Caesar Clown, often called “Master” by his followers, used to be part of a shady research group called MADS. His story is full of betrayal, lies, and big ambitions. Once upon a time, he worked alongside some of the smartest scientists in One Piece, including Vegapunk. But Caesar’s darker side got him in trouble. When his experiments became too dangerous, causing explosions and putting lives at risk, Vegapunk and the Marines kicked him out.
But, it didn’t stop him. Fueled by greed and a hunger for power, Caesar went rogue, doing experiments his own way. He worked with villains like Doflamingo and even Big Mom. His labs were packed with toxic weapons and risky experiments, especially on Punk Hazard, where he even used kidnapped children for his twisted research. “Mad scientist” barely covers it.
So, is he a bad guy? Yes, there’s no gray area when it comes to Caesar Clown. His actions are selfish, reckless, and cruel. He gases whole islands, experiments on kids, and barely cares who gets hurt as long as he gets what he wants. He’s got a long list of crimes under his belt, and there’s no sign of him changing any time soon.
Caesar’s Powers
Caesar Clown has the powers of the Gasu Gasu no Mi, or the Gas Gas Fruit, which is a Logia-type Devil Fruit. This gives him the ability to create, control, and even turn into gas. Caesar, with his cowardly personality, doesn’t make the most of this fruit, but it’s still terrifying.
Here’s how he uses his powers:
- Gas Form: Caesar can turn his body into gas, making it really hard to hit him. He can dodge most attacks this way, especially from anyone who can’t use Haki.
- Poisonous Gas Attacks: He can create poisonous gases to try and take down his opponents. He’s used this trick to fill whole rooms with poison, putting anyone without protection in serious danger.
- Explosions and Fire: With his gas powers, he can make flammable gases that he can ignite for big explosions. He can also remove oxygen from the air, which can suffocate anyone nearby.
- Shinokuni: One of Caesar’s deadliest inventions, Shinokuni, is a gas weapon that turns people to stone on contact. This isn’t part of his Devil Fruit power, but he uses his gas abilities to spread this weapon in terrifying ways.
Did Caesar Clown create a Devil Fruit? Not exactly. He didn’t invent any Devil Fruits himself, but he did manage to replicate some effects through his experiments. Caesar was involved in making SMILE, an artificial Devil Fruit that can give people animal-like abilities. These fake fruits were a big part of Kaido’s army, though they weren’t as powerful or reliable as the real deal.
Key Battles and Downfalls: Who Defeated Caesar?
Despite his brainpower and tricky abilities, Caesar Clown has been beaten more than once. His cocky attitude and over-reliance on his gas powers tend to get him in trouble. One of his biggest defeats was against Luffy on Punk Hazard. Luffy, angry at Caesar for experimenting on kidnapped kids, took him down with Haki-infused punches, proving that Caesar’s gas form wasn’t enough to protect him from strong opponents.
After Luffy beat him, Caesar’s status took a big hit. Trafalgar Law took control of him for a while, using Caesar’s scientific skills for his own plans against Doflamingo. Even Big Mom eventually captured Caesar, forcing him to continue his research for her benefit. He kept getting tossed around, shifting from a wanted criminal to a science tool for stronger people.
What Happened to Caesar Clown?
As the plan crumbled, Caesar found a way to slip away. He teamed up with the Vinsmoke Family and headed for the Germa Kingdom. There, he crossed paths with Vinsmoke Judge, a fellow ex-MADS scientist. Together, they launched NEO MADS, breathing life into a new research organization free from past constraints.
This new partnership with Judge gave Caesar a fresh start, a chance to rebuild his reputation in the world of illegal science. But given his history, it’s safe to assume that whatever he’s working on next is likely just as dangerous and morally questionable as his past projects.
Caesar’s experiments
Caesar’s work on SMILEs, artificial Devil Fruits, is one of his biggest and most dangerous projects. These man-made Devil Fruits were supposed to give people superpowers, just like the real ones. But Caesar’s process was far from perfect, and there’s a 90% chance that anyone who ate them would just get an uncontrollable laugh for the rest of their lives. Even if they don’t want to, or even if they’re sad, they’ll just keep smiling.
Hazardous Chemical Experiments and the H2S Gas
Another of Caesar’s creations was H2S gas, a deadly chemical weapon. He developed this toxic gas to prove he could turn hazardous materials into lethal weapons. In a horrifying display, Caesar once unleashed H2S on a whole island, killing countless people and making the land unlivable.
Experiments on Children
As if everything else wasn’t enough, Caesar also kidnapped kids from all over, telling their families he would cure them of a “disease.” In reality, he was testing a gigantification formula on them, trying to create a way to make humans bigger and stronger. His ultimate goal was to sell this formula to the highest bidder, no matter how much pain and suffering it caused his young test subjects.
Shinokuni
Caesar’s poison gas weapon, Shinokuni, also called the Land of Death, was his most ambitious and horrifying creation. This gas could petrify anyone it touched, turning them into lifeless statues. Although it had some limitations and took half a day to take full effect, it was still a terrifying weapon.
