G.U.T.S.
3 Engineers, and their Robot
Upon reaching the Hubworld, the first of their species to make the trip, Cannon, Fritz, and Dana realized creatures from their planet were quite small and feeble compared to most intelligent life in the galaxy. To better accomodate themselves to this new ecosystem, they built G.U.T.S., an intelligent robot who also functions as a suit that can be piloted by the three.
IOTA tries to meet with the three due to their knowledge of robotic engineering, in hopes that they could help him recover some of his corrupted memory. Unfortunately, unlike his siblings, Cannon is unsympathetic to IOTA's cause and views him as a freeloader who must be destroyed. Fortunately for IOTA though, while G.U.T.S. is perfectly capable of combat himself, Cannon prefers that the siblings manually pilot him during combat situations out of pride in his own abilities. This doesn't tend to work out well for the three.
