Reactron

Reactron is a DC villain with ties to the Doom Patrol's corner of the universe, dangerous enough to be catalogued in DC's official Who's Who reference series. His connections to Robotman and the Doom Patrol place him squarely in DC's science-gone-wrong tradition.

A DC villain who made his entrance in 1986's Who's Who: The Definitive Directory of the DC Universe, Reactron emerged in the Copper Age as a dangerous enough presence to earn a spot in that landmark reference series — essentially DC's official roll call of its universe. His catalog footprint stretches across roughly two decades, with appearances alongside the likes of Robotman, Cliff Steele, and the Doom Patrol crowd, placing him firmly in the weird, wonderful corner of DC where science gone wrong and superhuman chaos tend to collide. With a Secret Origins Annual appearance on his résumé as well, Reactron is exactly the kind of deep-cut DC menace that rewards the curious collector willing to dig past the headliners.
