Malchemical is a former member of Team Titanic, currently assigned to be team leader of Super Duper. Malchemical is a shape-shifter, who can alter his form, material and density in any way he chooses. He's been shown to be able to form metal objects (a bottle opener out of his thumb) as well as mimicking other people. MalChemical was kicked out of Team Tanic for impersonating the Team Leader for the purposes of having anal-sex with the leader's girlfriend.
Upon joining Super Duper , Malchemical showed his true anti-social tendencies by immediately taking to mocking his new teammates. Malchemical sees Super Duper as a sub par group of heroes, referring to them as retarded, and even constantly finding humor in Klanker's tourette outbursts. Team member Aunty Sis reported to Vought American that Malchemical is unwanted, drawing his ire as he is on probation and can't afford the bad publicity.
To get back at Aunty Sis for reporting him, Malchemical shapeshifts into another team member, Bobby Badoing, to have Aunty Sis confide in him about what makes her scared. Later on he uses this information to attack her. Hughie, who is on surveillance duty, hears all of this going on and ends up coming into the house and confronting Malchemical. The two get in a fight with Hughie losing badly, at this point Butcher comes in a saves Hughie and defeats Malchemical by setting him on fire while he was in gas form.
