What happens to a superhero universe when its central hero is no longer the only one carrying the name? Invincible, the Amazon Prime Video animated series based on Robert Kirkman’s comic book run, appears to be quietly laying the groundwork for exactly that kind of shift — and the character at the center of it is Bulletproof.
Fans of the show have been paying close attention to how Bulletproof has been positioned in recent episodes, and the signs are pointing toward something significant. The series has a long history of seeding future storylines well in advance, and the treatment of Bulletproof seems to follow that same deliberate pattern.
It’s worth being upfront: What follows draws on verifiable general knowledge about the Invincible comic book source material and what is publicly known about the animated series’ trajectory, rather than specific episode details that cannot be independently confirmed.
Who Is Bulletproof, and Why Does He Matter to the Future of Invincible?
Bulletproof — real name Zandale Randolph — is a superhero who exists in the same world as Mark Grayson, the young man who takes on the Invincible mantle after discovering his Viltrumite heritage. In the original comic books by Robert Kirkman, Bulletproof eventually takes over the Invincible name and costume during a period when Mark is unable to fulfill that role.
That storyline is one of the more memorable arcs in the comics precisely because it challenges the assumption that a superhero identity belongs permanently to one person. Bulletproof wearing the Invincible suit isn’t framed as a betrayal or a gimmick — it’s treated as a genuine passing of responsibility, even if temporarily.
The animated series has consistently followed the comics’ major plot beats while making adjustments for pacing and medium. If the show is beginning to build Bulletproof’s presence with more intention, it strongly suggests the creative team has that arc in mind.
How the Show Has Been Setting This Up
One of the defining qualities of Invincible as a series — both in print and on screen — is its willingness to plant seeds seasons before they pay off. Characters who appear briefly in early episodes return with major consequences later. Relationships established in passing become critical turning points.
Bulletproof fits that pattern. His appearances in the animated series have given him enough presence to register with audiences without fully explaining his long-term importance. That kind of careful, measured introduction is typically how the show handles characters it intends to use in a bigger way down the line.
There’s also the matter of what the comics establish about Bulletproof’s power set. He shares certain invulnerability traits that make the idea of him wearing the Invincible name feel earned rather than arbitrary. The show would need its audience to already believe in Bulletproof as a legitimate hero before that transition could land emotionally.
What the Comics Tell Us About Where This Could Go
For viewers who haven’t read Kirkman’s source material, the comics offer a useful roadmap — with the caveat that the show doesn’t follow every detail exactly.
- In the comics, Mark Grayson faces circumstances that make it impossible for him to operate as Invincible for a period of time.
- Bulletproof steps in to maintain the Invincible identity during that absence, wearing the costume and operating under the name.
- The arrangement is temporary, but it carries real weight — both for Bulletproof as a character and for what it means to hold that identity.
- Mark eventually returns to the role, but the experience changes how both characters are perceived within the story’s world.
The animated series has already demonstrated it’s willing to go to dark, complicated places. A storyline built around legacy, identity, and what it means to be a hero when the original hero is gone fits perfectly within the show’s thematic DNA.

Why This Storyline Would Hit Differently on Screen
Legacy hero arcs have become a staple of superhero storytelling across film, television, and comics — but they don’t always land. The ones that work do so because the audience has been given enough time to care about both the original hero and the person stepping into their shoes.
Invincible has spent multiple seasons making Mark Grayson feel real and earned. If the show follows through on the Bulletproof arc, that investment pays off in a specific way: audiences would feel the weight of Mark’s absence precisely because they’ve been with him through everything that came before.
That’s the kind of emotional storytelling the series has always been built on. It’s not about shock value — it’s about consequence. Every major event in Invincible carries a cost, and a storyline where someone else has to carry the name Mark built would be no different.
Whether the show executes this arc in season four or further down the line remains to be seen. But the pieces are clearly being moved into position.
