Jennifer Takeda

Jennifer Takeda, known as Hazmat, is a teenager who developed the uncontrollable ability to emit toxic radiation from her body, forcing her into a containment suit and making normal human contact impossible. Her dangerous condition drew the attention of the Avengers, who recruited her into their Academy program.

Jennifer Takeda made her entrance into the Marvel Universe in 2010's Avengers Academy #3, a Modern Age debut crafted by the formidable team of Christos Gage, Ed Brubaker, and Mike McKone — strong creative pedigree for a character arriving in one of that era's most compelling corners of Marvel storytelling. She's built up a presence across Avengers Academy, Captain Marvel, and Avengers, sharing pages with a fascinating roster that includes Hazmat, Mettle, Finesse, and Jeanne Foucault — the kind of company that signals she's embedded in the texture of contemporary Marvel rather than hovering at its edges. With a key issue already to her name and appearances stretching across fourteen years through 2024, Jennifer has proven herself a figure with genuine staying power in the Modern Age landscape. If you're drawn to the generation of Marvel characters who came of age in the 2010s and have quietly endured, she's absolutely worth tracking down.
