Dalmatian

Vice-Admiral Dalmatian (ダルメシアン中将) is one of the many Marine Vice Admirals to have participated in the Battle of Marineford.

Appearance
With his Devil Fruit powers active, Dalmatian takes the form of a muscular, bipedal dalmatian-human hybrid. The top part of his head, along with his arms and legs, are that of a dalmatian. He also has a tail. However, the bottom half of his face is human, and has a blonde-white beard. He has yet to be seen in his default human form.

Like all other Vice Admirals, he wears a double breasted suit, dress shirt and tie, with a Marine jacket draped loosely over his shoulders like a cape.

Devil Fruit
Dalmatian has eaten an as-of-yet unnamed Zoan-class Devil Fruit that allows him to transform into a dalmatian. Using this, he can increase his fighting prowess and physical strength greatly, and, combined with his Rokushiki style, favors his status as a martial artist greatly.

Rokushiki
Dalmatian has access to the Rokushiki martial arts style, and he has demonstrated the techniques Soru and Shigan, allowing him to move at incredible speed and pierce his opponents with his finger, respectively. The powers of his physical techniques are further enhanced by his Devil Fruit transformation. His Shigan has been even enhanced by the sharp nail point added to his finger, allowing him to pierce Monkey D. Luffy's rubbery body, just as Rob Lucci did.

Haki
It was stated that all Vice Admirals possess Haki, so Dalmatian can also use the ability. However, he has not yet been shown using it.

Battle of Marineford
When the execution of Portgas D. Ace was announcd, Dalmatian, along with the other Vice Admirals, to Marineford to battle against the Whitebeard Pirates and their allies After Monkey D. Luffy and the Impel Down escapees arrived, Luffy eventually made his way to the execution scaffold. Dalmatian and Momonga attacked him, with Dalmatian piercing Luffy with Shigan.

Major Battle

 * Dalmatian and Momonga vs. Monkey D. Luffy

Manga and Anime Differences
In the manga, Dalmatian has yet to be named, even in the fourth databook. His name came from the ending credits of Episode 476 instead. Also, in the same episode, he commented on Luffy being a mere rookie was the main reason he couldn't defeat the Vice Admirals.

Trivia

 * Since his name came from the anime instead of the manga/databooks, it cannot be considered canon, despite him being a canon character. However, it is possible that Oda informed Toei his name, since all of the New World Allies' names were revealed in the anime, before the fourth databook came out.
