Byakuya Kuchiki

Byakuya Kuchiki is a Shinigami assassin, an adopted son of the intergalactic warlord, Omega Shenron and adopted brother of Rukia Kuchiki. As the right-hand man of the Klaxisaur Princess during her and Omega Shenron's quest to retrieve the Orb, he helped him in the fight against the Soul Society and the Soul Guardians. He vanished after a fight against his sister. Byakuya soon afterwards was captured by the Kais and handed back to the Guardians. He escaped and helped the Soul Reapers in a mutiny against their former leader Kenpachi before leaving to find and kill Rukia. After forgiving and helping his own sister alongside the Guardians during the Battle on Papa's planet, he left in a ship to pursue a revenge mission against Omega Shenron.

Byakuya was eventually captured by Omega Shenron, however, and used as a bargaining tool to convince Rukia to reveal the location of a Dragon Ball. Escaping and then pursuing Omega Shenron to a barren planet, Byakuya learned that Omega Shenron had killed Rukia and aided both the Guardians and members of the Jump Force in combating Omega Shenron. Despite their efforts, they failed to stop Omega Shenron from obtaining the Dragon Balls, which he then used to wipe out half the universe's population. Byakuya was among those who survived, but was left alone on the planet with Edward Elric. He and Renji Abarai are currently the only remaining members of the Soul Guardians.

Abilities
Master Swordsman: Byakuya is a master of swordsmanship, possessing flawless precision and performing lethal attacks with little effort.

Shunpo Master: Byakuya is arguably best known for his skill in Shunpo. Having been taught by, but never beating "Goddess of Flash" Yoruichi Shihōin, he is easily one of the most proficient users of this skill in all of Soul Society.

Senka (閃花, Flash Blossom): A Shunpo technique where one, moving to their opponent's back, directly attacks and seals one's "Saketsu" and "Hakusui" in two rapid strikes, effectively cutting them off from their spiritual energy flow. This attack is his favorite to use.

Kidō Master: Byakuya has considerable knowledge of high level Kidō spells, casting several in quick succession, with no incantation and almost no effort, and still possessing formidable power.

Master Tactician: Byakuya is a highly perceptive fighter, almost immediately determining an opponent's attack patterns and weaknesses.

Immense Spiritual Power: He can exert an immense amount of Spiritual Pressure, which, in addition to his already admirable combat skills and finesse, makes him one of the most formidable captains. His spiritual pressure can be felt from a great distance, and it has the tendency to make people perspire in fear.

Zanpakto: Senbonzakura
 * Senbonzakura is a regular katana. It has a simple cross guard, with an open frame much like a four-pane window. It has a bronze guard, with lavender hilt-wrapping, and a white sheath.
 * Shikai Special Ability: In its Shikai, Senbonzakura's blade separates into a thousand tiny, slender blade fragments, which fly away from the hilt, leaving only the sword's handle in Byakuya's hand. While the blades are supposedly too small to be seen normally, they reflect light in such a way as to resemble cherry blossom petals. By swinging Senbonzakura's hilt, Byakuya can control the blade fragments, allowing him to shred opponents at a distance and break through almost any defense.
 * Bankai: Senbonzakura Kageyoshi (千本桜景厳, Vibrant Display of a Thousand Cherry Blossoms): Byakuya's Bankai is a much larger version of Senbonzakura's Shikai. To activate it, Byakuya drops his sword straight down. The sword phases into the ground, as though it were a pool of water. Energy ripples expand out, turning the surrounding area dark, and within seconds, two rows of a thousand giant blades rise up from the ground. Those thousand swords scatter, and countless flying blades pierce the enemy. No one knows the exact number of blades generated, and no one can dodge or even see the movements of these blades.
