Vyro-Ingo

The Vyro-Ingo are insane yet sapient crustaceanoids that were brought up on the planet Izanagi V in the Kessari Quadrant, although this is likely not their homeplanet. Their ancestors were non-sapient until their upliftal by the Precursors, during the process though they were split into two species - the Vyro-Ingo and the VUX, causing them to "lose" DNA. This caused the Vyro-Ingo to be left with a sense of genetic inferiority that lead to a form of insanity where they habitually insult other species, presumably out of jealousy. Eventually however the captain and leader of the New League of Sentient Races successfully united the two species on one planet, allowing them to fuse into one species again over time; presumably through copulation aided with technology.
