Dr. Poison

A sinister presence lurking in the shadows of Wonder Woman's world, Dr. Poison made her DC debut in 1999, brought to life by Eric Luke and Matthew Clark in the pages of Wonder Woman — a Modern Age villain who has haunted Princess Diana across nearly two decades of adventures. With a name that says everything you need to know about her threat level, she's the kind of antagonist who makes even the most iconic hero's world feel genuinely dangerous. Her catalog appearances are rare, which only adds to her mystique — when Dr. Poison shows up, it matters.
