Leiko Wu

A highly skilled British intelligence operative working for MI6, Leiko Wu entered Shang-Chi's world as a seasoned field agent with expertise in espionage and hand-to-hand combat. Her dangerous work brought her into conflict with the criminal underworld and shadowy organizations threatening global security.

Leiko Wu made her entrance in the pages of Master of Kung Fu #33 in 1975, a Bronze Age debut courtesy of the formidable creative team of Doug Moench and Paul Gulacy, and she's been a compelling presence in Marvel's martial arts corner ever since. Over the course of roughly fifty years and 109 catalogued appearances — spanning Master of Kung Fu, Marvel Comics Presents, and Shang-Chi — she has proven herself one of the most enduring figures to emerge from that stylish, espionage-tinged era of Bronze Age storytelling. She keeps genuinely electric company: the pages she inhabits are populated by the likes of Clive Reston, Black Jack Tarr, Denis Nayland Smith, and the imposing Zheng Zu, giving her world a rich, globe-trotting intrigue that feels as much spy thriller as superhero saga. With a key collector's issue to her name and a publishing history that stretches into 2025, Leiko Wu is exactly the kind of character who rewards the fan willing to dig into Marvel's deeper catalog.
