Mazinger Z is my favorite robot. I've collected the entire Soul of Chogokin line diecast robots which includes any member of the Mazinger family including Great Mazinger, Getter Robo, Grendaizer, etc.
However, i didn't get the quiapo dvds as most of subtitles originate from China with their atrocious grammer and spelling. Kaka walang gana panoodin.
