The enduring allure of the Teen Titans franchise has been reignited by DC, bringing to the forefront an enigmatic mystery that first emerged two decades ago. The beloved animated series remains a cornerstone of DC’s rich history in animation, artfully combining a family-friendly atmosphere with gripping narratives and action. While the show made necessary adaptations to its comic book origins—most notably the decision to refer to Deathstroke solely by his first name, Slade—it preserved the essence that makes the Teen Titans one of DC’s most compelling superhero teams.
In its effort to remain engaging, Teen Titans introduced fresh elements to its narrative landscape. A standout addition was the character Red X, who was adopted by several figures throughout the series. The complex storyline surrounding Red X has sparked considerable discussion among fans, partly due to its intriguing ambiguity. Now, nearly 20 years later, DC has confirmed that this captivating tale is gaining renewed attention with an upcoming release.
Unraveling the Mystery of Red X





Initially, the identity of Red X was relatively clear, as Robin employed the moniker and costume to infiltrate the schemes of Slade Wilson. However, the Red X suit reappeared, this time worn by a different character, leading to numerous theories about its true identity.
In the series, the enigma surrounding Red X is accentuated by a playful in-universe conspiracy board, hinting at various characters such as Jason Todd and a time-traveling Nightwing as potential identities. However, a definitive answer is never presented within the show. Years later, the nearest revelation came from a comedic Teen Titans short, where Beast Boy humorously unveils different characters beneath Red X’s mask, including Jason Todd, Speedy, and even Batman, only to discover that the ‘Red X’ was a robot bomb.
The theory suggesting that Red X is indeed Jason Todd persists, bolstered by visual similarities to Todd’s Red Hood persona and sharing combat skills akin to Robin’s, likely due to their shared training experiences. Yet, the multitude of possibilities keeps the intrigue alive as Red X resurfaces in contemporary media.
Red X Reappears in Harley Quinn Season 5

The upcoming season of Harley Quinn, set to debut on January 16, 2025, has generated excitement with its trailer, reintroducing a mix of familiar and new characters, including major figures like Brainiac. Notably, Red X’s inclusion has captivated fans, as he is seen confronting Harley, having used his X throwing stars to bind Damian and Bruce Wayne to a wall behind her.
This moment carries significant implications, especially considering Red X’s initial introduction predates Damian’s character in the comics. The potential dynamics between Harley Quinn and Red X open up intriguing narrative possibilities. Since the character was originally created for Teen Titans, the show may delve deeper into Red X’s storyline, possibly contrasting the thematic elements explored in both animated series.
Given the lengthy absence of Red X from mainstream story arcs—aside from his brief appearance in Teen Titans Go!—it seems the creators of Harley Quinn are poised to reinvigorate his character with intent and depth, raising the prospects for this narrative direction. However, it appears unlikely we will finally uncover the original Red X mystery, despite the reinvigorated focus on the character.
Speculating the Identity of Harley Quinn’s Red X





The narrative of season 4 showcased a dramatic revival of Nightwing, resurrected by Talia Al Ghul using a Lazarus Pit after Harley Quinn inadvertently killed him while sleepwalking. Immediately following his return, Nightwing’s furious quest for Harley hints that he might assume the guise of Red X to hunt her down, operating incognito and potentially deviating from his typical heroic behavior in pursuit of vengeance—echoing themes from his time as Robin in the Teen Titans.
This development propels Harley Quinn season 5 into intriguing narrative territory, as Harley must grapple with the repercussions of her actions while contending with Nightwing’s belief that she harbors villainous intentions. By following this trajectory, the series may bypass the enigma of who donned the Red X suit after Robin abandoned it, seemingly reiterating the storyline of Dick Grayson stepping into the role for undercover purposes rather than suggesting a different successor like Jason Todd.
