Rocky Hattari

Rocky Hattari (ロッキー・ハッタリー) is a character who appeared in the Treasure Battle! and Ocean's Dream! - Oceans of Dreams. He is a newspaper reporter of a company called Blueberry Times.

Appearance
Rocky is an average height and somewhat bulky man, with short, wild blond hair. He wears a light red shirt with a black leather jacket over it, blue jeans, and sunglasses. His leather jacket has a logo on the back that says "Peace & Love". This logo is also on his guitar case.

Personality
Rocky is very confident and somewhat cocky. When he defeats someone in a challenge, he plays his guitar obnoxiously loud as an insult to the other players. He also shows no fear when challenging strong opponents, like Luffy and Smoker. Rocky does have a soft side, which he showed when imagining a great story after being defeated by Luffy.

Mr. 2 Bon Kurei
When entering the Treasure Battle challenge, Rocky needed a partner. He and Bon Kurei decide to become partners. Though they are a team, Rocky feels indifferent toward Bon Kurei. It is seen that the feelings are mutual, since Bon Kurei claims to be both a man and woman and says he is a "team" by himself.

Monkey D. Luffy
Rocky and Luffy seem to have a mutual respect for each other, as Luffy believed they were in a friendly competition and Rocky was in awe of his abilities at the end of the game.

Nico Robin
Rocky sees Robin as a rival. When Crocodile and Robin are defeated by Luffy and Vivi, Rocky appears to capture the story and congratulate the winners. Robin teases him, asking if they will be interviewed. Rocky then becomes enraged, as his confidence doesn't allow for him to be mocked.

Abilities and Powers
Rocky appears to be a skilled musician and guitarist. It can also be assumed that he is a skilled reporter, as he is willing to challenge pirates to Treasure Battles for a news story.

Weapons
Besides using his guitar to play music, Rocky uses it as well as the guitar case like axes and appears to be quite proficient in fighting with them.

He also uses large speakers when playing to distract his enemies and attack them with blasts of sound.

Treasure Battle!
He first appears in Treasure Battle challenging the Straw Hat Pirates to a variety games, for a chance to win Treasure. In the story mode, Rocky partners up with Mr.2, since he can't participate in a Treasure Battle when not in a team. He and Bon Kurei fight against multiple enemies during the challenge. After being defeated by Luffy and Vivi like Crocodile and all the other competitors, he decides to write an amazing story about his experiences and the battles that took place.

Ocean's Dream! - Oceans of Dreams
Rocky also appears in the game, Ocean's Dream. His role, however, is unknown.
