Rollbar/Grind Rod could have been a coincidence of Engrish, but now with Hardbone being revealed there's no doubt about it, those brilliant Toyworld designers must still be in primary school
Well Aurora is a fairly normal name, I sorta get the feeling they meant to call Hardbone Hardskull, but got confused. At least Hardskull would make a lot more sense.
Are Toyworld Japanese? Certainly wouldn't be the first time this has happened.
