilla's got the size, the toughness, the strength, the atomic breath, the claws and teeth and the powerful tails, but he seems to lack the agility of Kong. If Kong were Godzilla's size, with his quickness, might, jumping ability and intelligence to grab anything handy to use in battle, he might manage to grab onto Godzilla's jaws to try to rib them apart, but then Godzilla would release his atomic breath to fry Kong's hands and catch his hair on fire and eventually consume him in the atomic fire. Kong would have a disadvantage if he fought Godzilla on dry land. If they were close to water, Kong might dive in it to rid himself of the fire but Godzilla was an expert swimmer as well, so he could swim fast and use his tail to smash Kong silly. The only way Kong might have a chance was to smash Godzilla with a part of a building or use something sharp to stab Godzilla with. He might go for Godzilla's eyes as well. Ha ha!
