AppearanceMr. 5 is a rather tall, black-haired man. He wears a brown trenchcoat with a pink cravat and a pair of sunglasses, regardless of the time of day. Like the other officers, his number is shown both on his clothing and his body. He has a "5" on his coat; this number is also tattooed on his chest and right shoulder.
PersonalityLike most of the Baroque Works agents, he is extremely confident and believes that friendship is a sign of weakness. Mr. 3, upon hearing about his defeat at Whiskey Peak, describes Mr. 5 as "an over-ambitious fool who didn't realize his limits and misused his Devil Fruit powers".
AbilitiesMr. 5 has the power of the destructive Bomu Bomu no Mi (ボムボムの実, Bomb Bomb Fruit, called Boom Boom Fruit in the English manga), which allows him to turn any part of his body into a bomb without harming himself and it renders all explosive based attacks useless against him. He can make any part of his body, even his entire body, explode, but he mainly uses boogers from his nose.
WeaponsThe gun Mr. 5 uses for his Breeze Breath Bomb attack is a Flintlock .44 caliber 6 shot revolver, a new model from the South Blue complete with rapid-fire capabilities.
HistoryMr. 5 and Miss Valentine first meet the Straw Hat Pirates at Whiskey Peak during the Whiskey Peak arc, then later fight them at Little Garden with Mr. 3 and Miss Goldenweek during the Little Garden Arc where he is knocked out by Zoro's Yaki Oni Giri attack.
* Note: In the 4Kids English dub, because Little Garden arc was cut out, he appears only at Whiskey Peak and is defeated there and then.
He, along with Miss Valentine and Miss Goldenweek, has reappeared in the series in a chapter cover mini story where the three fly away from Little Garden to visit their captured Baroque Agents only to end up on an island resort swarming with marines. They manage to release most of the agents and he helps out at the new Spiders Cafe.
