Teresa Vasquez

Teresa Vasquez slithered onto the Marvel scene in 1988, a Copper Age creation of the legendary Mark Gruenwald and Tom Morgan, debuting in the pages of Captain America #337 — itself a collector-significant key issue. As a member of the Serpent Society, she keeps genuinely dangerous company, sharing adventures with the likes of Fer-de-Lance, Puff Adder, and Rock Python. Her 34-year presence across Captain America, The Amazing Spider-Man, and Avengers by Jason Aaron speaks to a staying power that makes her a rewarding deep-cut discovery for any fan who loves the rich, sprawling texture of Marvel's villain landscape.
