Megaton Man (Trent Phloog) is a satirical superhero created by cartoonist Don Simpson.

A parody of the superhero genre, Megaton Man is a gigantically-muscled but dim-witted oaf who starred in Simpson's cheerfully absurd stories.

[1] Megaton Man is also the title of the creator-owned comic book series (published by Kitchen Sink Press beginning in 1984) Simpson wrote and drew, in which the character first appeared and starred.

The origins of Megaton Man's powers remain unknown, but the comic suggests two possibilities: he was either bitten by a radioactive frog, or he was the result of a military megasoldier program.

Yarn Man (AKA: Bing Gloom) was a member of the Megatropolis Quartet, but is now part of the VW Gang.

Unlike other members of the VW Gang, Yarn Man is the only other superhero who has his own sidekick (Kozmik Kat) and his own personal foe, Irving the Living Cactus (see below).

Donna Blank works as an activist in Detroit, Michigan, but when trouble strikes, she becomes The Phantom Jungle Girl.

A long-time ally of Megaton Man, she is also known for discovering the secret of Preston Percy and the Tomb Team.

Two anthropomorphic animals, Gower Goose and Kozmik Kat are the mascots to Megaton Man and his friends and members of the VW Gang.

A foe of the now-disbanded Megatropolis Quartet, Dr. Software plagued Megaton Man frequently, and still does following the disbanding of his rivals' "megahero" team.

Dr. Software was also responsible for the capture and holding to ransom of a newspaper journalist, Pamela Jointly (a possible reference to Lois Lane).

He was supposedly killed by an electric shock from X-Ray Boy in a ghost-town west of Detroit, Michigan, but was merely dehydrated.

When he was thrown into a river filled with chemically-polluted water, Irving was resurrected in a new anthropomorphic form, and has sworn revenge against the VW Gang.

The Tomb Team are supposedly killed after a battle with Megaton Man, Yarn Man and Cowboy Gorilla while en route to Detroit, Michigan, but interference by Count Dracula has led to the revival of the Frankenstein creations and revival attempts are being made on Dracula's Daughter.
