Teddy Altman

Few characters have made a splash quite like Teddy Altman, who burst onto the Marvel scene in 2005's landmark Young Avengers #1 — one of the Modern Age's most celebrated debuts, brought to life by writer Allan Heinberg and artist Jim Cheung. Over more than two decades of publication, Teddy has proven himself a cornerstone of that beloved series and a fixture in major Marvel events like Avengers: The Children's Crusade, racking up 139 catalog appearances and an impressive nine key issues that collectors genuinely prize. He moves in rarefied company — sharing adventures with Billy Kaplan, Kate Bishop, and heavy-hitters like Captain America and Hawkeye — which tells you everything about the weight this character carries in the Marvel Universe. If you've ever wanted to follow a genuinely enduring Modern Age hero from the ground floor of a fan-favorite series, Teddy Altman is exactly the kind of character worth diving into.
