If I were to start a pirate adventure my crew would be called the Blue Moon crew, riding on the clouds when the moon is full, plundering any in our sights. We would hail from Skypiea. Our flying ship would sail above the ocean using dial power allowing us to pass through the calm belt with ease and bypass the grand line to find the one piece.
I would get Asakura Yoh from shaman king as my swordsman along with Amidamaru his trusty spirit companion.
I would have Ginta from MAR as my first mate along with Babbo his taking weapon.
I would have Yoda from Star Wars as a Historian for the group.
I would have Master Chief from Halo as my gun expert.
I would have Steve from Mine Craft as my shipwright, because he can build about anything and with his skill with a sword and bow and arrows make him a force to be reckoned with.
I would get Red foot Zeff as my cook, before he met Sanji.
I would get the Eternal Dragon from Dragon Ball Z as a pet/doctor when I need him.
I would have Nami as my navigator.
