Tech Jacket, a character hinted at throughout the Invincible series, officially appeared in season 4, episode 5. The character’s debut included a surprising twist – a gender swap – which was explained just before Mark and his team prepared to fight in the Viltrumite War.
Okay, so a cool change with the animated Invincible series – the character originally known as Tech Jacket in the comics, Zack Thompson, is now Zoe Thompson. And get this, the voice actor bringing Zoe to life is someone you almost definitely recognize! It’s a familiar voice, and I’m betting a lot of you will pick it out right away.
Now that we’ve discussed the reasons for changing Tech Jacket’s gender, let’s explore who voices the new female version of the character and how her portrayal stacks up against the original male character who wore the Gelderian armor.
Why was Tech Jacket gender-swapped in Invincible season 4?
For season 4 of Invincible, the character Tech Jacket was reimagined as Zoe Thompson, a teenage girl, instead of the original male character, Zack. The show’s creators felt this change would be compelling and add a fresh dynamic to the team of heroes, making the character stand out more.
Robert Kirkman, the creator and co-showrunner of Invincible, explained to Den of Geek that when adapting Tech Jacket for the show, he noticed the character would look a lot like Mark Grayson in the comics.
The creative team quickly decided it would be compelling to reimagine Tech Jacket as a female character named Zoe, exploring what her personality and story would be instead of the original character, Zack.
Kirkman explained that evolving the character allowed for more compelling storylines and highlighted the fresh energy the updated version provides.
This change wasn’t about creating a surprise moment or a quick plot twist. It was a thoughtful choice made to develop the character specifically for the TV show.

Who voices Tech Jacket in Invincible?
Tech Jacket, also known as Zoe Thompson, made her debut in Invincible during season 4, episode 5. The character is voiced by Zoey Deutch, an actress known for her roles in shows like Set It Up, The Politician, Ringer, and The Suite Life on Deck.
This actor is famous for roles in several popular projects, including Harper Moore in the Netflix rom-com Set It Up, Infinity Jackson in the comedy-drama The Politician, and earlier appearances as Juliet Martin on Ringer and Maya Bennett on The Suite Life on Deck.
Simon Racioppa, co-showrunner alongside Kirkman, also praised the decision to change Tech Jacket’s gender. He was particularly impressed with Stephanie Deutch’s performance, noting her humor, professionalism, and deep understanding of the character.

Who is Tech Jacket in the Invincible comics?
If you’re new to Robert Kirkman’s comics, Tech Jacket is a pretty important hero within the Invincible story.
Tech Jacket is actually Zack Thompson, a high school student who finds a powerful, futuristic suit of alien armor. He gets it from a member of a dying alien race called the Geldarians. The suit becomes a permanent part of him, transforming him into an incredibly strong hero.
He’s a new member of the Coalition from Earth – a teenager who fights in a powerful suit of armor. Think of him as a combination of Iron Man’s technology, Green Lantern’s energy powers, and Blue Beetle’s symbiotic armor.
Does the gender swap change Tech Jacket’s story?
Despite the gender swap in Invincible season 4, the core storyline of Tech Jacket will probably remain largely the same, with only minor adjustments to dialogue and a few jokes.
Based on her initial appearances, Zoe seems destined to follow a similar path to Zack in the comic books: she’ll likely join the battle against the Viltrumite Empire and become one of the heroes working alongside Allen and Omni-Man.
Zoe and Oliver have shared a little bit of flirtation, which could develop into a romance later on. However, it seems Zoe will still follow the same main storyline as her male comic book counterpart, but with a fresh perspective and a stronger connection to Mark and the team.
