Red fur. Eye shadow. A tail. Honestly, back in 1997, nobody saw it coming. When Dragon Ball GT Goku Super Saiyan 4 first hit TV screens in Japan, it felt like a total departure from everything Akira Toriyama had established in the Frieza and Cell sagas. We were used to hair getting longer or turning gold. Suddenly, we had a transformation that looked like a literal throwback to the Oozaru roots of the Saiyan race.
It’s wild.
Even now, years after Dragon Ball Super introduced gods and angels, fans still argue about whether the SSJ4 design is actually superior to the "palette swaps" of Blue and Red. There’s a certain weight to it. It doesn't just feel like a power-up; it feels like a character evolution that ties the entire lore of the Saiyans together, from the Great Ape to the humanoid warrior.
The Science of the Blutz Wave and the Golden Ape
To understand how we got to Dragon Ball GT Goku Super Saiyan 4, you have to look at the weird pseudo-science the writers at Toei Animation cooked up. It wasn't about screaming until your hair turned a different color. It was about biological triggers. Specifically, Blutz Waves.
Usually, a Saiyan needs a moon to go Great Ape. But to reach this specific peak in GT, Goku had to achieve the Golden Great Ape form first. It's basically what happens when a Super Saiyan goes Oozaru. It’s chaotic. It’s mindless. Goku was literally rampaging, destroying everything in sight until Pan managed to reach his human heart. That’s the "conscious" trigger.
The transformation itself is a compression of that massive, planetary-level ape power into a concentrated human frame. Think about that for a second. Instead of a giant, slow monster, you have all that raw, primal energy packed into a six-foot-tall martial artist. Katsuyoshi Nakatsuru, the character designer, really leaned into the "wild" aspect here. He gave Goku that distinct red fur and the heavily lined eyes that make him look less like a superhero and more like a mythological deity.
What Actually Makes Dragon Ball GT Goku Super Saiyan 4 Different?
Most people assume it’s just another multiplier. It’s not. In the context of GT, this form was the only way Goku could even touch Baby Vegeta.

One thing that gets missed is the voice. Masako Nozawa (and Sean Schemmel in the dub) changed the delivery. Goku sounds older. He sounds serious. In his base form in GT, he was stuck in a child’s body, which—let’s be honest—was a controversial creative choice that polarized the fanbase for decades. But the Dragon Ball GT Goku Super Saiyan 4 transformation temporarily bypassed the Black Star Dragon Balls' wish. It forced his body back into an adult state.
It brought back the stakes.
There's a specific nuance to his abilities here, too. He isn't just faster. He’s more durable. He took a 10x Kamehameha from Baby and barely blinked. Plus, he developed the 10x Red Kamehameha, which remains one of the most visually iconic attacks in the franchise. It’s visceral.
Why the Design Outlasted the Show
Dragon Ball GT is often the "black sheep" of the franchise. Fans love to hate on the Para Para Brothers or the slow pacing of the early space-travel episodes. But almost everyone agrees that the SSJ4 design is a 10/10.
Why? Because it’s original.
Super Saiyan 1, 2, and 3 are all incremental changes. Super Saiyan Blue is a color swap. But Dragon Ball GT Goku Super Saiyan 4 changed the anatomy. It brought back the tail—a crucial part of Saiyan heritage that Toriyama eventually phased out because he found it annoying to draw. By bringing the tail back and making it the source of the power, GT felt like it was respecting the history of Dragon Ball more than the modern sequels sometimes do.

Addressing the Canon Debate
Look, we know. GT isn't "canon" in the sense that it doesn't follow the timeline established by Dragon Ball Super. It exists in its own bubble—a "Grand Touring" side story. But in 2026, with the multiverse concept being so prevalent in gaming and media, the line between canon and non-canon is blurring.
Dragon Ball Heroes and various video games like Xenoverse 2 and Dokkan Battle keep this form alive because it sells. It's a money maker. People want to play as Dragon Ball GT Goku Super Saiyan 4 because he feels more like a "warrior" than the leaner, slimmer designs of the God forms. There’s a ruggedness to the fur and the long, unkempt black hair that resonates with the original "barbarian" lore of the Saiyan race.
Some fans argue that SSJ4 should be brought into the main Super timeline, maybe through Broly. It makes sense, right? Broly already uses a "Wrathful" form that taps into Great Ape power without transforming. He's halfway there.
Power Scaling: SSJ4 vs. Blue
This is the rabbit hole every fan falls down eventually. Who wins?
If we look at the official guides from the 90s, SSJ4 was described as the "ultimate" form. But Super has moved the goalposts. Super Saiyan Blue utilizes "God Ki," which supposedly can't be sensed by mortals. However, in the Dragon Ball Heroes promotional anime, we actually see Xeno Goku (SSJ4) fight CC Goku (Blue).
The result? They were basically even.

It suggests that while the paths to power are different—one being "Divine" and the other being "Primal"—the peak output is remarkably similar. SSJ4 relies on the absolute mastery of the biological Saiyan heritage. Blue relies on calmness and external ki control. It’s a classic "nature vs. nurture" argument played out through screaming anime men.
The Misconception of the "Magic" Clothes
One of the funniest things about the Dragon Ball GT Goku Super Saiyan 4 transformation is the clothes. When Goku turns into a kid, his clothes shrink. When he goes SSJ4, he grows, and suddenly he’s wearing new pants and wristbands. When he powers down, the kid clothes are back.
Toei never really gave a great explanation for this. Fans usually just chalk it up to "Magic Clothing" or the idea that the transformation is so mystical it manifests a physical outfit. It’s a bit silly, but in a world with talking pigs and wish-granting dragons, it's a small pill to swallow.
Why You Should Care About SSJ4 Today
If you're a fan of the series, SSJ4 represents a bridge. It bridges the gap between the Z-warriors we grew up with and the ancient history of Planet Vegeta. It’s a reminder that Goku isn't just a hero; he's an alien with a monstrous lineage.
When you watch the fight against Omega Shenron, you see the desperation. You see how the form pushes Goku to his absolute limit. It wasn't just about a new hair color; it was about the survival of the Earth against the consequences of using the Dragon Balls too much. That’s a heavy theme.
Actionable Insights for Fans and Collectors
If you're looking to dive deeper into this specific era of Goku, here is how you should approach it:
- Watch the "Baby Saga" specifically. If you find the early episodes of GT too slow, skip to episode 22. That’s where the momentum builds toward the first SSJ4 appearance in episode 34.
- Check out the Figure-rise Standard Model Kits. Unlike the standard action figures, these kits allow you to see the muscle anatomy and how the fur was designed to flow. It’s a great way to appreciate the character design.
- Play Dragon Ball FighterZ. The SSJ4 version of Gogeta in that game is perhaps the best modern representation of how this power should feel—heavy, fast, and devastatingly stylish.
- Read the GT Perfect Files. These are older Japanese guidebooks (available in translation online) that explain the Blutz Wave theory and the specific "Primal" nature of the form in much more detail than the show ever did.
Dragon Ball GT Goku Super Saiyan 4 remains a pinnacle of character design. It proves that even when a show has its flaws, a single, powerful idea can define a legacy for over thirty years. Whether it's "canon" or not doesn't really matter when the form is this cool. It’s the ultimate tribute to the Great Ape that started it all.
