Renji Abarai

Renji Abarai is a Shinigami. Alongside his friend and partner Chad, Renji traveled dimensions picking up bounties until they met Ichigo Kurosaki who then convinced them to assist him to sell the Orb for a massive project. However as it was discovered that the Orb was one of the Dragon Balls which was being sought out by the Klaxisaur Princess, Renji was convinced to risk everything to stop the Klaxisaur Princess' plans to destroy the Soul Society and enslave the world. During the ensuing conflict, Renji managed to assist his friends in destroying the Klaxisaur Princess, despite Chad seemingly being killed. He then became a member of the Soul Guardians alongside Chad.

Renji continued working with the Guardians when they were hired by the Kais to slay a monster, however Renji took the job as a way to steal Kai goods to sell. This angered Supreme Kai who declared war on the Guardians, hiring the Soul Reapers to capture them. Renji and Chad were soon captured by the Soul Reapers, who had taken command from Kenpachi, which forced Renji and Kenpachi to work together to break free and kill the rogue Soul Reapers. During his time with Kenpachi, Renji learned how to be a better person and understood how much he loves his Guardians family, so he joined the fight against Papa, the father of Ichigo, losing Kenpachi during the battle.

Four years later, the Guardians picked up Son Goku after he and his people were attacked and slaughtered by Omega Shenron, who had resumed his quest for the Dragon Balls himself. The Guardians split up in order to procure different Balls; while the rest of the team returned to Wa-ria to find the Dragon Ball there, Renji and Chad accompanied Goku to Xeno's Throne to obtain Mastered Ultra Instinct. The trio then headed to Earth where they helped the Jump Force in defending Shura from Omega Shenron's minions. Their efforts to stop Omega Shenron proved for naught in the end, and Renji was one of the only Guardians to survive Omega Shenron's subsequent mass slaughter, along with Byakuya.

Abilities
Master Swordsman: Renji is highly skilled in various swordsmanship techniques.

Whip Mastery: What makes Renji so effective in battle is the unique method in which his Zanpakutō operates; Zabimaru is an amalgamation of a whip and a sword. Renji is a versatile fighter because of this, and to effectively wield it is a testament to his skill.

Shunpo Expert: Knowing that Zabimaru's Shikai attacks leave him open to counter-attacks, Renji has become very proficient in Shunpo to compensate for this weak point.

Zanpakto: Zabimaru
 * Zabimaru's sealed form resembles a typical katana. It has a rectangular bronze tsuba with a jagged design, and a red handle and sheath.
 * Shikai: Its Shikai command is "Howl". In its Shikai, Zabimaru transforms into an even longer 6-part segmented blade; each segment is wider than the one preceding it from the hilt, with 2 pick-like protrusions on the front and back of each segment, with the ones on the front much longer than the ones on the back. The segments of Zabimaru can grow in number almost without limit. The segments are connected by a stretchable thread, making Zabimaru more useful as a whip than an actual sword, however, it can serve as a regular sword just as easily, thanks to Renji's swordsmanship. Its guard and handle remain the same in its Shikai release.
 * Bankai: Sōō Zabimaru (双王蛇尾丸, Twin Kings Snake Tail; Viz "Two Kings"): The true form of Renji's Bankai takes on a more compact form that is predominately worn. On his right wrist, Renji gains a gauntlet resembling the top portion of a snake’s skull, with a cowl of red fur surrounding its base. A long, bony tail composed of vertebra-like structures protrudes from the back of the skull, trails behind him and hangs around his waist like a loose sash. At will, Renji can extend a large blade from the snake’s mouth. Renji also gains a large cowl of light fur that hangs down from his left shoulder. Additionally, he gains a pair of pauldrons that form an armored collar, as well as additional vertebral cords that hang down from his waist.
