White Rabbit (Jaina Hudson)

Warhawk (Rex Stewart) is a character created for the DC Animated Universe, voiced by Peter Onorati. In the Batman Beyond episode "The Call", Warhawk is introduced as a member of Justice League Unlimited (the Justice League of the future) alongside Big Barda, Green Lantern (Kai-Ro), and Aquagirl (Mareena). He is initially at odds with Batman (Terry McGinnis) because Superman had recruited him into the team without the rest of the League's consent. After Batman proves himself to be a competent and trustworthy member against Starro, Warhawk's attitude shifts from reluctant ally to devoted teammate.

Warhawk appears in the Justice League Unlimited episode "The Once and Future Thing, Part Two: Time Warped", where he is revealed to be the son of Green Lantern (John Stewart) and Shayera Hol. In the third-season episode "Ancient History", Stewart informs Hol of Warhawk's existence. Despite still loving Hol, Stewart decides to stay with Vixen, refusing to let his knowledge of the future affect the present.
