Dr. Karla Sofen

A psychiatrist turned super-villain with a sharp mind and sharper ambitions, Dr. Karla Sofen made her catalog debut in Thunderbolts #54 in 2001, brought to life by Fabian Nicieza and artists Michael Barreiro and Patrick Zircher. She moves through the morally complicated corridors of Marvel's Modern Age alongside compelling figures like Melissa Gold, Jolt, and Citizen V — exactly the kind of charged company that makes the Thunderbolts corner of the Marvel Universe so endlessly fascinating. Her presence across Thunderbolts, Ms. Marvel, and Thunderbolts Classic speaks to a character with real staying power in Marvel's rogues' gallery, and for collectors drawn to complex, psychologically rich figures operating in shades of grey, Dr. Sofen is absolutely worth seeking out.
