Eins

Batman (バットマﾝ) Eins (エイﾝス) is the former First Mate of the Rackham Pirates, serving under the Yonko with a bounty of 1,045,000,000. Following his crew's defeat at the hands of Berry and the Little Miss Pirates, he fled back into Paradise and made a deal with the World Government: he would be their test project for the emerging Pacifisa project in exchange for a position as a Shichibukai. He would become PX-0 (PX-0), appearing frequently during events in Proud Line.

Finding himself increasingly drawn into the incidents caused by the Pride Pirates, Eins decided it was fate and betrayed the Government during the Battle on Upper Yard, siding instead with Pounce D. Luk and God's Army. In the aftermath, he was was instrumental in helping the young pirate receive his crew's message on Tone Dial, as well as delivering his response and helping him escape the captivity of the Bandit's Summit. Afterwards, he would break out fellow Pacifista prototyps Corona, Monte, and Fio before vanishing, abandoning his position for good.

He currently resides somewhere in the New World, living with his fellows and planning his next move.
