The Atomic Flounder just might be my favorite Mermaid Man and Barnacle Boy villain. I know that he's retired now and he was a pretty minor villain, I like that the threat he makes is that if he wasn't retired, he would "BLAAAAHHHHHHHH" *shoots radioactive stuff out of his mouth* do that. Also, all the flounders in Spongebob are great. But that would actually be kind of a cool ability to have. Either atomic breath like his, or fire or ice breath, or laser breath or something like that. I don't know, any of those would be pretty cool.
