Alright...so Here's three ideas for my character, who is the captain of this crew.
1. Paramecia Type Fruit, Gear Gear No Mi. Allows one to create gears on their body and other objects, and make them spin/work appropriately.
Pirate name: Clockwork Pirates.
Flag: A smiley design, only the outer portion is gear shaped instead0, and the eyes have steam-punk goggles drawn over them.
2. Logia Type Fruit, Kaze Kaze No Mi. Allows one to control, become, and generate Air/Wind.
Pirate name: Hurricane Pirates.
Flag: A skull and Crossbones design. The Skull has an Eyepatch (Naturally) and is surrounded by a Tornado/Hurricane.
3. Mythic Zoan Fruit, Inu Inu No Mi: Model Raiju.
Allows one to take on the form of a Raiju, or a Lightning Wolf. The Wolf is quite large, about the size of a small dingy/boat. The Fruit also gives it's owner the power to control/become electricity, as well as transform into a ball of electricity to travel while in Half-zoan form. It also allows one to fly in their full wolf form. And of course, they get all the powers of a normal Wolf as well..enhanced hearing, Smell, sight, etc, etc.
Pirate Name: Tempest Pirates.
Flag: A skull and Cross-bones design, where the Skull is shaped like a Wolf-Skull, and the Crossbones are replaced by lightning bolts.
What do you guys think?
