Between May 27th and June 27th 2011, Banpresto ran a fan poll campaign, which was about choosing 5 characters among a lineup of 29: Charloss, Laboon, Johnny & Yosaku, Duval, Chouchou, Risky Brothers (zombie), Yorki, Tamanegi-Piiman-Ninjin, Jean Bart, Morgan, Cerberus, Shalulia, Pearl, Roswald, Merry, Ippon-Matsu, Sham, Cabaji, Richie, Motobaro, Disco, Fullbody (Baratie Arc), Carne, Mohji, Spoil, Peterman, Tararan, Boodle and Buchi.
The 5 chosen characters were released along with Killer and Shakuyaku in Japan on June 28, 2012.
I can only remember a couple of faces from those names.. =_="
Goes to show how many characters were developed through the years of One Piece.

Charloss's glass helmet had to be DIY-ed with 2 pieces of clear plastic half-domes.

Chouchou is super cute!
