Resident Alien Season 4 Premieres with Alien Power Loss, Expands Key Character Conflicts

The fourth season of Resident Alien continues to explore the chaos caused by shapeshifting aliens, with Alan Tudyk playing two versions of Dr. Harry Vanderspeigle, including the shape-shifting Mantid, while also directing the season premiere. A significant plot development is that Harry returns to Earth after a month-long captivity but has lost his alien powers, complicating his ability to confront threats, including the Greys and his upcoming reunion with his alien father, who aims to push him toward evil. The series, which gained a larger audience after moving to Netflix in early 2024, follows Harry's struggle to assimilate into human life while protecting the town of Patience, Colorado, and dealing with escalating alien threats. Season 4 also introduces new dangers as the Mantid impersonates Harry and holds key characters hostage, leading to tense confrontations. The show airs Fridays at 10 p.m. ET/PT on Syfy and USA Network, with episodes available the next day on Peacock, broadening viewing options. Fans can expect continued suspense as the mystery of Harry's lost powers unfolds and the true intentions of the Greys and other aliens become clearer.
