Well Hot Rod and Shadowstrip's bios are about as boring as possible. Hot Rod joined the race to show people he's fast and Shadowstrip is just described like Dragstrip, someone who'll do anything to win.
Crasher's is a hair more interesting, but just a hair. They describe her personality as "tough, hotheaded, and stubborn" which doesn't sound much like the cackling mad-woman from GoBots. And then says she'll demolish anyone who "crosses her in the wrong way" which begs the question if there's a right way?
-ZacWilliam, also they were clearly unsure what to say about her origin since it lists her as G2 (probably copied text from Shadowstrip) and based on her character from the Comic Books.
