Resident Alien returns with its highly anticipated Season, premiering June, 2025, at p.m. ET/PT on both USA Network and SYFY. The new season launches with a twist: Harry Vanderspeigle (Alan Tudyk) and baby Bridget are imprisoned on the Greys’ Moonbase, while a shape-shifting alien—an evil Mantid—takes Harry’s place back on Earth.
This season, viewers can expect episodes airing weekly every Friday through August. The storyline picks up a month after the Season cliffhanger, with the real Harry and his son trapped off-planet and the impostor stirring up trouble in Patience, Colorado. Meanwhile, Sheriff Mike Thompson and the rest of the town grapple with the fallout from last season’s revelations, as reality and deception blur more than ever.
Returning cast members include Sara Tomko, Judah Prehn, and Corey Reynolds, with new faces like Stephen Root joining as Harry’s alien father Episodes will be available to stream on Peacock one week after their initial broadcast, and past seasons are now streaming on Netflix.
