From Sidekick to the Dark Knight: How Jensen Ackles Achieved Rare DC History by Playing Both Batman and Robin

Main Facts: A Unique DC Milestone
As DC fans and industry insiders continuously speculate about who will don the cowl next in James Gunn’s newly minted DC Universe (DCU)—with names constantly being thrown into the ring for the upcoming The Brave and the Bold—one fan-favorite contender already holds a remarkably exclusive place in comic book adaptation history.
Jensen Ackles, celebrated for his iconic television runs on Supernatural and The Boys (where he brilliantly portrayed the cynical, hyper-violent Captain America parody, Soldier Boy), stands as one of the very few actors in history to officially voice both Robin and Batman in official DC Comics adaptations.
While actors like Troy Baker have achieved a similar dual-hero feat across interactive gaming and animated features, Ackles’ journey through the sprawling mythos of Gotham City is uniquely poetic. He transitioned from playing Bruce Wayne’s greatest failure and tragic ward—Jason Todd, the second Robin who became the lethal vigilante Red Hood—to eventually stepping up as the Caped Crusader himself across multiple animated features in DC’s "Tomorrowverse" continuity.
Chronology: From the Streets of Gotham to the Cowl
2010: The Birth of the Red Hood
Ackles’ relationship with the DC Universe began over a decade ago when legendary voice director Andrea Romano and Warner Bros. Animation cast him in what would become a cult-classic animated feature: Batman: Under the Red Hood.

Adapting the infamous 1988 comic book arc A Death in the Family—where readers famously phoned in to vote for Jason Todd’s murder at the hands of the Joker—the film explored the resurrection of the fallen sidekick. Armed with firearms, military-grade tactics, and a burning desire for vengeance, the resurrected Jason Todd returned to Gotham not just to clean up its criminal underworld, but to force his former mentor, Batman (voiced by Bruce Greenwood), to break his one rule.
Romano famously noted that casting Ackles required someone who could capture both "better times and the worst of times." Ackles brought an edgy, cocky arrogance to the early scenes of the Red Hood terrorizing drug lords, which effortlessly bled into the raw, tear-soaked vulnerability of the film’s tragic climax.
2021–2024: Graduating to Batman and the "Tomorrowverse"
More than a decade after his poignant turn as Jason Todd, Ackles received a phone call from casting executives that initially caught him completely off guard.
When Warner Bros. Animation began assembling the voice cast for the ambitious, multi-film DC animated continuity known as the "Tomorrowverse"—kicking off with Superman: Man of Tomorrow in 2020—Ackles assumed he was being brought back to reprise his role as the Red Hood. Instead, he was offered the ultimate promotion.
As Ackles recalled in interviews regarding his casting as the Dark Knight in the two-part adaptation of Jeph Loeb and Tim Sale’s acclaimed graphic novel Batman: The Long Halloween:

"I come from a previous film where I voiced Red Hood. So when I got the call for this, I assumed I would be reprising that role… But then I realized I’d gotten the upgrade! I don’t think they even got the whole word ‘Batman’ out. They were like, ‘Bat-‘ and I was like, yes!"
Ackles’ gravelly, commanding baritone anchored Batman: The Long Halloween Parts One and Two, showcasing a younger, more methodical Bruce Wayne navigating a corrupt Gotham mob war. He subsequently reprised the role of Batman in several key Tomorrowverse installments, including Legion of Super-Heroes, Justice League: Warworld, and the epic three-part animated finale, Justice League: Crisis on Infinite Earths.
Supporting Data: The Elite Club of Dual-Hero Voice Actors
To understand how rare Jensen Ackles’ achievement is, one must examine the voice-acting landscape of DC Comics adaptations.
- The Rarity of Playing Hero and Sidekick: Very few actors cross the generational divide of the Batman family tree. Most voice actors are permanently cast in specific archetypes—either heroes, sidekicks, or villains.
- The Troy Baker Precedent: The most prominent peer in this exclusive club is prolific voice actor Troy Baker. Baker voiced Tim Drake (the third Robin) in the critically acclaimed video game Batman: Arkham City, before returning in the sequel Batman: Arkham Knight to voice Jason Todd/Red Hood. Baker later stepped into the boots of Bruce Wayne/Batman in projects like Batman: The Telltale Series. (Baker is also famously one of the few actors to voice both Batman and his arch-nemesis, the Joker, in the same cinematic universe).
- The Live-Action Fan Casting Factor: Following his tenure as Soldier Boy in Amazon Prime’s The Boys and his upcoming role in the prequel series Vought Rising, Ackles’ name has consistently topped fan-casting lists for James Gunn’s live-action DCU. Ironically, fans often point out that his dynamic with Jared Padalecki on Supernatural—where Ackles played the older, protective, brooding Dean Winchester—mirrored a dynamic akin to a live-action Batman and Dick Grayson.
Official Responses and Creative Insights
The enduring legacy of Ackles’ contributions to DC animation heavily relies on the meticulous direction of industry veterans like Andrea Romano. Speaking on the vocal demands of Batman: Under the Red Hood, Romano praised Ackles’ ability to marry bravado with profound emotional trauma.
"When you hear a great dramatic voiceover performance, you are listening to an actor actively fighting against the emotions they are feeling," Romano explained in behind-the-scenes featurettes. In the film’s climax, when Jason Todd confronts Batman and screams that his failure wasn’t failing to save him from the crowbar, but failing to kill the Joker in retaliation, Ackles delivered lines that redefined how mainstream audiences viewed the dynamic between Bruce Wayne and his wards.

Furthermore, Ackles has expressed profound affection for his time in the DC sandbox. While social media throwbacks and convention panels frequently highlight his deep pride in Under the Red Hood, stepping into the shoes of the World’s Greatest Detective for The Long Halloween allowed him to explore the psychological interior of Bruce Wayne from the other side of the mentorship equation.
Implications: What Lies Ahead in the New DC Universe?
As James Gunn and Peter Safran restructure the cinematic landscape of DC Studios, the casting of a live-action Batman for The Brave and the Bold remains one of the most heavily guarded secrets in Hollywood.
While Ackles has firmly established his pedigree in the realm of animation, his physical presence, age, and undeniable knack for playing morally complex, weathered vigilantes—honed heavily through his work as Dean Winchester and Soldier Boy—make him an evergreen favorite among comic book purists.
Whether or not Gunn decides to make the leap from casting Ackles in animation to putting him in a live-action Batsuit, Jensen Ackles has already secured a permanent, ironclad legacy in Batman lore. He remains the rare talent who walked out of the shadows of Gotham as an angry, resurrected sidekick, only to return years later as the very protector who failed him.
