Flatman was a former member of the Heroes of Wiki, but he turned to the dark side.
Flatman was a good person, but the dark side ensnared him in Issue #50. In a shocking turn of events, he used his global ban beam on Deathrock9 and killed him. He later nearly drove Koopa to commit suicide, then tried getting cosy with Wikia. However, even Wikia was disgusted by this, and began monitoring Flatman closely.
