Sister Hammer

Sister Hammer is a martial-arts warrior who operates in Shang-Chi's world alongside fellow fighters Sister Dagger and Brother Sabre, all connected to the legacy of the legendary Zheng Zu in Marvel's martial arts mythology.

A striking presence in Marvel's Modern Age, Sister Hammer burst onto the scene in 2020's Shang-Chi #1, brought to life by the acclaimed creative team of Gene Luen Yang, Dike Ruan, and Philip Tan. She moves through a world populated by formidable figures — Shang-Chi himself, the legendary Zheng Zu, and fellow warriors Sister Dagger and Brother Sabre among them — making her a character deeply embedded in this richly imagined corner of Marvel's martial arts mythology. Though her catalog appearances are select rather than sprawling, every one of them lands within Gene Luen Yang's celebrated run, which means she's part of some genuinely essential modern comics reading. For fans who've discovered or rediscovered Shang-Chi through Yang's thoughtful, action-charged storytelling, Sister Hammer is exactly the kind of compelling supporting figure that makes this series worth savoring.
