The Whitebeard Pirates were once in the past one of the most grounded privateer groups on the planet, as their late skipper, Whitebeard, was the main privateer to have been a counterpart for the Pirate King, Gol D. Roger, in a battle.
Whitebeard's team was sectioned into Divisions, rather than all under their Captain's immediate order.
Division Commander #01: Marco the Phoenix
Division Commander #02: Kozuki Oden (previous)/Fire Fist Portgas D. Expert (perished)
Division Commander #03: Diamond Jozu
Division Commander #04: Thatch (perished)
Division Commander #05: Flower Sword Vista
Division Commander #06: Blamenco
Division Commander #07: Rakuyo
Division Commander #08: Namur
Division Commander #09: Blenheim
Division Commander #10: Curiel
Division Commander #11: Kingdew
Division Commander #12: Haruta
Division Commander #13: Water Buffalo Atmos
Division Commander #14: Speed Jiru
Division Commander #15: Fossa
Division Commander #16: Izo
So Kozuki Oden was the second Division Commander, before leaving the team and joining the Roger Pirates.
It has been expressed by Oda that all the Whitebeard Commanders, regardless of which Division they are driving, are generally equivalent in rank and the division number doesn't show their quality. Be that as it may, outside Ace, who was Luffy's sibling and along these lines normally got a great deal of presentation, three of the Commanders, Marco, Jozu, and Vista, have been given undeniably more love and center than the others.
Following the passings of Whitebeard and Ace, the rest of the individuals from the group drew in the Blackbeard Pirates in the Payback War, which finished with the Blackbeard Pirates mercilessly crushing them, trailed by vanquishing their previous domains, with their chief of naval operations usurping Whitebeard's situation in the Yonko. Therefore, the team has lost the vast majority of its capacity and impact.
