[5][6] Flatman debuted in West Coast Avengers #46 (July 1989), created by writer and artist John Byrne.

[21] Called the "2-D Avenger," his primary roles include long-ranged rescues and helping the team solve crimes with his extensive knowledge of fashion which he was reported to have "studied in college.

"[22] He was able to identify a woman's shoe and describe it in detail, and later rescued Weasel — referring to him as "sailor" — which led his team to question his sexuality.

[23] He revealed that he is in fact gay to his teammates, though he felt one-upped by Mr. Immortal being dubbed the pinnacle of human evolution (using the ambiguous phrase "Homo Supreme").

After Dinah Soar's death, Mr. Immortal suffered a nervous break down and Flatman stepped up as deputy leader.

Refusing to let the deaths of Dinah Soar and Grasshopper get him down, Flatman continued to try to persuade the team to further research Maelstrom's plans for universal destruction.

During the final battle, Big Bertha tried to save Flatman, who was seemingly sucked into a vortex created from Maelstrom's device.

With the GLA possessing a stronger resolve than ever, they returned to their headquarters only for Flatman to find that Tony Stark had sent a cease and desist notice ordering them to stop using the Avengers name.

[25] During the GLX-Mas Special, the team confronted Dr. Tannenbaum, who had released an army of living Christmas trees on the citizens of Wisconsin.

They were given a rescue mission to save Dionysus after he fell from Mount Olympus and was captured by A.I.M., who planned to use his powers to cause mental instability on all the superheroes they consider a threat.

He meets with Big Bertha and Doorman at a diner, while expressing concern that Mr. Immortal and Squirrel Girl haven't answered his call.

The team is later relocated to Detroit, Michigan where they meet a local girl named Pansy at their new headquarters, a factory owned by Tony Stark.

Upon getting arrested after a fight, Doorman escapes leaving Flatman and Bertha to deal with a young girl named Goodness Silva who can transform into a werewolf, attacking the police inside the station.

[35] After the team discovers that Dick Snerd shut them down, Mr. Immortal returns and goes on patrol with Flatman, while Bertha, Doorman and Good Boy go to Nain Rogue's bar to find clues.

[15] Returning to HQ, Mr. Immortal and Flatman learned that Bertha and Good Boy took Dick Snerd (Nain Rouge) hostage.

[37] Later, while fixing the Flatmobile, Flatman and Mr. Immortal receive a text message from Bertha, who was injured while fighting Dr. Nod and his squad.

After their victory, the team is visited by Deadpool who tells them that they've been fired and can no longer use the Avengers name, leaving them confused.

[40] He can withstand all forms of physical injury at a superhuman level, appear to be nearly invisible by standing at just the right angle and slip through very thin spaces, owing to his nearly two-dimensional body.
