Due to his actions, he is a major antagonist of the Whole Cake Island Arc.
Katakuri is a large, muscular man with short spiky black hair and two symmetric scars on both sides of his face. He has long legs, with his thighs being equally as long as his lower limbs. He has sharp, intense eyes, highly arched eyebrows, and prominent lower eyelashes under each eye. He wears a massive light ragged scarf that covers his mouth and reaches his shoulders. He also wears a torn leather jacket that exposes most of his torso, dark gloves and pants, a belt with a skull-shaped buckle, and spiked boots with spurs. His torso is covered in tattoos, and he wears spiked bracelets on his arms as well as knee pads with a single spike on them.
Katakuri has a very serious, no-nonsense demeanor, caring greatly about his crew and family's objectives. With his heightened Kenbunshoku Haki allowing him to see a little bit into the future and make smart judgement calls, he is dedicated to efficiently dealing with all possible threats within his vicinity, and is thus among the few Charlotte children that can be seen taking action without instructions from Big Mom herself. This is shown when he quickly dispatched Jigra after foreseeing his assassination attempt on his mother, or when he promptly decided to take out Sanji by himself when he foresaw the original assassination plan failing, not waiting for Big Mom to decide upon what to do. However, this impetuousness can sometimes get the best of Katakuri, as he unwittingly sabotaged Big Mom's plan after acting too fast. Katakuri is able to recognize his shortcomings and will act pragmatically should he realize he is at a disadvantage. He has a tendency to foresee what other people say and respond to them before they actually talk. However, his usual calmness can be shaken when he foresees a horrifying future as seen when he went pale in pure fear of the events lying ahead.
He also seems to have a caring side which was revealed when he used his Devil Fruit powers to create ear plugs not only for himself but also for his fellow siblings. This side is shown again when he was quick to rescue his sister Charlotte Brûlée from her captors, though this may have been done to prevent their enemies from using her any further in their plans as he did grab her neck in a threatening way and express his annoyance at how much use they put her to. 
Katakuri is shown to be very loyal to his mother as he would not hesitate to eliminate anyone who would threaten her. When the wedding ceremony was about to get hectic, Katakuri immediately leapt in front of his mother to protect her from harm. Despite his loyalty and devotion to her, Linlin sees Katakuri as a lowly child and will not tolerate him interfering with her business. Katakuri merely accepts being patronized by his mother but will also explain himself to her as shown when he provided his reason for attacking Luffy.
When Bege attempted to attack his mother with Big Father's cannons, Katakuri clogged up the cannon barrels with mochi, effectively protecting Big Mom while she was vulnerable.
Initially, Katakuri seemed very respectful towards Bege as he prevented two of the latter's crewmates from being killed before the ceremony by Jigra. When the Straw Hats caused trouble for the wedding, Bege subdued Luffy before noticing that Katakuri had foresaw a terrible future. When the Sweet Commander ordered him to kill Luffy, Bege refused and instead ordered his allies to put in their earplugs to avoid Big Mom's screams. Katakuri realized Bege's betrayal when he attempted to shoot him but he was unharmed and tried but failed to prevent Luffy from showing Carmel's broken picture to Big Mom. After Bege's assassination attempt on Big Mom failed, the latter was forced to transform into a giant fortress to save himself and his allies. 
Straw Hat PiratesEdit
Katakuri made an enemy out of the Straw Hats when he attempted to kill Sanji himself after he foresaw Pudding's failure in her task and Sanji dodging the priest's shot. However, his own attempt on Sanji's life failed earning him a glare from the Straw Hat Cook and the only thing he could do next was to prepare for the chaos caused by the duplicates of Luffy. After the real Luffy entered the venue, Katakuri prevented him from destroying the portrait of Carmel, which hindered his group's plan to assassinate Big Mom and rescue the Vinsmoke Family. He later ordered Bege to kill Luffy after the latter managed to tackle him, but Bege refused when he saw that Katakuri foresaw a terrible future. Katakuri tried to prevent Luffy from showing Big Mom the destroyed portrait of Carmel and in spite of his efforts to restrain Luffy, the Straw Hat Captain managed to show Big Mom the portrait and left Katakuri incapacitated. After Bege's assassination attempt on Big Mom failed, Katakuri provided his siblings with earplugs and they surrounded the Straw Hats and their allies. 
Abilities and PowersEdit
As a Sweet Commander, Katakuri's authority in the Big Mom Pirates is second only to Big Mom herself. His bounty of 1,057,000,000 proves that the World Government views him as an extreme threat. Even Capone Bege of the infamous Worst Generation considers him a monstrous threat.
Katakuri has tremendous physical strength, being able to flick jellybeans with enough force and velocity that they function similarly to bullets. Even from a very far distance, Katakuri can easily kill a man sitting atop a gigantic wedding cake with a flicked jellybean. He also has considerable accuracy, as he managed to hit Jigra from so far away that Bege did not even notice him, and later would have hit Sanji as well had the latter not dodged at the last moment. He is incredibly fast in launching his attacks as Monkey D. Luffy, an expert Kenbunshoku Haki user, barely had time to react to Katakuri's attack. He is shown to have a strong will, being able to withstand a burst of Big Mom's Haoshoku Haki and remain conscious from her loud scream.
- Further information: Mochi Mochi no Mi
Katakuri ate the Mochi Mochi no Mi, a Logia-type Devil Fruit that lets him turn any part of his body into mochi, which has strong adhesive properties. He is capable of wielding massive amounts of the substance as a large blunt weapon, though it loses its effectiveness when exposed to moisture.
Katakuri has trained his mastery of Kenbunshoku Haki to such a degree that he can see slightly ahead into the future. He was able to detect and instantly thwart an assassination attempt on Big Mom and her affiliates that would have been carried out moments later by a vengeful guest invitee. His predictions were shown to be accurate when he justified his killing of the guest to Bege and knew word for word how the latter would respond to him. Bege recognized him as the greatest obstacle to his own assassination plan.
The future events Katakuri sees can be changed, which he often attempts to do so himself, as shown when he prevented Jigra from carrying out the assassination plot he foresaw. However, changing the future may not solve anything or make things worse, as shown when he tried to shoot Sanji. Other people are also capable of changing the foreseen future. However, he is unable to see the cause of his foresight, and was confused as to why Pudding was crying at the altar.
Katakuri wields a trident in battle. He is first seen wielding it during Vinsmoke Sanji and Charlotte Pudding's wedding ceremony. He has also been shown flicking jellybeans with such velocity that they function similarly to bullets fired from a gun.
Whole Cake Island ArcEdit
On the wedding day, Katakuri was on the roof of the Whole Cake Chateau as a man named Jigra attempted to get into the wedding without going through a body check. Katakuri, seeing that Jigra actually intended to take revenge on Big Mom and attack the venue, shot the man down as he was talking to Capone Bege. Katakuri asked Bege if he thought it was wrong of him to do that and told him to tell Big Mom that it was his judgement to kill Jigra.
After the wedding began, Katakuri was seen eating and getting acquainted with some guests. While Pudding and Sanji stood on the altar, Katakuri foresaw Pudding breaking down in tears, much to his confusion. When that event happened, Big Mom signaled the priest to assassinate Sanji. Knowing that Sanji would dodge the shot, Katakuri tried to kill Sanji himself by launching a jellybean at him. However, to his surprise, Sanji managed to evade the attack and it hit the priest instead with Sanji glaring at Katakuri for his action. Having failed to kill Sanji, Katakuri then stood close to Big Mom, preparing for the chaos that was going to happen.
As duplicates of Monkey D. Luffy were unleashed into the venue, the real Luffy attempted to break the photo of Carmel. Katakuri stopped him with his Devil Fruit powers and immobilized him. When Big Mom was accusing him of interfering with her business, Katakuri informed her of Luffy's intentions before demanding to know how Luffy knew about the photo. Jinbe then freed Luffy using black tea before claiming that he was the one who told Luffy about the photo.
In the ensuing conflict, Katakuri foresaw a horrific future and approached Luffy and Bege. He ordered Bege to kill Luffy, but the latter outright refused before initiating his plot to assassinate Big Mom. As Katakuri went after Luffy, he told Charlotte Perospero to shoot the Vinsmoke Family to death. Bege tried to hold Katakuri back by shooting him, but the bullets had no effect on him due to his Logia powers. Jinbe and Pedro then tried to fight him, but he managed to get past them and used his ability to pin Luffy down. However, despite his efforts, Luffy managed to show Carmel's broken portrait to Big Mom, causing her to start screaming.
After Bege's assassination attempt failed, Katakuri created earplugs with his powers and distributed them to his siblings. They then surrounded Luffy, Bege, and their allies before Bege transformed into a giant fortress.
As Luffy's group and the Vinsmoke Family ran into the fortress, Katakuri used his ability and grabbed Brûlée from Caesar's back. He then used his jellybean bullets to attack several members of the Fire Tank Pirates. Katakuri later used his ability to plug the cannons in Bege's fortress, preventing them from firing at Big Mom. He was then seen with his siblings, awaiting their enemies' next move and remarked to Brûlée on how her captors used her in their plan, but she replied that she was the victim and told him to make their enemies pay.
