Let’s be real for a second. When we first saw Goku’s hair turn neon cyan in Resurrection ‘F’, the reaction was... mixed. Some people loved the sleek, godly aesthetic, while others felt like Akira Toriyama was just reaching for the nearest highlighter. Honestly, the jump to Dragon Ball Z Goku Super Saiyan Blue—or Super Saiyan God Super Saiyan, if you want to be a stickler for the original mouth-numbing name—marked a massive shift in how power levels worked in the franchise. It wasn't just about screaming louder or growing more hair. It was about control.
Most fans grew up watching the golden-haired transformations where the ground literally shattered under Goku’s feet. But Blue? Blue is weird. It’s quiet. It’s "godly." And if you’ve been following the series since the 90s, you know that this specific form changed the stakes forever.
The Science of Divine Ki
Super Saiyan Blue isn't just a recolor. To understand why Dragon Ball Z Goku Super Saiyan Blue actually matters, you have to look at the mechanics of Ki. In the Battle of Gods arc, we learned about Divine Ki, a type of energy that normal humans and even high-level fighters like Piccolo can’t even sense.
Basically, the form is what happens when a Saiyan who has already achieved the red-haired Super Saiyan God state goes Super Saiyan on top of it. It’s a layer cake of power. Think of Super Saiyan God (the red form) as the base foundation of divine energy. When Goku pushes that energy through the traditional Super Saiyan transformation, the result is the blue flame. It represents total Ki control. Unlike Super Saiyan 3, which leaks energy like a broken faucet, Blue is about keeping everything inside. This is why Goku can use it for extended periods, though it does have a massive initial "drain" cost when he first clicks it on.
Why the Design Caused a Riot
Some fans felt cheated. You’ve probably seen the memes. "What’s next? Rainbow Goku? Pink Goku?" (Well, we did get Rose, so they weren't far off). But Toriyama’s design philosophy for Dragon Ball Super was a deliberate pivot away from the "more is better" approach of the 90s.

By making the hair blue, the goal was to represent a sense of calm and clarity. The color blue is often associated with tranquility in Japanese culture. It fits Goku’s evolution from a brash brawler to a martial arts master who is literally stepping into the realm of the gods. If you look at the aura, it’s not jagged like the golden forms; it’s fluid, like water or a flickering gas flame. It looks more sophisticated. Sorta.
The Power Scaling Problem
Here is where things get messy. One of the biggest complaints about Dragon Ball Z Goku Super Saiyan Blue is how it ruined the "power ceiling." In the old days, a transformation meant the fight was over. If Goku went Super Saiyan against Frieza, Frieza was toast.
But in Dragon Ball Super, we see Goku in his Blue form struggling against characters like Krillin during sparring matches or getting pushed back by Android 17. It feels inconsistent. The explanation given by the writers (and backed up in the manga) is that Goku is so good at Ki control in this form that he can dial his power down to 1% just to test his friends without vaporizing them. It’s a convenient excuse, sure, but it changed the tension of the show. We went from "Goku is unstoppable" to "Goku is testing his limits," which is a very different vibe for a shonen anime.
Manga vs. Anime: A Tale of Two Blues
If you only watched the anime, you’re missing half the story. The manga, illustrated by Toyotarou, treats the Blue form with a lot more respect regarding its stamina flaws.

In the Goku Black arc of the manga, Goku and Vegeta can't just spam the form. They actually use a "switching" technique where they stay in the red God form to move and only flicker into Blue for a millisecond when they land a punch. This preserves their energy. Later, Goku develops "Perfected Super Saiyan Blue," where he learns to seal all that overflowing aura inside his body. It’s incredibly painful and physically taxing, but it puts him on a level where he can actually go toe-to-toe with Fused Zamasu. The anime didn't really focus on these technicalities; it just leaned into the "Blue + Kaioken" combo, which looked cool but made the power scaling even more confusing.
The Iconic Moments That Saved the Form
Despite the gripes, you can't deny that Dragon Ball Z Goku Super Saiyan Blue gave us some of the best animation in the series' history.
- The Kaioken x10 moment: During the tournament against Universe 6, when Goku layered the red Kaioken aura over the blue? That was peak. It was a throwback to the Saiyan Saga but on a cosmic scale.
- The Broly Movie: Seeing the transformation sequence in the Dragon Ball Super: Broly movie was a game-changer. The way Goku’s hair flashed through green and yellow before settling into that icy blue showed the visceral struggle of the transformation.
- The Final Flash / Kamehameha combos: Seeing Blue Goku and Blue Vegeta fight side-by-side against Jiren or Broly is what the fans were ultimately there for.
Addressing the "Super Saiyan Blue is Weak" Myth
There’s a common narrative that Blue is a "jobber" form—meaning it only exists to get beaten up so the next form (Ultra Instinct) looks better. That’s a bit of an exaggeration.
You have to remember the level of opponents Goku is facing now. He isn't fighting warlords anymore; he’s fighting literal Gods of Destruction and multiverse-tier threats. Blue is the "workhorse" form. It’s the reliable state Goku uses when he needs to be serious but hasn't yet reached that zen-like state of Ultra Instinct. Without the mastery of Blue, Goku never would have survived the Tournament of Power long enough to trigger his silver-haired form.

Moving Beyond the Blue
While Dragon Ball Z Goku Super Saiyan Blue was the face of the franchise for nearly a decade, we’ve moved into the "Ultra" era. With Goku mastering Ultra Instinct and Vegeta moving into Ultra Ego, the Blue form has become the new "Super Saiyan 1." It’s the baseline for high-level combat.
Does that make it obsolete? Not really. It represents the era where Dragon Ball went global again. It’s the form that graced the covers of FighterZ and brought a whole new generation into the fold. Whether you love the blue hair or miss the gold, it’s an undeniable part of Goku’s journey from a kid in the woods to a man who can challenge the heavens.
Actionable Steps for Fans and Collectors
If you're looking to dive deeper into this specific era of Goku's evolution, stop just watching clips on YouTube and check out these specific resources:
- Read the Manga (Volumes 4-5): The "Future Trunks" arc in the manga explains the stamina drain of Super Saiyan Blue much better than the anime does. It makes the form feel more strategic and less like a "power-up button."
- Master the Form in FighterZ: If you play Dragon Ball FighterZ, Blue Goku is a technical beast. Unlike the standard Super Saiyan Goku, the Blue version relies on "loops" and high-pressure teleports. It’s a great way to "feel" the speed and precision the form is supposed to represent.
- Check the "Resurrection 'F'" Storyboard Notes: If you can find the behind-the-scenes interviews with Toriyama from 2015, he explains that he chose blue because "by overcoming a certain limit, he has become both strong and tranquil, able to keep his composure in a fight."
- Watch the Broly Movie in 4K: If you want to see the definitive visual representation of the form, the Dragon Ball Super: Broly film is the gold standard (or blue standard). The "transformation" scene where Goku's hair turns blue is widely considered one of the best pieces of animation in the entire franchise's history.
The Blue era might be transitioning into something else, but its impact on the lore is permanent. It bridged the gap between mortal strength and divine power, setting the stage for everything we're seeing in the current Dragon Ball Super chapters.
