Harry Osborn

The son of wealthy industrialist Norman Osborn, Harry grew up overshadowed by his demanding father and became Peter Parker's college roommate and closest friend. Eventually inheriting his father's Oscorp technology and the deadly Goblin formula, he took on the mantle of the Green Goblin.

Few supporting characters in Marvel history have cast as long a shadow as Harry Osborn, who stepped onto the page in The Amazing Spider-Man #31 back in 1965, brought to life by the legendary Silver Age partnership of Stan Lee and Steve Ditko. Over more than six decades and 342 catalog appearances — 20 of them recognized as key issues — Harry has proven himself one of the most enduring figures in Spider-Man's world, a constant presence across The Amazing Spider-Man, Ultimate Spider-Man, and beyond. He shares his story with some of Marvel's most iconic names: Gwen Stacy, Mary Jane Watson, Flash Thompson, J. Jonah Jameson, and the Green Goblin himself — company that speaks volumes about the dramatic weight Harry carries in every room he enters. If you're serious about Spider-Man's emotional core, Harry Osborn isn't a footnote — he's essential reading.
