Javelin

A villain sharp enough to earn a spot in DC's Who's Who — the ultimate roll call of the universe — Javelin made his mark in the Copper Age as one of those deliciously dangerous adversaries who populated the rogues' galleries of DC's greatest heroes. Debuting in 1986 thanks to Len Wein, he's the kind of character who turns up in the thick of things, sharing pages with heavy hitters like Green Lantern, Batman, Black Canary, Supergirl, and The Flash — elite company that speaks to his place in the broader DC tapestry. His appearances across DC Universe: Legacies and Justice League International cement him as a genuine piece of DC history, the sort of colorful antagonist that makes back-issue diving such a rewarding adventure.
