Mayuri is a mad scientist in the most literal sense. His habits are creepy, strange, and unforgettable. He experiments on people, treats his own body like a test subject, and often talks in a strange, sing-song voice. You never really know if he’s joking or planning something horrible.

Mayuri also changes his appearance often, paints his face like a doll, and loves testing new inventions, but on real people. Mayuri is weird from head to toe. But in the world of Bleach, his madness is also what makes him dangerous. He's not just strange, he's terrifyingly smart too.

9/10 Yumeko Jabami - Kakegurui

Yumeko is not just any gambler, she’s addicted to it. But here’s the twist: she doesn’t gamble to win money. She does it because she enjoys the risk. The higher the stakes, the more excited she gets. And yes, she even blushes during intense bets. That’s how far her love for gambling goes.

Her weird habit of enjoying danger is what makes her so intense to watch. Yumeko is calm, polite, and beautiful, but once the games begin, she turns into someone else. Her glowing red eyes and wild smiles will creep you out. She’s one of the most unique anime characters with an intense aura, and her weird habits are a big reason why.

8/10 Jiraiya - Naruto

Next on the list, we have Jiraiya - the legendary pervy sage. He’s a powerful ninja, a great teacher, and also a shameless peeper. His habit of spying on women in hot springs is not exactly heroic, but it’s definitely memorable. He even writes books about it!

Despite that, he’s one of the most loved characters in the show. He’s funny, wise, and always full of surprises. His weird habits don’t define him, but they sure make him stand out. Only Jiraiya could balance being a pervert and a mentor in the same episode.

7/10 Ken Kaneki - Tokyo Ghoul

Kaneki’s weird habit started after being brutally tormented by Jason. He begins cracking his fingers in this creepy, slow way, and it’s actually something picked up by his consciousness, as Jason broke his fingers and ripped out his nails. Every time he does it, it sends chills down your spine.

6/10 Gintoki Sakata - Gintama

Gintoki might look lazy and messy, but he’s one of the funniest and most unpredictable anime characters ever. His biggest weakness? Sweet things. This man can’t go a day without eating parfaits or drinking strawberry milk. He also reads Weekly Shonen Jump like it’s the Bible.

But what makes Gintoki even weirder is how random he is. He can go from sleeping on the floor to giving the most serious life advice in seconds. He jokes around all the time, breaks the fourth wall, and acts like the main character, even when it doesn’t make sense. But hey, isn’t that what makes him amazing?

5/10 Levi Ackerman - Attack on Titan

Levi is known as humanity’s strongest soldier, but did you know he’s also a clean freak? Seriously, he can’t stand dirt. After fighting Titans, his first worry isn’t injuries, it’s how dirty everything is. He even yells at people for leaving crumbs.

But his obsession with cleaning is kind of amazing. It adds a strange but funny twist to his serious character. You can trust him to kill a Titan and then wipe the floor afterward. Maybe the real reason Titans are scared is because Levi might mop them out of existence.

4/10 Naruto Uzumaki - Naruto

Next on the list, we have Naruto, a guy full of energy and weird habits. Naruto says “Dattebayo!” about 200 times in every episode. The funny part? “Dattebayo” doesn’t even mean anything; it’s just his thing. But somehow, it fits him perfectly.

He also has a habit of jumping into fights without thinking and shouting things at full volume. And let’s not forget how often he uses his Shadow Clones for ridiculous stuff. But these weird habits are also what made us love him. He’s loud, weird, and totally unforgettable.

3/10 L - Death Note

L isn’t your usual genius. He solves the biggest cases in the world, but the way he does it is far from normal. First of all, he never sits like a regular person, he squats on chairs like a frog. He also holds things with just two fingers, like they might bite him. And let’s not forget his love for sweets. Cakes, candy, sugar cubes - if it’s sweet, he wants it.

But L’s weird habits are part of his charm. The way he talks, moves, and even looks at people is strange. Yet somehow, it works. His odd behavior actually helps him focus better. Maybe next time you're working hard, try sitting like a frog and eating cake. Who knows, it might boost your brain too.

Near is another genius from Death Note, and just like L, he’s got his own set of strange behaviors. He loves playing with toys, robots, action figures, puzzles, you name it. You’ll often see him building towers of dice or spinning things between his fingers while solving big cases.

He also plays with his hair, sits in weird positions, and talks in a very quiet voice. But behind all those odd habits is a sharp mind that can solve anything. Near is proof that even the quietest, weirdest person in the room might just be the smartest.

1/10 Hisoka - Hunter x Hunter

Hisoka is something else - literally. He's not just one of the anime characters with weird habits, but he's bizarre in every sense. He fights like an artist and treats battles like a game. But the strangest thing? He gets way too excited when facing strong enemies. And by excited, we mean erotic - his face says it all.

Hisoka also has this habit of licking his lips, smiling at the wrong time, and acting super creepy. But that’s also what makes him so unforgettable. He’s a magician, a fighter, and a total wildcard. Watching him is like watching a ticking bomb; you never know what he’ll do next.
