A Pokemon with the ability to use Gravity would be useful if you would like to make the story realistically detailed considering how little time it would take for the human body to atrophy from a zero G environment. If the ship produces artificial gravity (or if Pokemon are determined to be immune to space atrophy), it's still useful for spacewalks, or exploring moons/ asteroids with very little gravity.
Personally I would write it with two trainers
romance and drama are my modus operandi along with Pokemon they can understand through some nifty space age tech. Then again you could also make the crew all Pokemon and go for a Mystery Dungeon setting.
