"Red X works alone." - Red X to the Titans.
Red X (voiced by Scott Menville) is a masked anti-hero and thief.
Robin once disguised himself as Red X to get closer to Slade. But he feared that if his teammates knew about his plans, they wouldn't play their parts convincingly. So he decided not to tell them. But his plan backfired. So Robin decided never to use the Red X suit again.
But eventually, a unknown culprit managed to get the suit and become the new Red X. However, he actually got a box that belonged to Robin back for him, but returned to his life of crime, never to be seen again until now. He even showed it when he saved Beast Boy from an oncoming train.
- Red X will become Jeffrey and Jaden's enemy in Jeffrey, Jaden & Friends' Storm Adventures of Teen Titans. However, due to the fact that he's an anti-hero, he'll also become a occasional ally to them.
- Red X doesn't serve Set or any other villains since he perfers to work alone.
- Red X also doesn't do Bounty Hunter work because, he may be a villain, but he's not a delivery boy.
- In Jeffrey, Jaden & Friends' Storm Adventures: War of the Chaos Emeralds, Red X gets himself involved in the war for the Chaos Emeralds. He forms an alliance with Catwoman in order to survive the war and try getting the Chaos Emeralds for themselves.
- Red X will guest star in Jeffrey, Jaden, Hiccup & Friends' Storm Adventures of Spider-Man: Homecoming.
