Kaku

Kaku (カク, Kaku) is first seen as one of the five foremen of Galley-La Company's Dock One and specializes in mechanics diagnostics and housecalls. It was Kaku that inspected the Going Merry and informed the Straw Hats that it was irreparable.

Personality
Surprisingly however he is very honest even to his enemies and even more so then Fukurou, though doesn't seem to take insults well as no sooner then his giraffe/human form was mocked he sliced the Tower of Justice in half.

After being revealed as one of the Water 7 CP9 agents, Kaku's personality becomes cold and rather emotionless in contrast to his character on Water 7 where he was mainly seen laughing and smiling. Despite this, he often taunts his opponents during battle, ate a Devil Fruit for the fun of it, and exclaimed "This is fun!" during his life-and-death battle with Zoro. He also seems to place a chance to fight over easy accomplishment of a mission; when Zoro and Sogeking were cuffed together he wished to help them, so he wouldn't be forced to share his target with Jyabura. When neither agent had the key, both agreed that the prey was up for grabs.

Kaku showed great sportsmanship after his defeat where he laughed at Zoro's comment of working in a zoo, and handing over his key without Zoro having to say a word, leading one to believe that he is not as cold-hearted or evil as he appears.

Powers and Abilities
He is able to move incredibly fast and leap from buildings from amazing heights and distances without a scratch. A lot of the characters mistake him for Usopp since he too has a long nose. During his disguise as a shipwright, Kaku uses a variety of pavers/chisels as projectile weapons (used against Luffy in Dock 1.) After his true identity is revealed, he clashed with Zoro using two giant chisels as swords in Iceburg's room.

Kaku's expertise seems to be in rankyaku, due to his many variations of it. He is also the most proficient swordsman of CP9, being a user of the Yontou-Ryuu Attacks (四刀流, Four Swords Style) by the use of two swords and both legs (with rankyaku).Kaku's fruit is Ushi Ushi no Mi Model: Giraffe (ウシウシの実 モデル麒麟(ジラフ) Cow Cow Fruit, Model: Giraffe), which allows him to transform into a giraffe-human hybrid and a full giraffe.

History
Kaku was also the one responsible for sending the Going Merry into the midst of the Aqua Laguna and to its apparent demise.

At Enies Lobby, he and Kalifa were given Devil Fruits by Spandam and, under the urging of Lucci, ate them. Although he was initially going to face off with Zoro, he ended up causing the floor to cave in by transforming into his full giraffe form instead of his half-giraffe form. The two fell into the room where Sogeking and Jyabura were fighting, and were involved in that fight as well. The individual fights went on, until Kaku was defeated by Zoro.

CP9's Personal Report
He appears on the third cover in the report, sitting, and apparently severely injured, having been carried by Jyabura along the Sea Train tracks. He has currently arrived at St. Poplar and is shown pretending to be a "giraffe slide" while in his full giraffe form for children to ride, in an effort to help CP9 raise money for Rob Lucci's medical bills. He is later seen at a café with Fukurou, Blueno, and Jyabura waiting for Kalifa and Kumadori to return with the shopping, he along with Fukurou is laughing at Jyabura.

Translation and Dub Issues
Kaku's name most likely comes from the Japanese word kaku (角, angle), a reference to his rectangular nose.

Trivia

 * He has a giraffe theme, due to his devil fruit.
 * Kaku's birthday was revealed in a Volume 43 SBS to be August 7. This is because in Japanese, 8 can be pronounced as ha, and 7 can be pronounced as na. Put together, these make hana, the Japanese word for nose., in reference to his long, rectangular nose.
 * He is 23 years old, although he speaks as if he were much older, as he adds the suffix "-ja" to most of his sentences. "-ja" is commonly used amongst old men.
 * When invading the Iceburg's mansion he was wearing the skull mask.
 * Kaku ranked 9th place in the most recent popularity contest, making him the most popular CP9 member, as well as the most popular villain in general and the second most popular character outside the Straw Hat crew (However, in the last fan poll, Mr. 2 Bon Clay had the same spot as Kaku does now).
