Commissioned from @mellliow! Thanks again for this, this is exactly the father/son dynamic I wanted!
God Ginrai and Godbomber! I RP both of them, and choose to play them as their own living beings rather than needing humans to pilot them (I know this happens at the end of Masterforce too). I thought the funniest answer to where Godbomber came from was Ginrai had a cryptic pregnancy that attached to his trailer upgrade. Surprise child! It gives me a cute father/son dynamic while also exploring Ginrai needing to become more responsible as duties pile on him.
Can also be interpreted as human Ginrai giving Shuta, Cab, and Minerva a piggyback ride in their transtectors! My intention doesn't exclude that interpretation at all. Hope everyone enjoys!
