Here are the list of playable species so far.
CLASS: Imperial Agent. Very tall humanoid race with blue skin, red eyes, and black hair. The Chiss live on the ice-locked planet Csilla. Their social structure is highly regimented and above all, the Chiss value conformity and strict behavior codes.
CLASS: Jedi Knight, Jedi Consular. The Miraluka are very attuned to the Force, making them especially suited to become Jedi Knights. They have evolved beyond the need for normal sight and usually cover their vestigial eye sockets with decorative blindfold-like coverings.
CLASS: Jedi Consular. Known for their natural agility and unusual insight, the Mirialans are quick on the battlefield and discerning in diplomacy. They are distinct in appearance because of the geometric tattoos on their faces and hands. These tattoos denote mastery of skills or personal achievements.
CLASS: Bounty Hunter. These bald-headed, white-skinned humanoids are a violent race, skilled in gladiatorial combat. Rattataki were featured in the animated series Clone Wars.
CLASS: Sith Warrior. These red-skinned humanoids are of the original Sith race from the planet Korriban. The driving force of the Sith Purebloods is the hatred passed on from generation to generation, making these descendants of Naga Sadow and Marka Ragnos truly intimidating on the battlefield.
CLASS: Jedi Consular, Smuggler. Humanoid species from the planet Ryloth. Twi’leks are instantly recognizable by the prehensile double tentacles, or “brain tales.” Their possible skin colors are extremely diverse — blues, greens, reds, browns, white.
CLASS: Sith Inquisitor, Trooper. Marked by their horns and facial tattoos, the Zabrak are a fierce and combative people. They defeat their enemies with their aggressive fighting skills and Force use.
