A Zangyack fleet first attacked Earth in what came to be known as the Great Legend War when they were countered by the first 34 Super Sentai. Early on, there was a massive battle where over 100 robots/giants fought against the Zangyack fleet. Many of the robots were destroyed or killed during this battle. While the Sentai teams fought the ground forces, hundreds of Sugormin and Gormin, the Zangyack fleet fired upon them. Tsuyoshi Kaijo gave the order for all of the groups to combine their powers into one attack. The resulting blast wiped out the entire Zangyack invasion fleet. Consequently, all of the Super Sentai warriors lost their powers.
Eventually, a second invasion of Earth begun, overseen by the Emperor's son Warz GillWarz Gill from his chariot-like flagship Gigant Horse, stationed between Earth and its moon, with an armada at his command. However, their efforts were hindered by the 35th Sentai team, the Kaizoku Sentai Gokaiger, until eventually, Warz Gill was killed. The emperor, Ackdos Gill, took charge of the invasion and had the Zangyack fleet above Earth destroyed and replaced with his imperial ships. After Damaras' death, decided to bring in reinforcements from across the universe to conquer Earth and defeat the Gokaigers once and for all. Shortly after the Gokaigers unlocked the Greatest Treasure in the Universe, a Zangyack armada far greater than the one in the Great Legend War appeared, the Imperial fleet led by the Gigant Horse being backed up by possibly millions of battleships.
