Ken Kurosawa: Once a skilled martial artist, Ken turned his trade as a street thug to work for gangs to help pay medical costs for his sister, Mariko. He is killed when a bomb explodes in his car, after switching to another gang for more money. He is compared to Al Simmons by Violator when he is not around, and is said to be extremely powerful by various characters. •
Mariko Kurosawa: After the death of her older brother, Ken, she became better from her illness and became a movie star after moving in with her aunt and uncle. She has been saved by Ken twice, although she doesn't know who her savior really is. She perceives her rescues as murders, because the people who were trying to kill her are people she knew. •
Clown/Violator: The Violator is a minion of Hell, and is loyal to Malebolgia, even though he swears to rebel against the devil. He leaves for New York to train Al Simmons part-way through the first manga, and returns smaller than his original size, due to Malebolgia's doing. •
Beezlebub: Preferring to be called "Bee", she is supposedly the little sister of Malebolgia. She acts as Ken's mentor during Violator's absence. She taunts both Ken and Violator almost every chance she gets, but has well-intended comments about Ken when he's not around. •
Malebolgia: Playing a very small role, the devil himself only makes one or two appearances in the manga. •
Tremor II: A nod to Al Simmons' own Tremor, Tremor II is a Los Angeles mob boss, infused with psychoplasm. He can only grunt or roar, until he melds with Terry Jones. •
Mikaela: A nod to Simmons' Angela, Mikaela is a freelance spawn-hunter. After Ken saves her from Violator, she wants to fight and kill him, claiming he stole her dignity. She flies away, wanting a rematch, until she shows up to save Ken from Scourge, a demon summoned from hell. •
Cheveyo: A mentor-like Spawn who has resisted Malebolgia for over five hundred years. Based upon the McFarlane toy, "Zombie Spawn". He thinks little of the minions of Hell and tries to destroy Kurosawa in their first meeting. He does not seem to have the familiar mask of Hellspawns, but instead has rotting, hanging flesh. •
Caleb: An 18th-Century pirate, Caleb is a vain, female Spawn. Her "need" for psychoplasm continues to grow as she gets older, as she sucks Spawns dry from their power. She intentionally tries to kill herself in a battle with Cheveyo. She also does not seem to wear a spawn's mask. She has distinct markings on her face, but her mouth is clearly visible. •
Mangler: A wolf-like Spawn. It is unknown what time period it is from, however, Cheveyo explains that "even animals don't escape from Malebolgia's doing". It can communicate with Kurosawa through telepathy. It does not wear a mask, but has markings near its eyes that seem to remind the reader of its status. •
Ells: A women who was jealous of Marko's scuess and was transformed by Violator into a demon until she was stopped by Ken. •
Toshio: A young man who becomes the bodyguard of Mariko who he develops feelings for. •
