Riot

Riot is a villain who debuted in the pages of Supergirl, possessing the ability to split into multiple duplicates of himself, making him a dangerous and unpredictable adversary capable of overwhelming opponents through sheer numbers.

A creature of the Modern Age, Riot burst onto the DC scene in 2000 courtesy of the creative team of Peter David and Leonard Kirk in the pages of Supergirl, and has since carved out a niche across some of DC's most compelling corners — turning up in Batgirl and Superman alongside heavy-hitters like Batman, Batgirl, and Oracle. With a name like Riot, this character brings an unmistakable charge of chaos to every page they inhabit, and the eclectic company they keep — from the brooding streets of Gotham to the sunnier heroics of the Superman family — speaks to a versatility that kept them relevant across a solid thirteen-year span. Seven appearances may sound modest, but in a universe this vast, every encounter with Riot feels like a find worth celebrating for the dedicated collector.
