Steve decides to get back at Winston who tattled on him, by dressing up as a clown at a carnival and throwing a pie in Winston's face. As he is about to make his move, Winston and his girlfriend are stolen by other clowns and dragged into the Hall of Mirrors. Steve follows them, not wishing ill on Winston. He finds out that these clowns are going to make a full-scaled invasion on Earth. The clowns open up a portal to Dimension X and drag Winston and his girlfriend through. Steve follows after them.
Steve comes out of the portal as a blob, right into a scientists lab. The scientists makes a pseudo-molecular stabiltrode on some gloves, then slips them onto Steve. The scientist says when Steve went through the portal, "rather than having [his] atoms scattered throughout the universe, [he] was molecularly dis-discombobulated. This transformed him into a new form of matter-- a type of living unstable molecules called electroplasm, which is totally indestructible."
The scientist gives Steve two gloves, and tells Steve he needs to stop the evil ruler of this dimension . After he stops the ruler, he saves the Earthlings, and they all go back to Earth. When Steve gets back, his friend is waiting for him, and Steve tells him everything that happened. The friend says that Steve needs a name, and after several suggestions, Steve finally comes up with Slapstick.
Among Slapstick's adventures, he joins the New Warriors. He was not with the New Warriors when they blew up Stamford, Connecticut. After Civil War, he was one of the Initiative recruits (along with Cloud 9, Komodo, MVP, Ultragirl, Trauma, Thor Girl, Debrii Fields, Hardball, and Rage). When camp instructor Gauntlet continued to criticize and insult and mock the New Warriors for there mistake, Slapstick became so angry he ambushed Gauntlet and beat him almost to death (though Gauntlet survived and returned to work). After his assault, Slapstick painted "NW" (for New Warriors) across Gauntlet in Gauntlet's own blood.
No one ever discovered Slapstick's crime (because Secretary Henry Gyrich ended the investigation for fear it would uncover some of his shady experiments like the Scarlet Spiders); however, both Justice and Rage (of the Initiative) nearly got jailed, and Gauntlet insisted it was terrorist Ghost.
When Justice became so angry at the Initiative he formed a New Warriors team, Slapstick joined. Norman Osborn then made the New Warriors wanted criminals.
The New Warriors entered Camp Hammond to take the body of MVP, but found mad Thor cyborg-clone Ragnarok about to kill Gorilla Girl. The Initiative intervened and Slapstick (calling Ragnarok a "hippie" who needed to be introduced to "Whack-a-Mole") attacked Ragnarok. Ragnarok then easily defeated Slapstick. After the battle, Slapstick and the other New Warriors took MVP's body.
Commander Steve Rogers informs Prodigy of the unknown meteors that have fallen from the heavens and mass panic is on the horizon. Rogers asks Prodigy to gather heroes on a volunteer basis to help keep the peace and lead a new Initiative where there is no forced conscription or registration. Prodigy agrees to become the leader of the new Initiative and most of the former Initiative members including Slapstick gather in Washington DC.
Slapstick is a very joyful character. He is normally in a good mood, and also normally trying to lighten the mood, or cheer up his team mates. Most of the time though, his teammates find him more annoying, than funny.
Using his cartoon-like body, he is able to further enhance his looks, to appear more humorous. It's been noted that he can have an anger problem, if pushed too far.
When Steve first got his powers, he was told he needed to use them to fight crime. Steve was disappointed at this, and said he would rather play cruel tricks on people.
At Camp Hammond his drill instructor, Gauntlet, would constantly insult the New Warriors, Slapstick's old team. One day, Slapstick snapped and beat Gauntlet with a boot outside the base. However, he was never caught because Gauntlet chose not to blame him for the act, instead blaming the Ghost, and enemy on Iron Man.
