Cola

Cola is a type of beverage in the One Piece world. It is presumably identical to real life cola, which is a sweet carbonated drink, usually with caramel coloring and containing caffeine.

People usually drink cola while watching special events or something along those lines. Sanji, for example, was complaining about the price of cola during the final event of the Davy Back Fight.

Cola is also an essential source of energy for newest Straw Hat Pirate, Franky. Franky is able to store cola in a mini-fridge he has where his stomach would normally be, and he can store up to 3 bottles (6 liters) of cola. Depending on the amount of cola he has stored, his attacks can be a lot more powerful, and they are weaker when he has less cola. The Straw Hats' new ship, the Thousand Sunny, also uses cola for attacks.
