In "You Got F'd in the A", Michael helps Stan's dance team out in an effort to be the biggest non-conformist of all by not even conforming to goth standards. He also suggests bringing Yao and a girl (who ends up being a Raisins Girl) into the group.
Michael reappears in "The Ungroundable", being mistaken for a Vampire kid. The Goth Kids kidnap Mike Makowski (the head Vampire Kid) and suggest ramming a stake through his heart, but end up sending him to Scottsdale, Arizona instead. Michael appears in "T.M.I." in the anger management class with several others. He may have a small penis, as he goes to an anger management class with other people who have anger issues due to their penis size.
In "Goth Kids 3: Dawn of the Posers", Michael, Pete, and Firkle go to the CPS agency in an attempt to report Henrietta's parents' child abuse for sending her to a disciplinary camp that turned her "emo". Later in the episode, his parents end up sending him to the same camp to help "make him normal."
The Goth Kids have collectively and individually engaged in numerous criminal offenses.
- Arson: In "The Ungroundable", Michael and the other Goth Kids set fire to Hot Topic, burning it to the ground.
- Attempted Murder / Kidnapping: In "The Ungroundable", he, with the Goth Kids, kidnap Mike Makowski, the leader of the South Park Vampire Society, with the intent of murdering him. After he admits he isn't a vampire, however, they change their minds and ship him off to Scottsdale, Arizona instead.
- Drug Abuse / Underage Smoking: Michael is frequently seen smoking cigarettes despite being only 11, in addition to abusing cough syrup to hallucinate.
- Hostage-Taking / Terrorism: In "T.M.I.", Michael participates in the Pissed Off and Angry Party's taking of hostages at the Fed-Ex offices.
- Treason / Sedition: In the Superhero Arc, they are shown to be part of the Cthulhu cult and supporting the eponymous monster's reign of terror. They later leave the cult, though, expressing dissatisfaction with the outcome.
In "You Got F'd in the A", Michael joins The South Park Diggities along with Stan, Mercedes, Yao, Jeffy and later Butters. The Diggities win the dance off against The Orange County Crew, but mainly due to Butters killing them accidentally.
Michael occasionally walks with a cane, however he is seen walking without it, including giving it to Stan. He is taller than the others and has curly black hair. His large nose is visible along with his ears, unlike most South Park kids.
Michael is possibly half-Asian, half-Caucasian because in "Goth Kids 3: Dawn of the Posers", it is revealed that he has an Asian mother and Caucasian father. Although, this could be his stepmother because in the episode "Raisins", he states "Love didn't work out for my mom and dad, so why should it work out for me?", suggesting that his biological parents are divorced.
