Babanuki is an extremely large and muscular man with long dark hair and a large beard. Like many other SMILE users, he has two horns on the top of his head. He wears dotted metal plates on his arms, a belt with a large round buckle, and dark pants. Due to the consumption of a SMILE fruit, he has an elephant's head on his chest.
As warden of the Prisoner Mine, Babanuki is quite cruel, telling Hyo that if he cannot earn food by undergoing the prison's grueling work, he should die like a real man. He is not sympathetic to the prisoners and will often blow off their actions as insignificant due to the immense power he and his subordinates hold over them. He takes running the prison quite seriously, but he can also be slightly dim-witted, as he did not pay much mind to Luffy's attempted escape and he and his subordinates had to be spurred into action by Queen. However, he can also be more reasonable and level-headed than his superior as he tried to remind Queen of how dangerous it is to get between Big Mom and her food after Queen insulted and threatened her and later ordered his men to not shoot at Big Mom, knowing that it would only anger her. The elephant growing out of his body seems to like bananas, casually eating some while his master was giving out orders.
After being tamed by Tama, he becomes friendly and loyal to her as shown when he gave a false report to Queen.
Abilities and Powers
As warden over the Prisoner Mines and a Headliner, Babanuki has the greatest amount of authority among the people there, having power to give orders to other members of his crew and overseeing the subjugation of the prisoners. So far, it only seems as though he answers to his general, Kaido, and the All-Stars, namely Queen.
Babanuki ate an elephant SMILE, which caused an elephant's head to grow out of his chest. Unlike some other SMILE users, Babanuki appears to have full control over his elephant head, having been seen speaking through it. However, it can still act independently at times. The elephant head is capable of unleashing powerful explosive blasts of air out of its trunk. However, the trunk can be tied, which prevents the sneeze from being discharged, it will backfire on Babanuki, causing him grievous injuries.
- Elephant Hakkushon (
象の鼻息Erefanto Hakkushon?, literally meaning "Elephant Nasal Breathing"): Babanuki's elephant unleashes a massive sneeze that can fly a great distance and create a powerful explosion upon impact. The explosion was strong enough to stun and slightly injure Luffy, albeit while he could not use Haki. He can also use this technique to launch cannonballs, with the trunk serving as a makeshift cannon. This is called Elephant's Marchoo in the Viz Manga. Hakkushon is the Japanese onomatopoeia for sneezing.
He possesses a weapon called "Excite Shot", which is said to be 200 times more deadly than the "Mummy virus" from the "Excite Bullet". He attempted to fire this with the elephant's trunk, only for Luffy to foil his plan.
Wano Country Arc
Babanuki watched as Daifugo punished Hyo for possessing meal tickets he did not earn, and he told Hyo that he should die if he could not work for his food. Babanuki then saw Monkey D. Luffy attack Daifugo, and he was stunned at how powerful the attack was despite Luffy being weakened with Seastone handcuffs. He moved to kill Luffy immediately, and hit him with an explosive elephant sneeze. Queen then arrived to talk with Babanuki, and Babanuki told him about the issues happening in the prison, including Luffy attempting to escape at that very moment. However, Luffy and Hyo were eventually caught and brought before Queen.
When Big Mom arrived at the Prisoner Mine, demanding oshiruko, Babanuki tried to reason with an angered Queen by telling his superior that it was not a good idea to fight against Big Mom simply over food. After Big Mom overpowered Queen, Babanuki told Daifugo not to provoke her. He then asked for Kaido's orders only to learn that Udon's communications were disabled. He was later shocked when he saw Luffy remove his and Hyogoro's collars.
As Big Mom chased Luffy through the Prisoner Mines, Queen got back on his feet and told Babanuki of his plan to subdue Big Mom. When she came back, Babanuki watched as Queen attempted to attack Big Mom by slamming into her head in his brachiosaurus form. The attack did not inflict any significant damage, but Big Mom fell asleep immediately afterwards. After Big Mom was wrapped in Seastone chains and injected with heavy doses of anesthesia, Queen left Babanuki in charge of the prison before taking Big Mom to Onigashima. Right after Queen's departure, Babanuki noticed that Luffy was still free.
As Luffy took on the Beasts Pirates rushing to attack him, Babanuki ordered the prisoners to help subdue him. When someone inside a cell shouted out to Luffy, Babanuki revealed to his men that the voice came from Kawamatsu. After Raizo freed Kawamatsu, Babanuki ordered his troops to prepare Excite Bullets and get into battle formation. When Kawamatsu, Hyogoro, Raizo, Luffy, Chopper, and Kikunojo gathered together, Babanuki remarked that this felt very much like what Orochi had been paranoid about. He said that he would need to contact Kaido, but Kikunojo said that they would silence him and his forces first.
As Daifugo shot at the prisoners with the Excite Bullets, Babanuki ordered the prisoners to spread the disease at Luffy and his allies, but Luffy fearlessly shoved off the infected carriers and ignited the prisoners' spirit. Worrying that Luffy was swaying the prisoners to rebel, Babanuki attempted to use a cannonball-size Excite Shot. However, just before he fired, Luffy's advanced Kenbunshoku Haki enabled him to stop Babanuki just in time by tangling the trunk of his elephant as he was about to fire. The shell then exploded inside Babanuki's body, defeating him.
- Babanuki (ババ抜き?) is the Japanese name for the card game Old Maid, fitting with the card game-themed names of the Beasts Pirates Headliners.
