Justice

Few Marvel heroes can claim they crashed into the spotlight via a Slapstick comic — but that's exactly how Justice made their memorable entrance in 1993, courtesy of Len Kaminski and James Fry. A true child of the Copper/Modern Age, Justice has since grown into a genuine Marvel institution, racking up 139 catalog appearances across more than three decades and earning six collector-significant key issues along the way. Their home turf runs through the pages of Avengers, Avengers: The Initiative, and Avengers Assemble, where they share adventures with heavy hitters like Captain America, Iron Man, and Firestar's own Angelica Jones — serious company that speaks to just how deeply woven into Marvel's heroic fabric this character has become. If you're tracing the evolution of Marvel's street-level-to-cosmic ambitions from the '90s onward, Justice is a throughline absolutely worth following.
