Atomic Flounder

Atomic Flounder is a major recurring character from the world-famous Nickelodeon animated series, Spongebob Squarepants. Back in the day, Atomic Flounder was one of the most heinous adversaries of Mermaid Man and Barnacle Boy, on par with Man Ray and The Dirty Bubble. He was a mutant flounder who would fight them and try to take over the world.

Currently, Atomic Flounder is retired, much like the two superheroes who used to face him and now lives as a kind and timid old man, who does no wrong and is actually friends with his former rivals. However, he is not entirely redeemed, as he can still snap back to his old self at any time, which he has done on occasion.

In his current state, he is voiced by Carlos Alazraqui. His younger self is voiced by Dee Bradley Baker.

Biography
Atomic Flounder is the result of a nuclear test experiment, which went horribly wrong, which is what turned him into the mutated domination he is now. During his youth, Atomic Founder would tangle with Mermaid Man and Barnacle Boy and give the duo horrible doses of radiation. He became horrible enough of a villain to be accepted as the tertiary member of The Bad Guy Club For Villains, working alongside many other villainous greats, such as Man Ray, The Dirty Bubble, Jumbo Shrimp, and Sinister Slug.

Decades later, Atomic Flounder would eventually retire from being a supervillain and give up his evil ways to live his twilight years in peace, not unlike Mermaid Man and Barnacle Boy.

In "Mermaid Man and Barnacle Boy 2", Mermaid Man and Barnacle Boy were driving Spongebob around in the invisible boatmobile, when they passed by Atomic Flounder. Atomic Flounder was simply waiting at the bus stop, not doing anything wrong. From afar, Mermaid Man pointed Atomic Flounder out to Spongebob and told him stories about how he used to be one of their greatest foes and warned him that at any point, he could snap and become evil again. Spongebob took this as a sign that he should attack him and jumped right out of the boatmobile to do just that.

Spongebob beat up and assaulted the poor, defenseless old man without warning, leaving Atomic Flounder screaming for dear life. Mermaid Man and Barnacle Boy had to come in and stop him, telling Spongebob that he is no longer a threat. After Spongebob finally let up, Atomic Flounder yelled at Mermaid Man and Barnacle Boy, scolding them for allowing the little runt to attack him like that. He told them that if he wasn't retired he would use his radioactive belch on them to burn their flesh off. However, at the time he was saying this, he was so overcome by his rage, that he accidentally unleashed this exact power, incinerating Barnacle Boy's face to a crisp, before begrudgingly rummaging away in a huff.
