Jared Padalecki’s The Boys Role Reveal Is a Game-Changer

Jared Padalecki is finally suiting up for The Boys, and now we know who he is playing. Short version: it is a deep-cut pick with messy history, perfect for a late-season swing and a little reunion chaos.So who is Jared playing?Padalecki confirmed at the FACTS Convention in Belgium — in a clip that made its way to TikTok — that he is Mister Marathon in Season 5. If that name rings a bell, it should. Mister Marathon has been name-dropped in the show and shows up in flashbacks in the comics. He is a former member of The Seven whose tenure was brief. His whole thing is speed — as in 'fastest man' speed — and in the lore he is the guy A-Train replaces.Why this matters right nowSeason 5 opened by killing A-Train. If Vought suddenly needs a speedster again (they do), the door swings wide open for Mister Marathon. The Season 5 trailer fuels that idea too: it sure looks like Soldier Boy and Homelander are hunting him down for... something. A recruitment? A mission? Either way, they want what he can do.How the comics handled him (and how the show might not)In the comics, Mister Marathon dies on a mission with Homelander, and that death clears the lane for A-Train to join The Seven. If he is alive in the show timeline — which, based on Season 5, he is — expect the series to remix the details. The Boys rarely lifts the page straight off the book. Eric Kripke told Entertainment Weekly that Padalecki and Misha Collins are playing 'douchebags' — 'not morally upstanding dudes.' Why Padalecki fits this perfectlyPadalecki is usually cast as the decent guy trying to do the right thing — Sam Winchester, Walker, early-days Gilmore Girls. But when Supernatural let him go dark (Lucifer possession, soulless Sam), he was great at blending menace with a dry wink. Mister Marathon gives him room to lean into that side, especially bouncing off Jensen Ackles back as Soldier Boy and whatever Misha Collins is up to.The reunion angle (and the timeline)This has been brewing for a while. Back in 2025, an Instagram post revealed both Padalecki and Collins would guest star in the final season. Not exactly a shock given creator Eric Kripke keeps raiding his Supernatural past — Jensen Ackles, Jeffrey Dean Morgan, and Jim Beaver already crossed over — but it is still a crowd-pleaser. Season 5 is the final chapter, Ackles is back as Soldier Boy, and the trailer openly teases the on-screen reunion. Padalecki has not appeared yet, but he is scheduled to show up in Season 5, Episode 5. Not a long wait.What this could mean for Season 5If Homelander and Soldier Boy are chasing Mister Marathon, they either want him back in The Seven or they need his speed for a job that only ends one of two ways in this show: useful asset or dead liability. Given the franchise track record, neither option is exactly safe.The Kripke-verse roll call on The BoysJensen Ackles: Soldier Boy, back for the final season Jared Padalecki: Mister Marathon, debuting in Season 5, Episode 5 Misha Collins: guesting in the final season; character still under wraps Jeffrey Dean Morgan and Jim Beaver: already appeared in earlier seasons Bottom line: Mister Marathon is a savvy pick — a legacy name with baggage, a clean way to fill the A-Train void, and a role that lets Padalecki play dirty. I am in.
