Suggested by Destroyer The Rhedosaurus will take down Gigantosaurus in much the same way it’s been taking down all of the other monsters who are after him. There just is no beating this guy. The Rhedosaurus is still one of the most deadly adversaries that we’ve ever seen and while the Gigantosaurus is fierce as well, they just aren’t in the same league. The Rhedosaurus will show him who the real king of the dinos is. Rhedosaurus wins.
