Resident Alien Season 4: Confirmation, Move To USA & Everything We Know (2025)

Across its three seasons thus far, Resident Alien has delivered the laughs while also raising the stakes with each passing episode, and now season 4 is coming soon. Debuting in 2021 and based on the eponymous comics by Peter Hogan and Steve Parkhouse, Resident Alien follows an alien (Allen Tudyk) who is sent to destroy Earth. However, upon assuming the identity of a physician, he begins to grapple with the moral dilemma of wiping out a species he grows to care for.

Scoring high marks from critics since the debut season, Resident Alien is largely carried by the stellar performance of Allan Tudyk who excels at the sort of character work required by such an odd premise. Likewise, the humorous writing of the series is both raunchy and clever, and Harry's decision to change his mind about destroying Earth is earned instead of assumed. With the show so able to change its basic premise on a dime, the future of Resident Alien is brighter than ever, and season 4 will be airing on a new network as well.

Resident Alien Season 4 Latest News

Writing Begins On Season 4

A few months after season 4 was renewed (with the move to USA), the latest news confirms that work has begun on Resident Alien's next season. Though the future of the sci-fi comedy seemed grim, writer Aaron Wiener has offered a hopeful update by revealing that writing has begun on season 4. Though he didn't reveal any specifics about the upcoming episodes, Weiner shared the news on his X (formerly Twitter) account and thanked viewers for supporting the show while urging newcomers to join the fun.

Season 4 Is Coming Soon

After a lengthy period of uncertainty regarding the show, the fate of Resident Alien was finally decided in June 2024 when it was renewed for its fourth season. The renewal order also came with a move to the Syfy channel's sister network, USA, a move that will also see the show face drastic budget cuts.

A Change Of Network To Bolster Ratings

Almost as soon as season 3 concluded, rumors began to swirl that Resident Alien season 4 wouldn't be airing on the Syfy Channel. Finally, it was decided in June 2024 that the show would be renewed, but that it would now air on the USA network in an attempt to bolster dipping ratings. Though USA offers the show more audience exposure, the move will also be accompanied by a large budget cut in order to keep the show financially feasible. It's unclear at this juncture what the budget cuts will mean for the production of season 4.

Resident Alien Season 4 Cast

Will Harry Return In Season 4?

Though nothing can be confirmed, it is assumed that the main cast of Resident Alien will reprise their roles in season 4. This means Alan Tudyk will once again be leading the show as the extraterrestrial who pretends to be Harry Vanderspeigle, and Sara Tomko will be back as Patience local Asta Twelvetrees. It's unclear if Linda Hamilton will continue to play a prominent role as General McCallister, but she will likely return as well.

The rest of the returning cast is expected to include:

Actor	Resident Alien Role
Alan Tudyk	Harry Vanderspeigle
Sara Tomko	Asta Twelvetrees
Alice Wetterlund	D'Arcy Bloom
Corey Reynolds	Sheriff Thompson
Linda Hamilton	General McCallister
Elizabeth Bowen	Deputy Baker
Levi Fiehler	Mayor Hawthorne
Meredith Garretson	Kate Hawthorne
Judah Prehn	Max
Gary Farmer	Dan Twelvetrees
Enver Gjokaj	Joseph Rainer
Clancy Brown	Mantid

Resident Alien Season 4 Story

Will Harry Escape The Greys?

The ending of Resident Alien season 3 was perhaps the most shocking so far, as Harry's plot to stop the Grey invasion landed him in captivity. After discovering that the moon was actually just a Grey spaceship, Harry attempted to thwart their plans to transform Earth's atmosphere but was captured in the process. Now, season 4 could see the fake Harry (Mantid in disguise) wreaking havoc as the real Harry's allies try to find a way to rescue him from the clutches of the evil Greys.

Furthermore, Mike's discovery that aliens are real will undoubtedly transform his character after years of suspicion, and he might come around to helping Harry's cause. Either way, Resident Alien season 4 will start with Harry in a precarious position, and the destruction of Earth seems more imminent than ever before.
