Shachi is an average sized lean man with red (brown in the anime) hair that reaches his shoulders. Like most of the Heart Pirates he wears a beige overall, with their Jolly Roger displayed on the back and the chest pocket, as well as brown boots. He wears a blue hat with a red brim and is always seen wearing sunglasses. There is also a tattoo located on his forearms.
After the timeskip, Shachi wears a new hat that resembles his namesake animal, which is a killer whale (also known as an orca).
In Wano Country, he wore a dark yukata (light green in the anime) with the Heart Pirates' jolly roger on each sleeve near the shoulder. He also carries a sword on his left hip.
Abilities and Powers
He has not yet been seen fighting in the manga, but in the anime, he has been seen using martial arts and is quite proficient at it.
In his childhood delinquent days, Shachi was depicted with a baseball bat.
Shachi was born on Swallow Island in the North Blue. He and Penguin were orphaned at a young age after their parents were killed in a tsunami. They had been sent to live with Shachi's aunt and uncle, who treated them like slaves and made them do illegal activities. One day, they ran away and lived in a shack in the forest.

At some point, Shachi and Penguin met the polar bear mink Bepo and beat him up. Law, who was out on a walk, found them and confronted them. Law knocked both of them out with his Devil Fruit powers.
Sometime later, they gathered fruits in the forest and encountered a boar that pierced Shachi in the stomach. Penguin tried throwing a bomb that they stole, but it exploded before he could, and the boar severed Penguin's right arm. Law and Bepo saw the explosion and brought them to Wolf's farm. Law had Bepo stopped their bleeding, but the two had lost so much blood that they needed transfusions. Wolf offered to give his blood to both of them despite the risk. Law then went to work on reattaching Penguin's arm, and after several painstaking hours, he successfully completed the operation and collapsed. Shachi and Penguin recovered, and Wolf was fine. After waking up, Penguin discovered that he could use his severed arm again, and he and Shachi thanked Law.
A week later, Shachi and Penguin recuperated, and they told Wolf and Law their names and history. Shachi said that he did not know the point of living, which reminded Law of his own experiences. Law then offered for Shachi and Penguin to become his subordinates and live with him and Wolf, to which Wolf reluctantly consented to, and they accepted.

Summit War Saga
Sabaody Archipelago Arc
After a long voyage following one of the Log Pose routes of the Grand Line, Law and his crew came to the Sabaody Archipelago to prepare themselves for the New World. He was seen standing behind his captain as he talked to X Drake.
He is later seen with his captain at the Human Auctioning House, to observe the auction taking place. After interruptions by Luffy, the Heart Pirates found themselves fighting to escape, alongside Eustass Kid's and Luffy's crews, in the face of a daunting Marine attack.
Alongside the rest of his crew, Shachi fought against one of the Pacifista; though the outcome of this battle was not seen, they eventually managed to escape.
During the Summit War of Marineford, the Heart Pirates and Shachi were initially present on the Sabaody Archipelago where the broadcast of Ace's execution was being shown. He was presumably watching the events at Marineford unfold, along with the Supernovas and they set sail immediately after the broadcast was cut. He can be seen on the Heart Pirates submarine as they emerge towards the end of the war to pick up a critically injured Luffy and Jinbe.
After Rayleigh arrives on the island, the Heart Pirates leave and Shachi expresses his disappointment about not getting a chance to see inside the all-female kingdom.
Later, out in the open sea, Law explains about waiting for the right time to enter the New World. Law tells his crew to follow his orders so he can steal the proper throne. Shachi and his crew mates cheer for their captain.
When Law arrived at their location, the Heart Pirates were overjoyed to be reunited with him.
After the Straw Hats returned to the Whale Forest, the Heart Pirates greeted Luffy but were then furious when Luffy and Law went on having a private conversation. The Heart Pirates and Luffy's crew (except Franky, Robin, and Brook) then partied with Nekomamushi and his subjects.
Wano Country Arc
After leaving Zou, the Heart Pirates infiltrated Wano Country. On top of a mountain, Bepo, Shachi, and Penguin spotted Luffy and Zoro through binoculars as the latter two entered Okobore Town. When Luffy and Zoro were heading to Bakura Town in pursuit of a Gifter that abducted a little girl, the trio informed Law about the situation.
On the way to Bakura Town, Bepo ate a fish from the polluted river and got sick, causing some delay to Law's group. Shachi then informed Law that Basil Hawkins was approaching the town and there was a fire. After Luffy and Zoro wreaked havoc at Bakura Town, Shachi and Penguin met up with Law and Luffy's group at the ruins of Oden Castle.
Shachi was then seen sitting outside as Kin'emon told Luffy's group about Wano's past. He then witnessed Kaido's arrival to the Kuri region. After Luffy rushed off with Law following him and Kin'emon and Kiku left to rescue Tsuru, the rest tried to escape as Kaido approached the castle and destroyed it with a fire breath. Shachi and the other males in the group were saved by the kunoichi Shinobu's jutsu which sunk them into the ground.
Sometime after this ordeal, Penguin worked to deliver Kin'emon's secret message to his allies. Penguin, Shachi and Bepo were later captured by the Beasts Pirates and incarcerated in the Rasetsu District Prison to be used as bait for Law. When Law took the bait and appeared, Hawkins then demonstrated his ability on Shachi as Penguin looked on with concern. The trap, however, did not work as intended, and Law remained resolute in cutting Hawkins down regardless of his or his crewmates' lives, prompting Hawkins to rethink the situation. As a result, Bepo, Shachi, and Penguin were released by Hawkins, who made a deal with Law for their freedom in exchange for his capture. Law ordered his subordinates not to tell Luffy about this in order to not compromise their plan for the eventual raid. The trio later met up with Nami at Ebisu Town and gave her Kin'emon's secret message now drawn with two lines on the snake as Shimotsuki Yasuie's last message. After Nami left, the Heart Pirates discussed their captain's situation.
Once Law managed to escape from the Flower Capital, Penguin and the rest of the crew reunited with their captain at some point and entered the battle with the Beasts Pirates on the day of the Fire Festival. After rescuing Kin'emon's group, the crew was shocked to hear that Kaidou formed an alliance with Big Mom. Following the takedown of the guards at the torii gates by the Straw Hat Pirates, the Heart Pirates and the Scabbards (except Kin'emon and Denjiro) traversed to the back of Onigashima in the Polar Tang, avoiding the myriad of whirlpools along the way. When the submarine got close enough, it rose to the surface and Law teleported himself, Bepo, Shachi, Penguin, and the Scabbards with them to Onigashima's back entrance.
Penguin was later seen inside Kaidou's castle during the all-out attack on the Beasts Pirates. Later on, Penguin heard Sanji's cry for help as it was broadcasted throughout Onigashima, and though bruised, still kept fighting as the raid kept going on. Penguin and his two crewmates eventually met up with Franky at the Right-Brain Tower, joining forces with him to prevent enemy reinforcements from getting into the Skull Dome's Live Floor.
