‘Invincible’ Creator Robert Kirkman Explains Why Tech Jacket Was Gender-Swapped in the TV Series

The creator of Invincible, Robert Kirkman, has spoken about a notable change in Season 4 of the Prime Video show. The series introduced a new version of Tech Jacket, changing the character from a male hero in the comics into a female version for the TV adaptation.

Kirkman discussed the decision in an interview with The Wrap, where he explained why the show moved away from the original comic storyline in this case. In the comics, Tech Jacket is Zack Thompson, a powerful character who uses advanced alien technology. In the show, the character is reworked as Zoey Thompson.

He said the original version of Tech Jacket is still a strong and complete character. However, he felt that using Zack in the TV version of the Viltrumite War story did not add anything new compared to other characters already in the show.

Kirkman explained that characters like Mark and Oliver already cover similar ground in the story. Because of that, he felt Zack’s role would overlap too much with them.

As he put it, “There’s just a lot of similarities there.”

Season 4 follows the main heroes as they leave Earth and prepare for a larger battle tied to the Viltrumite War. The team in the original comics includes several major characters such as Mark, Nolan, Oliver, Allen the Alien, Battle Beast, Space Racer, and Zack Thompson.

In the TV version, the lineup is slightly changed. Tech Jacket is still part of the group, but now appears as Zoey instead of Zack. According to Kirkman, this change also helps balance the cast and avoid having too many similar male characters in one team.

He also reflected on the early days of the comic book Invincible. Kirkman said that when he and Cory Walker started the series, they were very young and did not think much about character diversity at the time.

He explained it by saying, “One of the downsides of Invincible is Cory Walker and I were like 23 and 21 when we started that book, and your default when you’re not really paying attention is yourself. Every time we introduce another character, ‘Oh look! It’s another white male! Who knew?’ It’s just a shortcoming that we hadn’t quite noticed and done our due diligence to correct.”

The fourth season of Invincible recently ended with its final episode airing on April 22 on Prime Video. Fans are now waiting for updates about Season 5 and how the story will continue.

Changes like this are very common when comics are adapted into TV shows. Sometimes it helps the story feel more balanced and fresh, even if it changes things from the original source. At the same time, fans of the comics can feel divided when characters are altered. What do you think about this change in Invincible? Do you prefer adaptations that stay close to the source material, or are changes like this fine if they improve the story?
