Unidentified Sentient Race 2 is an unnamed race of large ape-like humanoid. They are apparently discriminated against by the rest of the Galactic Federation, which, according to a captured Space Pirate, dubbed P-1, is due to them being primitive compared to most other humanoids. P-1 states that the Chozo had recommended the species to the Federation.
