Kevin Masterson

Kevin Masterson is the young son of construction engineer Eric Masterson, who first appeared when his father became entangled in the world of Thor and Asgardian conflict. His presence in Eric's life shaped much of his father's heroic journey.

Introduced in the pages of Thor #399 back in 1989 by the celebrated team of Tom DeFalco and Ron Frenz, Kevin Masterson is a Marvel Copper Age figure whose story has quietly unfolded across more than two decades of comics. With 29 catalog appearances spread across Thor, Thunderstrike, and Avengers Next, he's a character whose longevity speaks for itself — and three of those appearances carry key-issue weight that collectors have taken notice of. He shares the page with heavy hitters like Thor, Steve Rogers, Spider-Girl, and both Eric Masterson and Thunderstrike, placing him squarely in some of Marvel's most dynamic corners, and making him well worth tracking down for anyone who loves digging into the richer, more personal layers behind the thunder.
