Nestor

Nestor is an alien entity who inhabits the bodies of "hundreds of thousands" of facets across the galaxy. They all share a mind, their sensations and experiences all feeding the same entity. This state is something they find exceedingly boring, as such they travel the universe seeking excitement. Their Spaceships require 4 facets to operate, and will always carry a fifth "spare" as well. They have virtually no tolerance to pain. They seem to have a very acute sense of taste, as they can identify the exact chemical make-up of a hot-dog while taking a bite.
