Dirty Bubble

In "The New Adventures of Mermaid Man and Barnacle Boy", The Dirty Bubble is their Number 1 most arch nemesis. His powers are to trap Mermaidman and Barnacleboy by his Surface Tension. Spongebob defeats him in this fiends first appearence with a pencil. (Duh!) He is voiced by Charles N. Riley in his first apperience, and then he decided to quit the show, making Tom Kenny the current voice of this fiend since "Mermaid Man and Barnacle Boy II"
