Getter Robo: Armageddon or Shin Getter Robo: The Last Day; Change!! Or Getter Robo: The Final Days of the World; or just Shin Getter Robo , is a Super Robot OVA from 90'S it's animation holds up pretty well , the characters are great , Ryoma is the best part , and of course the first episodes were done by a different director than the other episodes , the plot is the invaders alien race plan to control earth but the Getter Gang won't let them , the show is a blast from episode one to the last episode, pros the animation and characters, cons the plot is way different from episode 4 onwards, and it's never explained stuff like at all
