I watched some Robot Girls Z today. Basically a story about some cute girls who can "transform" into powered up girls based on Toei (same animation studio who animated G1) robots, such as Mazinger Z (aka Tranzor Z), Great Mazinger, Grendizer, Kotetsu Zeeg, Getter Robo, Gaiking etc. etc. Fans of 70s Super Robot series should get a kick out of the loads of fan references (and shameless silliness)
