[@FrozenEcstasy] So looking over the revisions thus far, I feel like you've done a good job at focusing Omega, but now that he's just a "researcher," he's left in a nebulous sort of position where he doesn't quite have a viable role on Nova Dawn. If he's simply a biologist with some light combat and magic abilities, I can't quite justify Sulk taking him onboard. This isn't the HMS Beagle after all. Regarding his status as an android, I stand by my earlier suggestion that making him a fully robotic lifeform from a robot world would be the best and most interesting solution.

So here's what I'm suggesting: fully embrace the researcher role. The idea of him being adapted into a war robot just detracts from the strength of his theme as a character. Making him a navigator again would work very will with him being a researcher, as he would be committed to researching and deciphering the Aetheric Lexicon, giving him a solid role on the ship. If you wanted to keep him as a biologist, sure, but if you were going with the robot world idea and/or this suggestion, perhaps an astronomer or cartographer would be more appropriate.
