His form is that of a giant, dirty bubble, hence his name. He can capture an object by landing over it and sucking it in.
In the episode "Mermaid Man and Barnacle Boy II," he suddenly appears and attacks Mermaid Man and Barnacle Boy, trapping them inside him. When SpongeBob emerges from the diner, having found the Mermaid Man and Barnacle Boy theme song on the jukebox, he defeats the Dirty Bubble by popping him with a pencil which he claims was for the Dirty Bubble to sign his autograph with. Dirty Bubble returns (it is unknown how), alongside Man Ray, alive and well, in "Mermaid Man and Barnacle Boy V." In the episode, Man Ray has teamed up with him to form an organization called E.V.I.L. (Every Villain Is Lemons). When Barnacle Boy tires of Mermaid Man treating him like a little kid, he joins the two, and commits crimes. In the end, Barnacle Boy returns to the good side, leaving Man Ray and Dirty Bubble disappointed. He is a champion at paddleball, as seen in "Have You Seen This Snail?." He also appears as the main antagonist of the episode "Patrick-Man" where he was disguised as Mable and even captures SpongeBob. He was defeated by Patrick. His name might be derived from an episode in an old TV show called "The Wild Wild West" with an episode being named "Night of the Deadly Bubble."
Powers and Abilities

As being a bubble, pointy objects are the Dirty Bubble's sole weakness.
1. SpongeBob SquarePants: The Yellow Avenger- SpongeBob accidentally puts the Dirty Bubble into a washing machine and he splits into multiple Dirty Bubbles. The Dirty Bubble later plans to end The "Yellow Avenger's" journey with the machine Jumbo Shrimp used in the third Act. He also plans to hit SpongeBob with other little Dirty Bubbles
In "Have You Seen This Snail?," the "Dirty Bubble Challenge" on the Mermaid Man and Barnacle Boy paddle ball set implies that the Dirty Bubble is able to hit a paddle ball the absurdly impossible number of 29,998,559,671,349 times in a row. It is extremely unlikely that this is true, especially since he has no hands and therefore no articulation or coordination to play paddle ball with. However, Patrick claims to have achieved the number in the challenge.
In 2007, his first voice actor, Charles Nelson Reilly passed away from complications of pneumonia.
At one point, he went to Cancun with the Killer Shrimp, as stated in "Mermaid Man and Barnacle Boy V".
In "Mermaid Man and Barnacle Boy V," it is shown that the Dirty Bubble can make a human hand with fingers as demonstrating when he pointed into a boat. This may be how he made the "Dirty Bubble Challenge."
Being a bubble, his sole weakness is pointed objects like pencils.
It has even became a running gag that in just about every episode he appears in so far, he gets defeated by getting poked by something sharp.
