Striker

The Striker is a raft used by Portgas D. Ace.

Appearance
The Striker is a one-man, water-proof raft. It is a yellow craft, shaped like a half-crescent, with an engine in the back, and two paddle-wheels on the side, all linked to the main seat in the middle of the craft. There is also a single small sail at the back.

Abilities
The Striker is powered by Ace's Mera Mera no Mi fire powers, from the front seat that is linked to the engines on the sides and back of the craft. The ship has also been able to dive underwater, with Ace jumping over obstacles, so it is most likely to have been coated. Ace seemed to be comfortable and confident in it.

History
The Striker was first shown during Ace's fight with Baroque Works Billions' ships. As Ace used his "Fire Fist" to annihilate the fleet, the Striker dove under the water, and Ace jumped over the wreckage. Then as the craft reemerged, Ace got back on and left. It's unknown what happened to it after Ace's loss against Blackbeard.

Trivia

 * Striker is the only vessel powered by a Devil Fruit ability to be rendered useless as after Ace's death the Mera Mera no Mi is currently not in use.
