Top 10 Anime "What Ifs" That Totally Change the Story - Fabl...

Anime fans love to ask the big questions - not just “who would win in a fight,” but the deeper ones. The ones that could completely rewrite history. From the moment a single character lives instead of dies, or loses instead of wins, the butterfly effect spreads through timelines faster than you can say “multiverse arc.”

So let’s dive into 10 anime “what if” scenarios that would absolutely flip your favorite stories upside down - but in the most fascinating ways possible.

1. What If Muzan Consumed Nezuko? (Demon Slayer: Kimetsu no Yaiba)

Imagine the Infinity Castle battle ending in Muzan’s victory - and instead of burning under the sun, he takes the ultimate risk and devours Nezuko.

On paper, he wins: Muzan becomes immune to sunlight. But here’s the twist - Nezuko’s humanity infects him like a virus. Her innate instinct to protect humans becomes a curse within him. Suddenly, every time Muzan tries to consume a human, he’s paralyzed by guilt, fear, and even compassion.

The result? A sun-immune Demon King tormented by empathy - the ultimate punishment for his sins.

2. What If Minato Never Died? (Naruto)

If Minato survived the Nine-Tails attack, the entire Leaf Village timeline would shift.

For starters, Naruto wouldn’t be a Jinchūriki. The village wouldn’t ostracize him, meaning he might’ve grown up as a prodigy instead of an underdog. Kushina survives too, guiding him in chakra control from day one. The Third Hokage would remain retired, and the political balance of Konoha would stay intact - no Danzo scheming in the shadows.

But the biggest change? Naruto’s drive to earn respect would vanish. Without pain and isolation, the boy who became the world’s greatest hero might have just been... another golden child.

3. What If Goten Dies Before Fusion? (Dragon Ball Z)

Without Goten, Trunks loses his fusion partner - no Gotenks, no Super Saiyan 3 antics. The Majin Buu fight gets very real.

In desperation, Gohan might be forced to re-enter the battlefield, pushing his Mystic form to its absolute limit. Piccolo might even fuse with Dende or another Namekian to compensate for the power gap.

And since there’s no fusion dance, Vegito never happens - meaning the Z Fighters would have to depend on strategy over raw power. It’s a darker, more desperate arc - one that could actually end with Earth’s destruction.

4. What If L Died Early? (Death Note)

If Light outsmarted L early, his god complex would have no leash. Without L’s intellectual equal to check him, Light would go full tyrant.

He’d likely start controlling political systems, manipulating leaders, and turning the Kira world into an actual dictatorship. Near and Mello wouldn’t even get their shot - because by then, Light would have already rewritten the world in his image.

In short: humanity loses, and Kira wins.

5. What If Levi Died in the Female Titan Arc? (Attack on Titan)

Without humanity’s strongest soldier, the Survey Corps’ morale collapses. Eren would spiral - losing his main mentor figure - and Mikasa would become even more protective, maybe even obsessive.

Erwin’s plans would fall apart without Levi’s surgical precision, meaning Annie might’ve actually escaped with Eren during that arc. And without Levi’s hand in later battles? No Levi vs. Beast Titan moment. No “dedicated to the cause” ending. Paradis might not survive long enough to even reach Marley.

6. What If All Might Never Found Deku? (My Hero Academia)

Without All Might’s blessing, Deku stays quirkless. The dream dies right there. But the darker twist? The League of Villains might recruit him.

A powerless boy resentful of hero society could’ve easily been molded by Shigaraki - and with Deku’s analytical mind, the League would have their strategist.

By the time All Might notices, it’d be too late. Deku becomes the anti-symbol of peace.

7. What If Gojo Stayed Sealed Forever? (Jujutsu Kaisen)

If Gojo never escaped the Prison Realm, the entire balance of the jujutsu world tips in Sukuna’s favor.

Yuuji’s morale crumbles, Megumi gets fully consumed, and the higher-ups lose their biggest deterrent.

But maybe, just maybe, this timeline leads to Nobara and Yuuji becoming legends in their own right, surpassing Gojo out of sheer necessity. Tragedy births legends, after all - and Gojo’s absence might be the ultimate catalyst.

8. What If Vegeta Was the One Sent to Earth? (Dragon Ball)

Replace Goku with Vegeta and you get a very different story.

To recap, Goku was sent to Earth to conquer it (at least before the retcon in Dragon Ball Super), and only failed in his mission because he hit his head as a baby.

Now, if it were Vegeta who was sent instead, he probably would have completed the mission and subjugated the human race. There would be no Z Fighters, no tournaments, and no Mr. Satan for comedy relief.

He also wouldn’t have ended up working for Frieza in the first place, and he could have confronted Frieza later on in the story out of revenge, and not out of goodwill towards the Namekians.

In fact, if Vegeta had confronted Frieza in Namek without Goku and succeeded, he could very well have taken the Namekian Dragon Balls for himself and wished for his own immortality instead, like what Frieza intended in the first place.

With Vegeta unchecked, who knows what would happen for the rest of the Universe.

9. What If Sanji Joined Blackbeard’s Crew? (One Piece)

Now that’s a spicy twist. If Sanji never crossed paths with Luffy and instead fell into Blackbeard’s orbit, the Straw Hats’ dynamic would be shattered from day one.

Blackbeard would instantly see Sanji’s combat potential - a mix of Observation Haki mastery and raw talent - and twist it to serve his darker ambitions. But over time, Sanji’s chivalry and moral code would clash with everything Teach stands for.

He’d probably start as a loyal fighter but slowly become the crew’s conscience, questioning their brutality until it all boils over.

The final act? Sanji turning on Blackbeard, taking half the crew with him, and building a new generation of pirates based on loyalty, not greed.

10. What If Shinji Never Entered the Eva? (Neon Genesis Evangelion)

It sounds simple - but if Shinji refuses to pilot Eva Unit-01, humanity’s fate changes instantly.

Rei would be forced to take his place, but without Shinji’s synchronization rate, the Angels might’ve wiped out NERV within weeks.

Ironically, this might’ve been a kinder fate for Shinji himself... but not for the world. Sometimes, the reluctant hero is the only one who can save everyone else.

Final Thoughts

The beauty of anime lies in its choices - and how fragile they are. A single decision, a single breath, can rewrite destiny itself.

From Minato’s sacrifice to Muzan’s madness, each “what if” reminds us how tightly the threads of fate are woven across the stories we love.
