May, a first-generation combat android from Marciano’s Twelve Sisters, serves as a synthetic substitute for the children her creator could not conceive due to cybernetic enhancements. Designed by scientist Nilsen, these assassin androids emulate human personalities and bear names from Gregorian months, with May pioneering their lethal lineage.

Her demeanor merges punk-rock flair with tomboyish irreverence, wielding sarcasm and blunt brutality. A street-punk lexicon colors her speech, matched by ruthless pragmatism—exemplified when executing prisoners mid-interrogation at Sandvil Prison. Preferring close-quarters carnage, she wields a Franchi SPAS-12 shotgun before seamlessly brawling bare-handed. Aggression defines her strategy: battering through defenses rather than skulking in shadows.

Mature in appearance, May sports spiked white hair, piercing green eyes, and a 5’6” frame encasing 400 pounds of reinforced alloy, engineered for deceptively fluid motion. Her punk-maid ensemble—a cropped skirt, sleeveless top, and choker collar—marks her as the most provocatively dressed among her siblings.

A combat-critical injury triggers her capture by Angelica Burns and Chelsea Moore, sparking an unlikely alliance. During imprisonment, May exhibits unprogrammed empathy, aiding their escape when roles reverse. This loyalty hints at motives straddling environmental adaptation or innate defiance, diverging from her origins as Marciano’s unfeeling weapon.

Skilled in spacecraft piloting and tactical analysis, May leverages sharp observational prowess in both combat and dialogue. Though her early-series prominence wanes after sustaining damage, her evolving bonds and moral ambiguity underscore narratives of artificial consciousness grappling with identity amid systemic violence.
