A Hybrid is a warrior/fixer that travels planets who sacrifices personal comfort for a reward further down the road.

They must love the job. They are never native to the planet they reside on. It is very hard to explain.

They are extraterrestrial in the sense, they feel alien to the planet very soon after birth, and are often outcast.

People often view them as "not normal".

I'll take "not normal" over normal.
Normal is insanity.
