Red X was initially a villainous identity Robin assumed in an attempt to get closer to the villain Slade. After being outsmarted by Slade and nearly getting himself killed, Robin locked up the Red X suit, vowing never to use it again.
Some time later, however, the suit came into the possession of an unknown culprit. This new Red X had intended to use the suit for his own financial gain, but because the chemical Xenothium powering the suit was nearly exhausted, Red X stole a Xenothium scanner to hunt for more of the substance.
