Everyone remembers Stitch. He's the blue, fluffy, chaotic-neutral "dog" who learned the meaning of Ohana. But if you grew up watching Lilo & Stitch: The Series on the Disney Channel, you might recall a version of him that was significantly scarier. He was red. He was tall. And honestly, he was a total jerk. Experiment 627, often called "Evile" by the fandom, wasn't just another cousin of the week. He was specifically designed to be the "Anti-Stitch," a creature so powerful and so inherently mean that he makes 626 look like a pampered house cat.
Most of Jumba’s experiments have a quirk or a hidden soft spot. Not this guy.
Why Jumba Created the "Extra Evil" Experiment 627
Success can go to anyone’s head, even a genetic experiment. In the episode titled "627," Stitch gets an ego the size of Kauai after capturing several experiments in a row. He starts acting like a "stuck-up little brat," as the official synopsis puts it. He’s bossy, he’s rude at dinner, and he even covers Jumba in cranberry sauce.
Jumba Jookiba, being the "Evil Genius" that he is, doesn't handle disrespect well. To knock Stitch down a peg, Jumba decides to show him what a real monster looks like. He goes back to the drawing board and creates Experiment 627.

Unlike the other experiments, 627 was made with a very specific, petty purpose: to be better than Stitch in every single way. Jumba didn't just give him one power. He gave him "extra everything." This includes the abilities of about 20 other experiments. It’s a classic case of a creator being so blinded by pride that they build something they can’t actually control.
The Power Set That Broke the Scale
If you look at the stats, 627 is basically a final boss in a world of mid-tier enemies. He has all of Stitch's base physical attributes—super strength, speed, and hypercognition—but dialled up to eleven.
- Physical Dominance: While Stitch has four arms, 627 can sprout six. He also has an extra head, though he usually keeps it tucked away.
- Elemental Arsenal: He can breathe fire, freeze things with frost breath (from Experiment 523, Slushy), and generate green plasma blasts from his eyes, hands, or mouth.
- Energy Manipulation: He’s got electrokinesis from Sparky (221) and telekinesis that’s strong enough to freeze a victim's body movement entirely.
- The "No Flaw" Clause: Jumba specifically programmed him to have none of Stitch's weaknesses. He isn't afraid of water, and more importantly, he is "un-rehabilitatable." He has zero interest in family, surfing, or being good. He only knows one word: "Evil!"
The One Laughable Weakness
So, how do you beat a guy who can lift thousands of tons and fire lasers from his face? You make him laugh.

It’s the ultimate irony of 627's design. Jumba gave him "extra everything," and that included an extra-large sense of humor. Because 627 finds everything hilarious—especially his own cruelty or other people's misfortune—he is prone to fits of uncontrollable, hysterical laughter.
In their final showdown, Lilo and Stitch realize they can’t win through brute force. Stitch is getting absolutely bodied. He’s being bullied and tormented. But then, with a little tip from Reuben (Experiment 625), they realize 627's joy is his downfall. Stitch performs a series of ridiculous, slapstick stunts, and 627 laughs so hard he literally loses consciousness.
It’s a bit of a "deus ex machina" moment, but it fits the tone of the show. You can't out-punch a god-tier alien, but you can definitely out-clown him.
Why 627 Never Got a Name
One of the saddest—or maybe most fitting—details about Experiment 627 is that he’s the only major experiment who never got a "true place" or a human name like "Sparky" or "Angel." Lilo didn't name him. She just dehydrated him back into a pod using a home food dehydrator she bought from a TV commercial.
He was deemed a failure by Jumba, not because he wasn't strong, but because his weakness was so exploitable. He was too "overclocked." After his defeat, he was basically erased from the roster, only making a brief, wordless cameo in Leroy & Stitch.
627 vs. Leroy: Who Is the Real "Anti-Stitch"?
Fans often argue about who the "ultimate" evil experiment is: 627 or Leroy (629).
Leroy was created by Dr. Hämsterviel to be a clone of Stitch that was easier to control. Leroy is definitely more disciplined and had a whole army of clones. But in a one-on-one fight? Most lore experts point toward 627. Leroy is essentially an equal to Stitch, whereas 627 was designed to be his superior. 627 has a much wider range of powers (telekinesis, ice, fire, electricity) that Leroy simply doesn't possess.
The only reason Leroy is more famous is that he got a whole movie. 627 was just a one-episode lesson in humility.
Insights for Fans and Collectors
If you're looking for Experiment 627 in the wild, you're going to have a hard time. Because he was a "failure" and a bit of a niche character from the TV series, he doesn't get much love in the Disney Parks or in merchandise.
- Tokyo and Paris Appearances: He has occasionally appeared as a walk-around character in Disneyland Paris and Tokyo Disneyland, usually during special villain-themed events. He’s hard to miss—he looks like a tall, red, angry Stitch with a meaner face.
- Voice Acting Trivia: In the original series, 627 was voiced by Chris Sanders, the same man who created Stitch and voiced 626. It’s a fun meta-detail: the creator voicing the replacement. In the Stitch! anime, Benjamin Diskin took over the role.
- Live Action Rumors: With the live-action Lilo & Stitch movie arriving in 2025/2026, there have been massive hints about the "Cousin Cinematic Universe." While 627 isn't confirmed for the first film, Jumba's mentions of "turning Stitch into something more" have fans speculating that we might see a CGI version of the red menace in a sequel.
The best way to experience 627 is still the original Season 1, Episode 19 of the animated series. It remains a standout episode because it’s one of the few times Stitch is genuinely outclassed. It reminds us that while Stitch is "626," there was always room for Jumba to make something worse.

If you're revisiting the series, keep an eye out for the "extra arms" scene. The animation for 627's multi-arm combat is surprisingly fluid for 2003 TV standards and really sells the idea that Stitch is in way over his head.
