Sojourner Mullein

Sojourner 'Jo' Mullein is a former New York City police officer who was recruited by the Green Lantern Corps and assigned to protect a distant, isolated sector of space called the City Enduring, wielding a unique power ring that works differently from standard Green Lantern rings.

Sojourner Mullein made her entrance into the DC Universe in 2020, debuted by the acclaimed team of Peter J. Tomasi and Doug Mahnke in Detective Comics #1015 — a Modern Age arrival who wasted no time finding herself in extraordinary company. Her catalog appearances span Detective Comics, Batgirl, and Supergirl, meaning she's moved through some of DC's most compelling corners of storytelling, sharing pages with titans like Batman, Superman, and Green Lantern. With only twenty catalog appearances to her name so far, she remains a figure with real discovery potential — the kind of character a sharp reader finds early and champions loudly. If you're drawn to Modern Age DC and love a character still writing her legend, Sojourner Mullein is absolutely worth your attention.
