Fans of the quirky sci-fi comedy Resident Alien can finally mark their calendars: Season 4 premieres on Friday, June 6, 2025, airing simultaneously on USA Network and Syfy at 11 p.m. ET/PT.

Episodes will also stream on Peacock one week after their linear debut.

This dual-network simulcast mirrors the strategy used for Chucky, ensuring broader accessibility for viewers.

What to Expect in Resident Alien Season 4

The upcoming season picks up with Harry (Alan Tudyk) and his alien-human hybrid baby, Bridget, imprisoned on the Greys’ moonbase. Meanwhile, a shapeshifting Mantid alien has stolen Harry’s identity on Earth, wreaking havoc in Patience, Colorado.

Though Harry escapes the moonbase, he returns powerless, thanks to an inhibitor implanted by the Greys, forcing him to navigate life as a “basic b—-” human.

Key subplots include:

Asta (Sara Tomko) and D’arcy (Alice Wetterlund) struggle to hide secrets from Mayor Ben (Levi Fiehler) and Kate (Meredith Garretson), who grow increasingly suspicious of the town’s bizarre events.

Sheriff Mike (Corey Reynolds) and Deputy Liv (Elizabeth Bowen) are investigating mysterious deaths linked to non-human forces.

A potential showdown between Harry and the Mantid, complicated by Harry’s newfound vulnerability.

New Faces and Returning Favorites

Alan Tudyk not only stars but also makes his TV directorial debut with the season’s first two episodes.

The core cast returns, including Sara Tomko, Alice Wetterlund, and Corey Reynolds, alongside recurring stars like Linda Hamilton (General McCallister) and Edi Patterson (Blue Avian Heather).

New guest stars join the chaos:

Jewel Staite (Firefly) as Jules Gardner, an FBI agent and former classmate of Asta’s group, investigating Patience’s grisly murders.

Stephen Root (Barry) as Harry’s father, adding familial tension to the alien’s existential crisis.

Production Notes and Trailer
