I'm writing to you from Germany, so sorry for bad grammar. Well a long time ago, 1996/97/98, I saw an anime on cartoon network. Now it was about robots (what else) that would fight and some kids would control the robot's. Now every now and then this mysterious robot came rolled in (literally rolled) and saved the day! Now I don't know much more so if one of you know what I mean than please tell me.
Thanks in advance!
