The Valentine sisters from 'Skullgirls' have such a fascinating and tragic backstory that really sticks with me. Nancy and Nadia Valentine were orphaned young and taken in by the infamous crime boss Lorenzo Medici. Nancy, the elder sister, became a ruthless enforcer for the Medici mafia, while Nadia was groomed to be a perfect lady—until she rebelled and became the vigilante 'Ms. Fortune.' Their dynamic is heartbreaking; Nancy's loyalty to the Medicis eventually pits her against Nadia, who wants to tear the organization down. The game doesn't spoon-feed their history, but the hints in their dialogue and lore drops paint a picture of love twisted by desperation and duty.
What gets me is how Nadia's transformation into a cyborg catgirl (yeah, it's wild) mirrors her fractured identity—part warrior, part survivor, forever torn between her past and her vengeance. Meanwhile, Nancy's 'Double' persona as a shapeshifting horror reflects her own loss of humanity in service to power. It's a story about family bonds breaking under the weight of corruption, and it adds so much depth to their flashy fighting moves.
