Suggested by Destroyer Cerebrus isn’t a very well known character at all, but he did give Ironman a pretty good fight back in the day. He may be able to fire off a few good shots at The BioLizard, but it’s not as if the attacks will deal any damage so he isn’t a threat. The BioLizard can just step on Cerebrus and that would be the end of the match. The difference in sheer power and size is absolutely massive. The poor villain never even stood a chance. The BioLizard wins.
