Change!! Getter Robo: Sekai Saigo no Hi, Shin Mazinger Shougeki! Z-hen Recommendations
Getter and Mazinger, two of the ultimates in the Super Robot Genre. If you want ridiculously manly characters, insane action, kickass robots and ridiculous amounts of awesome, both deliver. Oh good lord do they ever deliver.
Both are remakes/alternate versions of 70s anime about cool people with cool robots doing cool things. The director of Shin Mazinger also directed part of Getter Robo Armageddon.
