Invincible and The Boys Had a Secret Crossover — Here’s How a TV Showdown Could Play Out

Short version: Invincible and The Boys basically live in the same neighborhood of 'what if superheroes were actually terrifying,' so of course fans want them to meet. On TV, that ship has sailed for now with The Boys just wrapped. But in the comics? There was a tiny, almost-hidden crossover that technically gave fans exactly what they wanted — and then some.

Two monsters, one idea

Both Invincible and The Boys started as comics outside the DC/Marvel lanes and blew up because they treat capes like crash-test dummies. Prime Video then turned Invincible into one of the wildest animated series going, and The Boys into a live-action Molotov cocktail for the whole superhero industrial complex. They also share a favorite toy: the evil Superman riff. The Boys has Homelander. Invincible has Omni-Man. That overlap is catnip for crossover talk.

The blink-and-you-miss-it crossover that already happened

Here’s the part a lot of people never saw. Back in the day, The Boys #18 had an Emerald City Comic Con textless variant cover. It shows the Boys standing over a bloodied hand. Co-creator Darick Robertson later confirmed that the hand belongs to Invincible. Translation: in that quiet little Easter egg, the Boys killed Invincible. It isn’t an on-page fight scene, it isn’t a full issue, and it isn’t canon to some giant event — it’s a sneaky, almost invisible nod. But it counts as a crossover, however microscopic.

Would that actually happen in a fight?

If we’re talking the Prime Video versions, Mark Grayson would fold the Boys in seconds. Yes, the Boys have experience taking down people way stronger than they are. But in The Boys, the entire endgame is figuring out what to do about Homelander’s raw, untouchable power — and Mark sits on a ledge above that ledge.

• Homelander’s top-shelf moments on the show: tossing heavy machinery (including jets) and leveling buildings. Brutal, sure.
• Invincible’s ceiling: routinely interplanetary flight speeds and durability that makes reentry look like a brisk jog. In the comics, he even helps wipe a whole planet off the map and once fights on the surface of the sun. Different sport.

What about the comics versions of the Boys?

In the source material, the supe-hunters juice up on Compound V, which gives them real-deal super strength. Even then, Homelander still outmuscles them. And comics Invincible is even scarier than his animated counterpart when you stack feats. So if the Boys actually tried to run it at peak Mark? That variant cover’s implication doesn’t survive five seconds of math.

The asterisk

Now, if you drop Invincible into The Boys’ storytelling ecosystem, different rules apply. That world loves to dial heroes down into messier, dumber, or more compromised versions of themselves to make the satire bite. In that context? Yeah, they could probably write a way for the Boys to hand Mark an L he doesn’t deserve. But power-for-power, feat-for-feat, straight-up fight? Invincible wins, and it isn’t close.

So yes, the crossover happened — technically. And no, it doesn’t tell you how a real throwdown would go. On screen or on the page, Mark’s called Invincible for a reason.
