The Big Abare with the Dinosaur Robot Drill (恐竜ロボットドリルで大アバレ Kyōryū Robotto Doriru de Ō Abare) is the eighteenth episode of Kaizoku Sentai Gokaiger. Although it has elements regarding three Sentai series (Kyōryū Sentai Zyuranger, Mirai Sentai Timeranger, and Bakuryuu Sentai Abaranger), it is not an official tribute to any of these series. It reveals the origin of Gokai Silver and the debut of his mecha made from the Greater Powers of the three aforementioned series, GoZyuDrill.
