Does anyone remember an 80s cartoon show, Japanese in origin, that featured a boy and a girl in a sort of tank like thing (the memory isn't what it used to be-maybe it was a robot), being chased around by an evil boy and girl in a spaceship? I think the bad guys had a dog. At the end of each episode, the bad guys' spaceship would always get blasted into the stars. Sorry if my description sucks, but I was very little at the time, and can only remember bits and pieces. If this rings a bell, do let me know. Thanks!
