The Zaku I is a fictional mobile suit from the Mobile Suit Gundam franchise, created by Yoshiyuki Tomino. It is one of the earliest models developed by the Principality of Zeon during the One Year War. The Zaku I is characterized by its distinctive green color and humanoid design, featuring a mono-eye sensor for targeting. This mobile suit is less advanced than its successor, the Zaku II, but it played a significant role in the early battles of the war. Equipped with a 120mm machine gun and a heat hawk, the Zaku I was designed for versatility and mobility on the battlefield.
