G1 Headcannon: When very bored at base and doesn't have shit to do Rapidbrawn {as an adult} will sneak out of base and go to a race track and race for fun and like his sire will brag that he is better racer than the humans, he even will at times race againt Dragstrip who will also drag Embertrail to watch and will brag it to him saying he's better than his dad while Drag tries to do it back while Embertrail watches nervously but Dragstrip is proud of his son while thinking it when Rapid wins some of the races.
Dragstrip: {;-; I'm so proud. They grow up so fast!}
Embertrail: *anime sweat drop* one of these days you two are going to be the death of me
