Starbound Pariah

A mecha/science fiction multicross harem adventure, with a heavy focus on character development and progression!

An unassuming man named Lewis McAllister is snatched from his regular life in the present and sent tumbling a thousand years into the future by a freak accident. After wading across a desert planet and locating an abandoned ship, he discovers he is now the Captain of the most advanced spacecraft in the Universe, under the watchful eye of an artificial intelligence system named RHEA. Utilising a time-space displacement core, they begin to build a crew of like-minded spacefarers from various 'fictional' franchises.

There's just one problem - RHEA has become increasingly unstable through her isolation, and now she intends to reward her rescuer by turning them into his personal harem.
