If you thought the biggest surprise of Invincible Season 3 was how much damage Mark Grayson could take before his bones just gave up, think again. The post-credits scene of the finale has fans spiraling into wild theories, rewatching episodes for clues, and, let’s be honest, probably screaming into their pillows.
Why? Because Damien Darkblood is back, and he’s in Hell. Not only that, but he’s having a casual chat with Satan himself about possibly dragging Mark down with him.
This was not in the comics. This was never in the comics. And the best part? It turns Invincible into something more than just a faithful adaptation, it’s now a playground where even longtime fans have no idea what’s coming next. So, let’s dive into this demon-sized curveball and see what the mastermind himself, Robert Kirkman, had to say about it.
Robert Kirkman’s hellish story arc that almost never was
You know how every major superhero eventually gets a one-way ticket to Hell? It’s basically a rite of passage at this point. Superman? Been there. Batman? Has a time-share. Spider-Man? Webbed up a demon once. But Invincible? He never got his turn in the comics.
Robert Kirkman, the mastermind behind Invincible, recently admitted to Variety that he always wanted to throw Mark into the fiery depths of Hell for a showdown with Satan, but the timing was never quite right. Across 144 issues, there was always something more pressing, like, you know, an alien invasion, genocidal Viltrumites, or Mark’s dad punching him into another continent. Classic superhero scheduling conflicts.
But thanks to the magic of animation and Kirkman’s willingness to finally cross this off his storytelling bucket list, we’re about to get the Hell arc that never was. And the key to making it work? Damien Darkblood.
Damien Darkblood, the detective who refused to stay gone
If you’re thinking, “Wait, I haven’t seen Damien since Season 1,” you’re absolutely right. The trench-coat-wearing, Rorschach-sounding, demon detective was sent to Hell by Cecil way back when, something that never actually happened in the comics. At the time, it seemed like a convenient way to write him out of the show. But, surprise! He’s back, and he’s got unfinished business.
And let’s not forget the absolute legend that is Clancy Brown. The man’s voice alone makes you want to confess to crimes you didn’t even commit. So when he sits down in the Invincible post-credits scene and starts chatting with Bruce Campbell’s Satan about a Mark Grayson possession scheme, it’s impossible not to feel chills.
So what does this mean for Season 4? Well, first off, it means Invincible is about to get even weirder, which is saying a lot for a show where a guy once punched through a kaiju like it was wet cardboard. Will Mark have to fight off literal demons? Will he get possessed? Will he need an exorcism? All we know is that Kirkman isn’t afraid to take the animated series in bold, unpredictable directions.
And with Season 4 confirmed for 2026, we’ve got a lot of time to speculate wildly, and rewatch every episode while we’re at it. Whatever happens next, one thing’s for sure, Invincible is no longer just an adaptation, it’s an evolution.
Invincible can be streamed on Amazon Prime Video.
