An idea I had for a Steven Universe Mecha AU, heavily borrowed from Star Driver ;p



Garnet is an avatar of the combining Mech Garnetus; she is the physical representation of the psychic connection between Ruby and Sapphire, pilots of Rubinus and Sapphirus, respectively.



They almost never uncombine, so their psychic avatar has an uncanny level of freedom. it can even project itself long distances away from her mech. This easily fooled the team’s young mechanic/pilot Steven into not figuring out that her mech is a combiner.
