A self-styled, space vigilante who considers himself theEradicator of the scum of the universe”. He is armed with what he has named Time-blot, an apparatus containing the substance Chronoplasm, which erases its target and memory of it from time. He acquired the chronoplasm and its apparatus from the Soothsayer of the planet Maol.

The Janitor grew up poor on the planet The Root of Jōb and from his childhood wanted to be a police officer patrolling the skies, but he was rejected at the academy. He became obsessed after this and attacked a space police officer and stole his ship; using it himself to “fight crime” with his own brand of justice. The Janitor is prone to violent tantrums and he uses the Time-blot indiscriminately against anyone who offends him.
