C2-N2 is a starship droid for all the Galactic Republic classes including the Jedi Knight, the Jedi Consular, the Smuggler and the Trooper. C2-N2 is an auxiliary companion primarily used for crafting purposes, though he can be used in the field in any role. While being used in the field, he will use his fists to fight in battle. He is found on the player's ship at all times other-wise and will say various phrases as you pass him aboard.
