Blueno

Standing very tall, Blueno is marked by thick lips, a dark beard, and hair shaped into two points that mimic a bull's horns. His tending days had him in an apron worn over a yellow shirt covered in black dots, while his life as a government agent put him in a dark two-piece suit, a sweater beneath it, and a white square folded into his breast pocket. When tailing Robin and moving on Iceburg, he hid behind a checkered cloak strung with beaded necklaces and a pair of masks worn one after the other: first a painted face lined from the eyes across the cheeks, then a drowsy, grinning bear. An Oda sketch of the unit as kids shows a younger, beardless Blueno in a striped tee and shorts, holding a baseball bat and glove, since the sport was a childhood love of his.

Through five years of cover work he played a warm, modest barkeep, then dropped the act to expose the same icy devotion to government justice that defines his unit. What separates him from teammates such as Lucci, Kaku, and Jabra is his constant composure; he stays level-headed almost without fail, which reads as his real nature rather than an act. In that way he stands for the cold machinery of the World Government, having helped pressure Robin using wounds the Government itself had dealt her. Analytical and watchful, he was the only agent to notice that Spandam's snail had slipped off its hook and to sense something was wrong at Enies Lobby. He trusts his own strength and Six Powers deeply, was shaken when a pirate held even with him, and rejects unproven claims, brushing off Jabra's belief that devils live inside Devil Fruits.

Shrewd and patient, Blueno held his barkeep disguise for roughly five years while quietly combing the city for the Pluton plans without drawing notice. Harsh Six Powers conditioning earned him a Doriki of 820 and crushing power: he leveled the Galley-La shipwrights, dropped Tilestone with one punch, and dragged three train cars into a violent collision with a single whip pull. Quick through Soru and tough enough to weather Sanji's steel-splitting kicks plus a full Gear 2 assault, he placed fourth in his unit's rankings. His Tekkai counts among the group's strongest, and he created mobile versions such as Rin. His Devil Fruit lets him carve openings into any barrier, regardless of how thick or sturdy it stands, with each door eventually shutting on its own; he slips into locked spaces, pins an enemy's feet with tiny doors, tears portals in the air that reach a separate dimension, and once spun a door across Luffy's face to leave him dizzy. He also wields Armament and Observation Haki.

A native of the North Blue, Blueno drilled as a CP9 hopeful on Guanhao roughly twenty-four years ago, schooled in the Six Powers discipline and the killer's trade beside Lucci and Jabra so the children could grow stronger than justice itself. Seven years before the present, four agents embedded in Water 7: Lucci, Kaku, and Kalifa joined Galley-La, while Blueno ran a bar. Their aim was the Pluton blueprints held by Iceburg, who had unknowingly already passed them to Franky. Acting the friendly tender, he grew close to Franky and Paulie before the unit struck Iceburg for the plans, and his fruit featured in both attempts on the shipwright's life; during the second he easily put Tilestone down.

The agents burned the mansion to frame the Straw Hats, then later seized Franky and Usopp. Aboard the Sea Train he fended off Sanji, Franky, and Sogeking and carried Robin away through an air door. At Enies Lobby his suspicion about the off-hook snail proved right, sending him to face Luffy on the courthouse roof, where Luffy cracked his Tekkai, matched his Soru, and unveiled Gear 2 for the first time, eventually knocking him out in a delayed collapse. After the Buster Call wrecked the island, Blueno saved his injured comrades with his Air Door, and the group fled along the tracks before busking in St. Poplar to fund Lucci's care. During the timeskip he helped smash an Underworld scheme involving escaped Level 6 convicts and won reinstatement into CP0, later watching the Revolutionary strike on Mary Geoise and helping guard the captured Vivi within Pangaea Castle.
