Atomic Flounder

The Atomic Flounder is a retired enemy of Mermaid Man and Barnacle Boy. He is only mentioned by Mermaid Man in the video game that Prawn appears in. He also appears in "Mermaid Man and Barnacle Boy II." He may be related to Flatts the Flounder, although it is not certain. His atomic breath is a parody of Godzilla's popular atomic breath which he uses against monster foes. At first it seems that he is a very string and tough villan, because he stands up to Mermaid Man & Barnacle Boy. But, he is taken out by a double punch from the two heros. He was voiced by Carlos Alazraqui

Atomic Flounder(Elderly)

Here the Atomic Flounder is a lot older. He seems that he was a fake character from the show. But being told the stories, Spongebob attacks the elderly Atomic Flounder and the flounder screams for help. The heroes come and get Spongebob off of him. The flounder could not beleve that Spongebob had said that he could snap back just like that."If I weren't retired I AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!"-Atomic Flounder he blasted his Atomic Breath and burned Barnacle Boy's face to a crisp(because Mermaid Man ducked).
