This is locaste the Kalcinian. He came to Earth along with the Stafu Sniper and several other Kalcinians after they left Rhenia to run away while some heat on them cooled down, and also as a tax break. However, their ship's emotional guidance chip was damaged in the landing now they are stuck here!
Locaste (the E is silent, accent on the O) here cut off the wrong head in a bar, and now has nowhere to call home and is stuck on a planet full of strange anthropomorphic creatures who may or may not accept him.
