Anime transformations have a weird ability to make us lose our minds. I mean, who wouldn’t like a 180 flip of a character who then serves a banger?
But what makes one truly unforgettable? Is it the new look, the sudden power boost, or the crazy screaming before it happens? To be honest, it can be all three. However, the best ones are more than that. They can turn a fight around, reveal a hidden side of a character, or leave fans talking about one scene for years.
Anime has given us plenty of those moments.
From Dragon Ball and One Piece to Hunter x Hunter, Bleach, Attack on Titan and JoJo’s Bizarre Adventure, these forms have become much more than flashy upgrades.
So let’s rank ten of the best anime transformations by their impact on the story, the characters and the fans watching them.

Adult Gon | Hunter x Hunter
Adult Gon is arguably one of the most disturbing anime transformations. A victory, but at what cost?
Gon spends the Chimera Ant arc desperately trying to find a way to save Kite. When he finally learns what happened to him, something inside Gon completely breaks.
His fight with Neferpitou isn’t a normal shonen power-up moment.
Gon makes a Nen vow, trading away his future potential for the strength he needs right then. He sacrifices everything he could have become as a fighter.
Gon takes on a terrifying adult form, with immense physical strength and that shadow-like aura. He completely overwhelms Pitou. The same kid we’ve watched grow throughout the series becomes almost unrecognisable.
Gon gets stronger at the cost of his own future.
There is something deeply wrong about watching a cheerful kid turn into that version of himself. Togashi doesn’t treat the moment like a victory either.
Gon wins. Somehow, it still feels like the worst thing that could have happened to him.
Blood Chains Ichigo | Bleach
If you’ve been following the current Bleach anime, you already know why this one had to be here.
Blood Chains Ichigo is also the newest transformation on this list.
It made its grand debut in episode 45 of Bleach: Thousand-Year Blood War, and the coolest part? Tite Kubo himself designed and named it specifically for the anime.
When the original creator steps in, you can expect a banger.
The form begins when Ichigo awakens the dormant Hollow blood within him, entering a half-Hollowfied state before releasing Bankai.
Kubo skips the usual Hollow mask this time.
Ichigo keeps his human face, but two white horns appear on his head. Blood-like chains of spiritual pressure wrap around his body. The anime also ties those chains to Ichigo’s increased spiritual pressure, physical performance and reaction speed.
What I love most about this form, though, is what it represents. Ichigo has spent most of Bleach trying to figure out where his different powers belong: Soul Reaper, Hollow, Quincy and human. By this point, those identities aren’t separate boxes anymore. They’re all part of him.
Blood Chains feels like the anime finally embracing everything that makes Ichigo different.
And after all these years, seeing Kubo create a brand-new Ichigo form for the anime is wild.
Ultra Instinct | Dragon Ball Super
When Goku first awakens Ultra Instinct against Jiren, the entire rhythm of the fight changes.
His body starts reacting automatically, without waiting for conscious decisions. Suddenly, Goku’s movements look completely different.
Ultra Instinct Sign already pushes Jiren into taking him seriously. Goku later reaches the completed form during the Tournament of Power.
The visual helps too. Silver eyes, silver hair and that ridiculously calm expression sell the transformation instantly.
Goku suddenly looks like someone who has entered a completely different class of fighter. No wonder Ultra Instinct became one of Dragon Ball Super’s defining images.
Even people who don’t follow Dragon Ball know what Ultra Instinct Goku looks like. If you don’t, you must be living under a rock.
Gear 4 | One Piece
Luffy has always fought like someone who refuses to follow normal rules. Gear 4 took that idea and turned it into something completely insane.
Luffy developed Gear 4 during his two-year training with Rayleigh. He first uses it against Donquixote Doflamingo in Dressrosa. Doflamingo somehow keeps fighting even after Law’s Gamma Knife.
Then Luffy reveals Boundman. Yeah, it looks weird.
His body becomes huge and muscular, his arms and legs are covered in Armament Haki, and he keeps bouncing around instead of standing normally. Doflamingo even laughs when he sees him.
Honestly, I can’t blame him.
The funny part is that the design actually has a purpose. Luffy inflates his muscles with air and combines that with his rubber body and Armament Haki. He can bounce through the air, change the direction of his attacks and throw punches with massive force.
Then comes Kong Gun. Nobody is laughing anymore.
Gear 4 also has a serious drawback. Luffy burns through his Haki quickly. Once the form wears off, he gets exhausted and temporarily loses access to Haki.
Later, he develops Tankman and Snakeman too, each built around a different fighting style.
For me, Gear 4 is memorable because it feels completely like Luffy. The form looks goofy, moves strangely, and still becomes spine-chilling once the fight starts.
That might be the best One Piece thing about it.
Founding Titan | Attack on Titan
Eren’s Founding Titan takes the idea of a transformation to a terrifying extreme.
By the final season, Eren already has the Attack Titan and Founding Titan powers.
Eren reaches Ymir in the Paths, and she finally chooses to lend him the Founding Titan’s full power. That’s when Eren takes on his terrifying final form.
Eren’s final Titan looks almost nothing like the protagonist we met at the beginning. Its enormous skeletal body stretches across the battlefield while the Wall Titans begin moving around the world.
The scale alone is horrifying. Eren has become the centre of a global catastrophe.
Through the Paths, the Founding Titan gives him access to the Subjects of Ymir. The Rumbling then turns that power into a nightmare for the entire world.
The real shock comes from watching Eren choose what to do with it.
Watching the protagonist become the source of the world’s biggest threat remains one of Attack on Titan’s most unsettling turns. Period.
Full Cowl | My Hero Academia
Well, Full Cowl doesn’t look as dramatic as some transformations on this list.
Deku initially treats One For All like a power he can unleash in one massive attack. The problem? His body can’t handle it.
During his training with Gran Torino, Deku learns to spread One For All throughout his entire body. That becomes Full Cowl. Instead of putting everything into one punch, Deku keeps a controlled percentage of One For All flowing through his body. There’s no new hair colour or glowing aura. Deku simply gains control over how he uses One For All.
That gives him better speed, mobility, reflexes and overall control. More importantly, it changes how he fights.
Deku can finally move, dodge, analyse a fight and attack without destroying his own body every few seconds. Full Cowl keeps evolving as Deku does.
For Deku, this is the moment One For All finally starts feeling like something he can actually live with.
Gold Experience Requiem | JoJo's Bizarre Adventure
JoJo has never made its abilities easy to explain. Gold Experience Requiem makes things even harder to explain.
Giorno’s Gold Experience evolves after being pierced by the Stand Arrow.
The result is Gold Experience Requiem.
Its ability can return an opponent’s actions and will to zero. Basically, Diavolo can try to reach the result he wants.
GER can simply say no. That makes the final confrontation completely different from a normal JoJo fight.
Diavolo’s King Crimson can erase time. GER doesn’t need to overpower that ability in the usual sense. It prevents the action from reaching its intended result. Then things get even crazier.
Diavolo becomes trapped in an endless cycle where he repeatedly experiences death without ever reaching a final death. It’s absurd, terrifying and completely at home in JoJo.
What did I just watch?
Demon Lord Rimuru | That Time I Got Reincarnated as a Slime
Rimuru’s Demon Lord evolution hits differently because of what pushes him into it.
He starts out wanting a peaceful life where different races can live together. Then Falmuth attacks Tempest and kills thousands of his people, including Shion.
For Rimuru, that’s the moment everything changes.
He decides to become a True Demon Lord so he can bring the dead back. To complete the evolution, he kills around 20,000 Falmuth soldiers and gathers the souls he needs.
After his Harvest Festival, Rimuru awakens as a True Demon Lord and gains even greater abilities, including Raphael and Beelzebuth. More importantly, Shion and the others return.
Rimuru wanted power to protect the people he calls family.
The peaceful slime who wanted to build a home now has enough power to make entire nations fear him. A pretty wild career change for a blue blob.
Baryon Mode | Boruto
Baryon Mode might be one of the most painful transformations on this list.
Naruto and Kurama activate it during their fight against Isshiki Otsutsuki.
Unlike their usual chakra cooperation, Baryon Mode works through a completely different process.
Naruto and Kurama’s chakra effectively undergoes fusion, creating an enormous burst of energy. The official Naruto site compares the process to nuclear fusion.
Baryon Mode burns through life force. And Naruto isn’t the only one paying for it. Physical contact with Naruto also drains the lifespan of his opponent. That’s what gives him the opening he needs against Isshiki.
The anime makes the stakes even heavier because Kurama ultimately pays the price. He uses his own life to shoulder the burden of Baryon Mode and dies after the battle.
Naruto gains the edge he needs, but every second brings him closer to losing Kurama.
A character who has spent his entire life fighting beside Kurama, that goodbye hurts far more than the transformation itself.
Final Getsuga Tensho | Bleach
Last but not least, we’re back to Bleach. Blood Chains isn’t the first time the series has given Ichigo an unforgettable final form.
Final Getsuga Tensho is one that stays with you long after the fight ends. After training with Zangetsu, Ichigo learns the Final Getsuga Tensho. The technique lets Ichigo use Mugetsu, the attack that ends his fight with Aizen.
But there is one massive problem. Using it costs Ichigo his Soul Reaper powers, which makes the transformation feel genuinely final.
Ichigo isn’t unlocking another permanent level above Bankai. He’s essentially betting everything he has on one attack. His appearance changes completely too. His hair grows longer and darker, while black markings and smoky reiatsu surround his body.
Then comes Mugetsu.
Mugetsu overwhelms Aizen after everything else has failed, leaving him badly wounded before Urahara’s seal finally takes effect.
Ichigo loses his powers afterwards.
For someone who spent the entire series learning how to become stronger, ending with a form that takes that strength away feels strangely fitting.
Takeaway
If you’ve come this far, you can understand how different and dynamic anime transformations can be. That’s its superpower.
Adult Gon has emotional damage. Gear 4 has the sheer Luffy-ness. Baryon Mode has heartbreak. Ultra Instinct has that unforgettable first reveal.
Some of these forms changed a fight. Others changed the character, or even the entire story around them.
Years later, we still talk about these moments because we remember exactly how they made us feel. Isn’t that what makes an anime transformation worth the hype?
