If you grew up watching Disney XD during that weird, experimental mid-2010s era, you definitely remember the absolute chaos of Penn Zero: Part-Time Hero. It was a show about a kid jumping into different dimensions to fill in for heroes who were basically on strike or missing. While Penn was the leader and Boone was the "wise man" (who usually just ate cereal or did something goofy), there was one person actually keeping everyone alive.
Honestly, we need to talk about Penn Zero Part Time Hero Sashi.

Sashi Kobayashi wasn't just a sidekick. She was the muscle, the brains, and the only reason the team didn't get eaten by a dinosaur or disintegrated in a glitchy video game world five minutes into every episode. She’s the character that most people remember because, let’s be real, she was way cooler than the actual hero.
Who Exactly is Sashi Kobayashi?
Sashi is the "part-time sidekick" of the group. While Penn is the "part-time hero" and Boone is the "part-time wise man," Sashi is the one who handles the heavy lifting. Literally.
She’s got this intense, no-nonsense personality that usually borders on being a bit aggressive. She’s small, but she packs a punch—and she’s usually the first one to charge into a fight while Penn is still trying to figure out the moral of the story.
What’s kinda funny is her home life. Her parents, Sylvester and Tia Kobayashi (voiced by the legend George Takei and Lauren Tom), are the sweetest, most unassuming people ever. For the longest time, they actually thought Sashi worked at a "Fish Stick on a Stick" restaurant. Imagine thinking your daughter is breading fish when she’s actually fighting interdimensional villains across the multiverse.
The Specs: Her Iconic Gadget
You can't talk about Penn Zero Part Time Hero Sashi without mentioning those futuristic glasses she wears. They’re called "The Specs."
These aren't just for show. They act as the team’s mission control. Sashi uses them to:
- Project holographic mission briefs.
- Scan environments for threats.
- Keep the boys from getting lost (which happened a lot).
The Dynamic That Actually Made the Show Work
Most cartoons have a "tough girl" character, but Sashi felt different. She wasn't just "the girl" on the team; she was the team's anchor.
There’s this one episode, "The Princess Most Fair," where the team zaps into a musical medieval world. Penn ends up as the princess, and Sashi is the knight. It flipped the script, but it felt so natural because Sashi always had that "protector" energy.
You’ve probably noticed that the show gets surprisingly deep with her character. Underneath all that yelling and combat training, she’s actually incredibly loyal. She’s the "glue" that keeps the trio together. Penn even admits at one point that without her, they’d be completely lost.
Why Sashi Was More Competent Than Penn
It’s a running gag in the show, but it’s also just true. Rippen, the main villain (voiced by Alfred Molina), often refers to Sashi as "the competent one."
Penn is great, don't get me wrong. He’s brave and he cares. But he’s also a teenager who gets distracted by his own ego or his parents being trapped in the "Most Dangerous World Imaginable." Sashi is the one who stays focused on the objective.
The Voice Behind the Fury
A huge reason Sashi worked so well was the voice acting. Tania Gunadi brought this perfect mix of raspy toughness and genuine vulnerability to the role.
Gunadi has done a ton of voice work (you might know her from Transformers: Prime or The Lion Guard), but Sashi is easily one of her most high-energy characters. She had to do a lot of screaming for those battle scenes, and it really sold the idea that Sashi was a force of nature.
What Most People Get Wrong About Sashi
A lot of casual fans think Sashi is just "angry."
That’s a bit of a surface-level take. If you watch the later episodes, especially in Season 2, you see a lot more of her softer side. Her relationship with Penn develops into something more than just partners—it’s heavily implied (and basically confirmed) that they have feelings for each other.
She isn't just a "muscle" character. She’s someone who feels a lot of pressure to be perfect because she knows the stakes. If she fails, her friends don't just lose a game; they might not come home.
The Legacy of Penn Zero Part Time Hero Sashi
Penn Zero only ran for two seasons, which is a crime if you ask me. But in that short time, Sashi became a bit of a cult favorite in the animation community.
She broke the mold of the "sidekick" by being the most capable member of the trio. She proved that you don't need to be the "chosen one" to be the person who actually saves the day.
Actionable Takeaways for Fans
If you're looking to revisit the series or dive deeper into Sashi's character, here’s what you should do:
- Watch "Chuckle City" (Season 1, Episode 5): It’s a great episode where Sashi has to tap into her "silly side," which is basically her worst nightmare. It shows her range.
- Look for the small details in the background: The show creators (Sam Levine and Jared Bush) hidden a lot of lore about Sashi’s family and her training.
- Check out the "At the Odyssey" shorts: These provide a bit more context on what the characters do between missions.
Sashi Kobayashi remains one of the most underrated characters in Disney XD history. She was tough, smart, and fiercely protective of her "idiot" friends.
Whether she was a knight, a space captain, or a giant monster, she was always the heart of the team. If you haven't watched the show in a while, it’s worth a rewatch just to see her carry the entire team on her back.
To get the most out of your rewatch, focus on the episodes where Sashi is forced into roles that contradict her "tough" persona, as these offer the most significant character growth. You can find the full series on Disney+ or various digital retailers.
