Shin Getter Robo vs. Neo Getter Robo throws you into a war where the only language is robot violence, and it never stops to explain itself. The animation moves like a live-action fight choreographer designed it, every transformation and collision carrying weight that most modern mecha abandoned years ago. Four episodes is exactly long enough to remember why people used to build giant robots just to destroy things beautifully, then leave you wanting the rest of the war.

Years after the Reptilian Empire was defeated, the Getter Team is training on a new super robot, Neo Getter Robo. Their preparations are cut short when the Empire's revived leader launches a surprise attack, and the team has to bring in Go Ichimonji, a street fighter, to pilot Getter One. Against an enemy of overwhelming strength, the new team's best chance of winning may depend on reviving Shin Getter Robo, a lost weapon of humanity. Across four episodes, the OVA delivers science fiction action built around giant robots.
