Faust (Japanese: ファウスト Hepburn: Fausuto) is a character in Arc System Works's Guilty Gear video game series. He first appeared in the 1998 video game Guilty Gear as Dr. Baldhead (Dr.ボルドヘッド Dokutā Borudoheddo). In the series, he is a doctor who becomes a murderer after the death of a girl in one of his surgeries. After killing scores of people and being imprisoned, Faust is given a second chance after the first tournament. He decides to commit suicide, but he learns the girl's death was actually caused by a third party. Donning a bag on his head and taking his oversized scalpel, Faust seeks out the truth about the girl's death while dedicating himself to saving lives again.
His unpaired appearance and personality has led to different commentaries by video game reviewers; while a reviewer described him as "iconic", another critic called Faust "goofy". Faust was also noted to be a good fighting game character while his moves received both praise and criticism.
