The Universal Annihilation Army Warstar are the first set of antagonists in 34th Super Sentai Series Tensou Sentai Goseiger. Based on the Universal Mothership Indevader, the insect-themed members of Warstar travel to various worlds to strip the planets of their natural resources. Arriving to Earth, Warstar is joined by Brajira under the guise of Buredoran of the Comet, used by him to destroy Heaven's Tower in a preemptive strike to ensure the Gosei Angels do not interfere.
Though Brajira intended to kill off Warstar's members once they served his needs, the presence of five Gosei Angels remaining on Earth delayed that intent as Warstar's members die fighting the Goseigers with the Indevader destroyed. Eventually, Warstar is defeated when its new leader dies fighting Wonder Gosei Great.
