Suggested by Destroyer Copperhead isn’t the most powerful fighter and he will be going down here. The guy has some basic durability and slight strength but it’s not really something that will make a Kaiju nervous. As soon as Biollante starts powering up one of those acid energy blasts then it’s all over. There just isn’t much that Copperhead could really do to try and defend himself here and there is certainly no escape. Biollante wins.
