I think a good idea to help worldbuilding is if each of us talked a little bit about the "show" that our character came from before being featured in this Super Robot Wars style game. For example, Gogekkor V would be a super robot show from the late 70s. It featured a combining robot sent to Earth by the natives of Io for them to fight the coming Jovian invasion. It had five pilots, all teenager, and I want to say they were also a band, and the show is sort of infamous for having the main robot destroyed in its last episode with the Jovian Lizards still undefeated. Originally the robot was supposed to be rebuild better than before and take the fight to Jupiter, but the budget got slashed 3/4ths of the way through with only 36 of the planned 48 episodes being produced. Episode 36 was hastily rewritten to be the finale, and to end on a more hopeful note than it originally ended with one of the lizards being swayed to the Earths side.
