Warhawk src

Rex Stewart is the hero Warhawk, a member of the Justice League Unlimited. He is the son of John Stewart and Shayera Hol. Named after John's former marine buddy Rex Mason.


Rex Stewart was raised in the village of Zambesi. At the age of eighteen, he created the Warhawk Armor and travelled to Gordanian-controlled Thanagar. Allying himself with an underground resistance, he supplied them with Nth Metal to act as prosthetics and they were able to retake the planet. Unfortunately, the Thanagarians looked down on Rex for being only half-Thanagarian. While the planet slowly became more accepting, Warhawk decided to return to Earth and eventually joined Justice League Unlimited.[1]

The Call

At first, Warhawk wasn't impressed when Superman brought Batman into the JLU to seek out who had ambushed Micron. This only worsened when Batman could only barely prevent an assault on Aquagirl. But Warhawk wasn't stupid - he knew that whoever betrayed the JLU, they would come after him at some point. Through remote-control, Warhawk operated his armor into battle and let the traitor destroy the armor.

Warhawk eventually helped Batman uncover the real traitor - a Starro-controlled Superman.[2]

Alternate Timeline

In an alternate timeline in the future created by Chronos, Warhawk, Static, Batman (Terry McGinnis), and Bruce Wayne were the only JLU members that survived. The JLU had to use an abandoned Hamilton Hill High School as their new headquarters, because both the Metro Tower and Batcave were destroyed.

When Justice League members John Stewart, Batman and Wonder Woman traveled to the future to stop Chronos, the JLU saved them from an ambush by the Jokerz. After they escaped, they went back to headquarters where Rex introduced himself as the son of Stewart and Shayera Hol.

These events were erased when John and Batman reversed Chronos' effect in the timestream, but the memory of his son still troubled the Lantern.[citation needed]

  • Armor: Warhawk wore armor of polynized-aluminum steel, that could be expanded to cover his entire body.
  • Nth Metal Wings: Because he was only half-Thanagarian, Warhawk did not possess their trademark wings. But he adopted the hawk as his symbol nonetheless, and made himself wings out of Nth Metal.
