The 1st appearance of "rappies" was in Phantasy Star 3 and are called Chirper, Warbler, and Squaker as animals and Chirpbot, Warblot, and Squakbot as robot enemies. It was in Phantasy Star 4 that they were called rappies with the 3 types being Rappy, Blue Rappy, and King Rappy. This is where they developed the trait of running from battle as they are injured.
