Loco is the strongest Rook and one of the first Chess Pieces introduced. Loco's name means a patron of healers in the religion of Voodoo, a reference to her ÄRM Straw Doll (Spikes and Hammer). Loco was born 32 years before the main part of the series. At age 26, Loco, at that point a Pawn, the lowest Chess Piece rank, was given the order to participate in the attacking of a, unknown, town. While fighting, Loco's only ÄRM the Weapon ÄRM Ring Dagger, was broken, leaving Loco defenseless. While stumbling throughout the battling village, Loco crossed paths with a midget-like cloaked figure carrying a large suitcase. The cloaked person asked Loco if she wanted strength, to which she answered that she only wanted power to fight with. The cloaked person then gave Loco the suitcase, telling her it was full of seven Darkness ÄRMs, the cost of using being reversed aging, and the mysterious figure died from the ARM's effects. Using the Darkness ÄRMs, Loco eventually increased in the ranking system to the strongest of the Rooks. The Darkness ÄRMs affects had damaged her, however, as her body had been transformed into a young child's by the series' beginning.
Elizabeth resembles a giant white duck or a giant penguin and is Katsura's companion. Elizabeth was a present from Tatsuma Sakamoto, who presumably picked it up on his travels around space. Although many people consider Elizabeth to be insane and extraneous, Katsura has named the ambiguous avian "Elizabeth" and dotes on it. Once in episode 18 Shinpachi purchased a doll named as Space Alien Stefan (宇宙怪�ステファン) to which looks perfectly similar to Elizabeth. Elizabeth is something of a painter, and is surprisingly dexterous. Also, Elizabeth resorts to using signboards to "communicate," as well as an occasional means of attack. Elizabeth is also a skilled fighter, able to use signboards to fight off swordsmen. Although the true identity of Elizabeth is uncertain, it appears to be a man wearing a duck costume. In its first appearance, hairy legs are seen underneath her sheet and the body of a humanoid with glowing eyes is revealed as her mouth is opened just as it fell during another battle between Gintoki and Katsura. Although Katsura seems shocked at what she really is, she has subsequently remained by his side. Episode 50 implies that the person inside Elizabeth is most likely the director (Gintoki was interrupted before he can finish being cut off at "Kanto-" ("Direc-"). Most of the characters seem to ignore this, or at least do not give it much thought, given at the episode was completely filler. Moreover, the next time the inside of Elizabeth is shown, it reverts to the glowing eyes. When Shinpachi boards Takasugi's ship in order to rescue Kagura, a bazooka is seen coming out of Elizabeth's mouth when she blasts the ship to distract everyone from Shinpachi. Because of this, Shinpachi refers to her as Elizabeth-senpai. Elizabeth's birthday is September 7. "Her" height is 180 centimeters, and "she" weighs 123 kilograms. (Source: Wikipedia)
