Robin confronted Red X about his self-serving attitudes, while Red X kept taunting Robin about the one mistake which helped create him. Unimpressed and willing to make amends, Robin went after Chang himself, but almost ended up his victim as well. At the last moment, Red X saved Robin from certain death and aided him in freeing his teammates and bringing down Chang. When the Titans intended to do the same with him, he escaped by detonating a tube of Xenothium at their feet, though he had to leave his power belt in Robin's hands. Later on, Red X was seen as a recruit among the ranks of the Brotherhood of Evil. With his power belt replaced, he participated in a race initiated by Ding Dong Daddy for Robin's most prized possession, in order to sell it to the highest bidder. A bomb dropped by Daddy blew him off the road, but he was saved by Robin at the last instant. Because of this, and because he realized how desperate Robin was, Red X attacked the other villains participating in the race, thoroughly disabling their vehicles. His last target was a bus driven by Raven and Starfire, from which he withheld; he told the two girls "Tell Robin we're even ... for now", and disappeared. Red X did not appear in the final confrontation with the Brotherhood afterward, implying he quit the organization. His current whereabouts and activities are unknown. Physically, Red X is an accomplished acrobat and martial arts fighter on par with Robin. In fact, their combat techniques are quite similar, giving weight to the common suspicion that both once had the same tutor or other allies (which would be Batman, Red Hood, Spoiler or potentially Wonder Girl and Slade Wilson). Red X's powers derive from his suit's belt. The belt relies on power from a (possibly artificial) element called Xenothium. The suit is also fitted with an invisibility or cloaking device, and a teleportation device. The palms of his gloves can also form x-shaped manifestations which can act as shuriken, wrist-mounted blades, restraints (by constriction or adhesion), timed explosives, electric X's, instant openings, or any other conceivable function. Robin noted that he created Red X's main weapon systems as specific ways to beat each of his fellow Titans. Terror Titans (mentioned)
