The Sentai Gate was a large gate that guarded the entrance to the Sentai Fortress. It was heptagonal-shaped and lined with thick orange armor plates. The gate itself consisted of two grey doors separated vertically down the center. Throughout the First Era, it was subjected to heavy blaster fire from robot forces, most notably during the Striking Venom Attack. Though it held strong through the punishment received, the gate was severely damaged in the battle.
