Karla Sofen

An ambitious and manipulative psychiatrist, Dr. Karla Sofen used her psychological expertise to coerce the original Moonstone into willingly surrendering the alien Kree gravity stone he carried, allowing her to absorb it into her own body and gain incredible superhuman powers.

Karla Sofen has been one of Marvel's most compellingly complex figures since Roger Stern and Sal Buscema introduced her in The Incredible Hulk #231 back in 1979 — a Bronze Age debut that launched nearly five decades of appearances across 259 catalog entries and 12 collector-recognized key issues. She's most deeply woven into the fabric of Thunderbolts, Dark Avengers, and Ms. Marvel, series that thrive on moral ambiguity and shifting allegiances, and she keeps genuinely electrifying company — sharing pages with Spider-Man, Hawkeye, Wolverine, and Ms. Marvel herself. Whether you're a longtime reader who's tracked her journey across the Bronze Age and beyond or a newer fan drawn in by the darker corners of the Marvel Universe, Karla Sofen is exactly the kind of layered, enduring character who rewards every issue you hunt down.
