Resident Alien Season 4 OTT Release Date: When and where to watch Alan Tudyk and Sara Tomko¡¯s mystery series

Resident Alien Season 4 OTT Release Date: After months of waiting and plenty of fan speculation, Resident Alien is finally returning for its fourth season, and things are getting weirder, darker, and funnier than ever. If you¡¯ve been following the story of the alien-turned-doctor Harry Vanderspeigle and his bizarre adventures in the small Colorado town of Patience, get ready to buckle up.

The fourth chapter kicks off on Friday, June 6, 2025, airing at 11 PM ET/PT on Syfy and USA Network, with new episodes landing on Peacock a week later. Indian viewers can stream Resident Alien Season 4 on JioHotstar starting June 7.

Previously, in patience...

Season 3 left viewers hanging on multiple fronts. Harry, played with brilliant awkwardness and charm by Alan Tudyk, was trying to figure out his role on Earth. He had already aborted his original mission to destroy humanity (thankfully), but that didn¡¯t mean Earth was safe. By the finale, things were getting truly alien.

We met Harry's half-alien daughter, Bridget, and watched as they both were abducted by the Greys and taken to their Moonbase. Meanwhile, back on Earth, things were unravelling. A sinister new alien species, the Mantids, made their presence known, and one of them had shapeshifted into a doppelg?nger of Harry.

Yes, there were now two Harrys in Patience, and the wrong one was walking around pretending to be him. Asta, Harry¡¯s closest human ally (Sara Tomko), had her own emotional rollercoaster. Her relationship with her father, Dan, and her own sense of identity were tugging at her deeply. D¡¯Arcy, still recovering from physical and emotional wounds, was caught in her own web of regret and vulnerability.

Meanwhile, Sheriff Mike and Deputy Liv continued being the unlikely, low-key MVPs of the town¡¯s law enforcement even as more strange things began happening around them.

What¡¯s coming in Season 4?

Resident Alien Season 4 doesn¡¯t waste time. It opens right where Season 3 ended, Harry and Bridget are prisoners on the Greys¡¯ Moonbase. They¡¯re being studied, interrogated, and ultimately forced to reckon with the larger alien threat looming over Earth. Harry manages to escape, of course, he¡¯s too clever not to, but Earth has changed in his absence.

Back in Patience, the Mantid, posing as Harry, has been causing havoc. This new enemy is smarter, deadlier, and utterly devoid of Harry¡¯s fumbling humanity. As the real Harry returns, he¡¯s faced with an impossible task: convince the town that he¡¯s the real alien doctor and stop the Mantid before it does something irreversible.

At the heart of the season, though, is still Harry¡¯s evolution. He¡¯s not the alien assassin he once was. He¡¯s someone, something, that cares. And that empathy will be tested like never before.

Meet the cast and characters

Alan Tudyk remains the heart and soul of the show alongside Sara Tomko, as Asta, who grounds the show emotionally. The returning cast includes Alice Wetterlund as the resilient D¡¯Arcy, Corey Reynolds as Sheriff Mike, Elizabeth Bowen as the ever-curious Deputy Liv, Levi Fiehler as Mayor Ben, and Judah Prehn as the ever-sceptical Max. Stephen Root, known for roles in Barry and Office Space, is joining the mix this season as Harry¡¯s alien ¡°father¡±.
