The One Piece Battle

The One Piece Battle, also known as One Piece VS Figure Gashapon is a 5-piece Capsule set issued in Japan. Each wave featured 5 figures (assembly required) in a capsule ball. The character were captured in mid-attack and stood on a stand in a tear-drop shape. The figures could be placed in front of each other, with the tear drop shapes sliding together to form an impression of two characters fighting each other.

Interestingly enough, the alternative name One Piece VS comes from the capital VS letters that could be seen behind the Japanese title in promotional advertisements for wave 1. But actually, it was just some marketing playwords and the VS word is not part of this series name.
