Nebula

A ruthless space pirate and mercenary who claims to be the granddaughter of Thanos, Nebula rose to command her own crew of interstellar raiders. Whether her lineage is genuine or fabricated, she is a formidable military tactician and combatant who has led forces across the cosmos.

Few characters can claim a debut as unexpected as Nebula's — first appearing in The Transformers #7 in 1985, courtesy of creators Bob Budiansky and William Johnson, before carving out a lasting place in the Marvel cosmic universe. A Bronze Age original, she has endured across nearly four decades, racking up appearances alongside titanic figures like Thanos, Drax the Destroyer, Captain America, and Thor — genuinely rarefied company that speaks to her cosmic significance. Her deepest roots run through The Infinity Gauntlet, one of Marvel's most celebrated storylines, and she counts the Avengers among her affiliations — a remarkable trajectory for a character whose catalog journey began in such an unlikely place. For fans of Marvel's grand cosmic drama, Nebula is a figure well worth seeking out.
