Supernatural reunion in The Boys Season 5! Jared Padalecki joins as Mister Marathon, teaming with Misha Collins and Jensen Ackles.
- April 14, 2026
AceShowbiz - The Boys fans have long anticipated the involvement of Jared Padalecki in the series’ final season, and now his role has been officially confirmed. After Jensen Ackles was revealed as Soldier Boy, excitement grew among fans of the cult hit series Supernatural hoping for a reunion with their former co-star. Season 5 will deliver exactly that, with Padalecki joining the cast alongside another familiar face from the show, Misha Collins, who portrayed Castiel in the same iconic series.
For some time, the identity of Padalecki’s character was kept a secret. However, during his appearance at the FACTS Convention in Belgium, the actor addressed persistent fan theories head-on. In a video shared on TikTok, Padalecki confirmed he will be portraying Mister Marathon, a character who has been referenced multiple times throughout previous seasons of The Boys. This development fits well with the show's narrative, especially considering the significant death of A-Train in the season 5 premiere, which creates a natural vacancy for Mister Marathon’s arrival.
Mister Marathon is known in the comics as a former member of the Seven whose time on the team was notably brief compared to A-Train. While the comics depict his character as having a short-lived presence and a quick demise, the showrunners appear to be taking a different approach for the television adaptation. Eric Kripke, the creative force behind The Boys, has confirmed that Mister Marathon will appear in episode 5 of the season, sharing the screen with Misha Collins’ character, whose role remains under wraps.
Kripke has intriguingly described both Padalecki and Collins’ characters as "douchebags," which aligns with the limited glimpses the show has offered about Mister Marathon so far. While it remains unclear whether their appearances will be extensive or brief, the casting already provides a satisfying payoff for longtime fans, especially since previous seasons have made several nods to Mister Marathon through characters like A-Train and Lamplighter.
With the confirmation of Padalecki as Mister Marathon, viewers can look forward to how this character will influence the events of the series’ concluding season. Whether as an ally or adversary in the escalating conflict, his presence adds another layer to the intricate world of supes that The Boys has crafted.
