I'm not familiar with most of those titles, except Voltron. I watched some of it when I was younger. My favorite robot related anime was Mobile Suit Gundam Wing. I was addicted to the show, and it was really popular in Canada. The toy figures were really popular too. That was one of the shows where everything just clicked for me: the storyline was interesting and political, the design of the mobile suits was fantastic, and the characters were all interesting. Also, Scott McNeil voiced Duo Maxwell in the English version, and he's my favorite voice actor.
