Invincible Creator Reveals the Real Reason a Major Character Was Gender-Swapped in Season 4

So, Invincible just dropped its season 4 finale on Prime Video, and if you haven’t been keeping up, yes, things got wild. And right on cue, Invincible creator Robert Kirkman is making headlines—not for another hideously gory plot twist, but because he decided to give one of the comic’s superpowered side characters a bit of a reboot, and fans are talking.

Tech Jacket—Now with 100% More Zoey Deutch

If you haven’t memorized the Invincible cast of comic-book deep cuts (I don't blame you), Tech Jacket is a character who, in Kirkman’s original comics, is a pretty standard high school teen named Zack Thompson. Here’s the thing: Tech Jacket actually showed up a full year before Mark Grayson and the whole Invincible saga even started, so he’s not just some bit player wedged in for canon cred.

But the show took a left turn and introduced Tech Jacket as Zoe Thompson instead—same basic premise (teenager, alien suit, superhero shenanigans), but this time played by Zoey Deutch. Kirkman told TheWrap why he flipped the script:

Basically: They didn't need another teen guy with a high-tech suit on the team, especially with Mark and Oliver already filling that narrative space. So Zoe gets a turn.

An Honest Look in the Mirror

Kirkman got pretty candid about it. Back when he and artist Cory Walker kicked off Invincible in their early 20s, their default was, well, writing guys who looked and acted like them. 'Oh look! It’s another white male! Who knew?' is how Kirkman put it—not exactly subtle, but refreshingly honest by comics standards. It’s a creative oversight they’re now actively course-correcting, and honestly, it shows.

Zoe’s Character—Still a Lot We Don’t Know

We don’t have the full backstory for Zoe Thompson yet, but Kirkman pointed out that his own daughter influenced the character (especially the parts where Zoe's dad tries—and fails—to keep her from cursing). That dynamic shows up on screen, with Saturday Night Live’s Bobby Moynihan voicing Zoe’s dad, and for those keeping tabs on all the cameos, LeVar Burton is the voice of Zoe’s suit AI—because apparently every other voice actor alive wants in on this show.

Kirkman also told Den of Geek that Zoey Deutch brings something extra to the character’s energy, calling her 'a really, really cool character that we’re having a ton of fun with.' So, expect to see a lot more of her as Invincible barrels towards what Kirkman says could be four more seasons.

This Isn’t the First Gender Swap

Quick rundown for people keeping score—this isn’t the show’s first time updating character genders:

• In episode one, Green Ghost (played by Sonequa Martin-Green) appears briefly as a woman with intangibility powers before getting wiped out alongside the rest of the Guardians of the Globe. In the original comics? Green Ghost was a guy.
• Shrinking Rae, voiced by Grey DeLisle, is another switch. She’s the show’s tiny hero who, unlike her quick-to-die predecessor above, actually survives past episode one. Again, male in the comics (as Shrinking Ray), female here.
• Now Tech Jacket, aka Zoe Thompson, joins the list.

Might sound like a small thing, but after decades of beige male superheroes, these changes actually make the team feel a bit less like a 20-year-old’s dorm room.

What’s Next?

No timeline whiplash here: Prime Video is working on Invincible season 5, which, if everything stays on track, should show up in early 2027. There’s a lot of ground left to cover in the story, and, with Kirkman at the helm, probably a few more surprises in store—both for the characters, and for fans hunting for comic-to-screen differences.
