Caesar Clown, also referred to as "Master" by his underlings, is a former colleague of Vegapunk and the primary antagonist of the Punk Hazard Arc. Caesar is the leading expert on chemical weapons of mass destruction and is a demented scientist that had a bounty of Beli300,000,000 on his head.
Caesar is, in Smoker's words, "one very crazy bastard", and his actions on Punk Hazard more or less validate the Marine vice-admiral's claim. A very cruel, arrogant, scheming, sinister, and overall a very evil person, Caesar takes great delight in causing harm and destruction to anything and anybody around him. His psychopathic nature is displayed many times, such as when he set off a chemical weapon on Punk Hazard, killing millions of its inhabitants and destroying its environment, selling or creating weapons of mass destruction for similarly unscrupulous individuals such as Doflamingo, performing sick experiments on children and drugging them with a lethal, addictive drug to ensure that they do not run away, and trying to murder everyone on Punk Hazard (Trafalgar Law, the Straw Hats, Smoker's Marines, the children, and his own (blindly loyal) minions) so he could test out his new poisonous gas weapon-pet, Smiley – all of which he does without a shred of remorse or empathy for his potential victims.
He appears to have a grudge against Vegapunk, as well as a cautious disposition, as shown when he hid from the Marines instead of trying to engage them immediately, as well as trusting Monet's deduction that the Straw Hats might be more powerful than their bounties claim, and waiting for Joker's approval to make his actions look like accidents, before starting attacks. Caesar is also a rather economizing person, as he did not want to waste the poison, by clearing it off but rather collected, saved and compressed it into Smiley.
He also appears unable to act or lie at times, often being seen overacting fake emotions when lying to his subordinates or the children, a trait that was quickly noted by Monet when he attempted to show false concern for his subordinates facing Smiley. However, with the blind trust of his subordinates and some crocodile tears, he was able to deceive them easily, leading them to believe that Vegapunk was responsible for the the Punk Hazard explosion four years ago. Caesar also is very ill-tempered and quick to anger when things do not go his way, such as yelling at his subordinates to let the gas come in to kill the intruders and his own men and again when Monet pointed out that Vergo would die and Caesar just yelled unconcerned about his potential disloyalty. Upon losing to Luffy, Caesar lost his composure and front for his subordinates, and ordered them to let in the Shinokuni gas while shouting out that they can easily be replaced, and then going as far as to personally kill the ones present simply to test out his newly acquired power.
Caesar BlushCaesar blushes after Chopper praises his creation of SAD.
He is a very prideful person, going as far to say that his work four years ago on the weapon that caused the Punk Hazard incident was not a failure, but instead was a great success, implying at a superiority complex. Due to his pride in his own work, he tends to blush when his work is praised, even by the enemy, but turned to indignity when that praise turned towards Vegapunk. He was also shocked to see Smiley not listening to him and eat the candy despite Caesar saying to wait and Caesar said it was alright while Monet noted he was not listening to him. He also does not take kindly to insults, as when Law called him stupid, Caesar lashes out by punching Law's heart. Unlike most Logia users, Caesar keeps his Devil Fruit ability activated all the time and is either completely or partly turned into gas.
Caesar Fault FaceOne of Caesar's many face faults.
Caesar has an odd habit of being easily shocked by things that leave him dumbfounded such as when Luffy survived his second Gastanet attack and appeared behind him unharmed, Caesar gave a comical face fault. He did so again when Luffy was about to attack him from behind in their second fight together, which seems to be a running gag on his part. Upon Luffy declaring that he does not want to see Caesar's face anymore out of anger, the scientist seemed hurt by the comment.
He also demonstrates tendencies of egomania when Luffy mentioned his Gasu Gasu no Mi had no effect on his immune system due to Magellan's Doku Doku no Mi, both being poisonous Devil Fruits of differentiating class, causing Caesar to become rapidly aggravated from the fact that Luffy compared his Logia powers to that of a "mere" Paramecia user. He was very surprised that his poisons did not affect Luffy due to the latter's immunity to poison given to him from his near-death poisoning by Magellan.
He has shown to have maniacal tendencies due to his sedulous research on weapons of mass destruction and his absence of emotion at the time of murdering people or provoking any type of suffering such as giving drugs to the children so they would suffer severe withdrawal and return to his research facility for more "candies" filled with the stimulant, and showing no regret or so
He also is very sadistic, as he exploited the blind trust of his wounded subordinates to test a newly developed gas and ordered the Yeti Cool Brothers to assassinate Brownbeard when he thought he was no use to him anymore: he further provoked a partially-paralyzed Brownbeard by revealing the truth about the gas explosion four years ago, in order to create an opportunity to have his subordinates to shoot him down. He also used the restricted drug NHC10 to maintain his control of the children he kidnapped, knowing that they will be unable to escape due to the agonizing withdrawal symptoms, and that by his own calculations, they will die in five years after he started his experiments with them, which he deems a necessary sacrifice for his science. Law found this aspect of Caesar disgusting. Caesar also seems to enjoy cocktails, as he is often seen holding a cocktail glass.
