Andromeda:
I wouldn't do Tyr. I liked him at first but he got to megalomania for my tastes.
I was thinking Dylan, Rommie, and possibly the Andromeda Ascendant itself. I was also considering them to be taken before they even met Tyr, Beka, etc.

Transformers:
I was thinking an original character that is a spaceship that could use a tiny robot (human size) for it's avatar on the station. The tiny robot of course was not built for such a purpose but retrofitted for that or might use a generic android from the Andromeda with Rommie's help.

Thundercats:
At least the reboot season definitely had advanced tech but it wasn't really used much except for their tank thing.
Not sure if original or canon chars.

He-Man/She-Ra:
Had advanced tech that was somehow never scene. They were able to convert humans into cyborgs.
Not sure if original or canon chars.
