Eriedrone oversaw Jark Matter's invasion and subjugation of the planet Crotus. However, his forces failed to prevent the initial three Kyurangers from helping many civilians escape. As Eriedrone contacted Don Armage to inform him of the invasion's success, the Shogun blasted Eriedrone and ordered him to eliminate the insurgents.
