A+ in all categories: originality, artwork, music, fight scenes and character development. This anime is very high on my list. It delves into the question of human evolution in outer space at an accelerated rate. Armored exo-skeleton warriors who easily destroy everything in their path, with a grudge against the earth that forgot about them, have found their world of origin and are on their way back seeking revenge. Only one of their own can stop them and it won't be easy... Originally 3 forty minute episodes, this unforgettable anime has no CG. Fighting anime fans will not be disappointed.
