'Resident Alien' Returning for Season 4—With One Major Change

Harry is coming back! Fans of the sci-fi show Resident Alien are ecstatic over the news that everyone's favorite milk-guzzling alien is returning for a fourth season. The show found a new audience when the first two seasons arrived on Netflix ahead of the Season 3 premiere, and the show has only picked up steam from there. Along with the hashtag #GiveUsRAS4 on social media, fans made it increasingly clear to NBCUniversal that this show needed another season.

With the new season comes change, though. Originally airing on SYFY network, the fourth season will move to USA Network.

Here's what you need to know about Harry and Season 4 of Resident Alien.

What is Resident Alien about?

Based on a comic book series of the same name, Resident Alien follows an alien whose mission is to destroy all life on earth. Before he can complete his mission, his ship crash lands in the remote town of Patience, Colorado. He must find the lost parts of his ship so he can destroy earth and go home. To stay incognito, he takes on the human form of a local resident, Dr. Harry Vanderspiegle (Alan Tudyk) and is roped into a murder investigation of the town doctor. The show follows Harry's adventures as he searches for pieces of his lost ship, discovers kindness and humanity, all while planning revenge on his arch nemesis, a young boy named Max (Judah Prehn) who can see through his human cloaking device.

Where is Resident Alien filmed?

Resident Alien films in Vancouver, Canada and in the surrounding areas.

When did Season 3 of Resident Alien premiere?

Season 3 of Resident Alien premiered Feb. 14, 2024 on SYFY.

What happened in Season 1 of Resident Alien?

Season 1 of Resident Alien sets up how and why Harry arrives on earth. On a mission to destroy the earth and all of mankind, Harry's ship is hit by lightning causing him to crash land on earth with parts of his ship scattered in the vicinity where he landed. To remain under the radar while he searches for the missing pieces of his ship, he kills Dr. Harry Vanderspiegle and takes on his identity. He lives a quiet, unassuming life learning how to behave and speak like a human through Law & Order reruns until the local sheriff (Corey Reynolds) calls on him to help with the murder investigation and autopsy of the town doctor. Somewhat intrigued he agrees to help and is forced to deal with other humans in the process. As he takes on the role of the interim town doctor, he learns more about humans and their behavior. He comes across a young boy, Max (Judah Prehn), who is the only one that can see past his human cloak and the two become instant enemies but later become friends.

As Harry finds the missing pieces of his ship and the device that will destroy the earth, a nefarious military covert operation is on the hunt for him. Deciding not to destroy the earth, Harry is able to fix his ship and is on his way home when he discovers a stowaway on board.

What happened in Season 2 of Resident Alien?

When returning to Earth to bring back a stowaway—Max, Harry's ship was damaged and Harry temporarily lost his memory.

After Sheriff Mike and Deputy Liv (Elizabeth Bowen) discovered Harry's true form, he wiped their memories from that day. The memory gap causes Liv to question a few things which leads to her investigating the missing day.

Needing parts for his radio device so he can phone home, Harry attempts to romance Kate's (Meredith Garretson) cousin, Carlyn (Alex Borstein) so he can swipe her keycard and gain entry to her lab. Later, he and Asta (Sara Tomko) go on a hike in hopes of sending a message back to his home planet but several tag-a-longs hinder their plans.

General McCallister (Linda Hamilton) continues to interrogate Dr. Ethan Stone (Michael Cassidy), the doctor they mistakenly picked up thinking he was an alien.

Much to his surprise, Harry learns he has a human daughter, Liza (Taylor Rockwell), who arrives in Patience after rebelling against her mom and the real Harry's ex-wife.

Sadly, we said goodbye to 42, Harry's cephalopod cousin (voiced by Nathan Fillion), but we said goodbye in the most hysterical Resident Alien fashion as Harry tried to resuscitate his cousin by giving him mouth-to-mouth in front of a horrified Sahar (Gracelyn Awad Rinke) and her bewildered dog.

Harry and Asta headed to New York in search of a possible alien relative of his. They discovered an alien named Goliath (David Bianchi) who had a Banksy-like existence as an artist. Unfortunately, by the time they tracked Goliath down, he was dead, but he did leave a little present for Harry.

Their New York adventure ended with a dead Agent Casper (Mandell Maughan), goons from the mysterious Galvan/Powell Group hot on their trail with a connection to the real Harry and Dr. Hodges (Jan Bos), and an alien hybrid egg.

After returning home, the two must contend with well-meaning friends and family, the Galvan/Powell goons and the alien hybrid egg hatching.

With a Baby Harry (Andrea Geones) on the loose, Asta and Harry try to keep the party-goers in the cabin while Harry looks for Goliath's child. He eventually stumbles upon him as Baby Harry attaches himself to Harry with a message from Goliath warning him that there are other aliens on their way to Earth to destroy all mankind. The baby quickly escapes when Harry is fired upon by the goon from Galvan/Powell, and Asta is forced to kill him in order to save Harry's life.

And that's just the first half of season 2!

The second half saw Asta dealing with the repercussions of her actions as others in town deal with various events in their lives. The murder investigation was the main focus of the first few episodes of the second half of the season with Mayor Ben (Levi Fiehler) trying to shift the investigation to the nearby rival town of Jessup. The investigation also brought in a potential love interest for Sheriff Mike with Jessup Detective Lena Torres (Nicola Correia-Damude).

D'arcy (Alice Wetterlund) decided to get back into skiing but her old injuries caused her to seek pain meds which she then got addicted to, but after realizing she was on a downward spiral, she sought help from Asta.

Mayor Ben was trying to convince the whole town to get on board with the idea of a resort in Patience, but after Kate jumped off the resort bandwagon, he eventually saw the error of his ways and discarded the idea, much to Sheriff Mike's dismay.

We learned that Goliath was really Harry from the future and the message from him implanted into Baby Harry was a warning of what went wrong in Harry's timeline and what he could do to fix it.

Liv asked Peter the Alien Tracker (Terry O'Quinn) for help. When he arrived in Patience, it was a surprise not only to Liv, but also to Asta and Harry. Once enemies, Peter and Harry finally teamed up to infiltrate the government bunker which held Baby Harry and also Peter's son! Though the Alien Tracker lost his life saving his son, Harry "adopted" Robert (Paul Piaskowski).

Robert was later abducted again by the Greys. We also learned that Ben had been abducted (and likely not his first time) as well as his unborn child.

D'arcy learned of Harry's true identity. Who in Patience will be the next to discover Harry's secret?

Here's a two-minute recap of the first two seasons of Resident Alien.

What happened in Season 3 of Resident Alien?

In season 3 of Resident Alien, Harry fell in love with a Blue Avian (Edi Patterson) who came to serve him with an eviction notice to vacate Earth. After she finds herself stuck on the planet after D'arcy throws some fruit into her portal and breaks it, she succumbs to her attraction to Harry and the two become a couple. She is later forced to spy on him and collect his DNA after Joseph (Enver Gjokaj), a grey-hybrid alien threatens her family so she breaks up with Harry and leaves the planet.

After Kate is becoming more uncomfortable in their own home, Ben suggests a family getaway... to Yellowstone. Harry invites himself along for their family vacation and discovers the Greys master plan—to create a natural bomb that would alter the atmosphere so that only the Greys can survive in,  causing all life on Earth to cease. Kate, believing she has been abducted by aliens, goes to Harry to have the chip in the back of her neck removed. Harry hypnotizes her and when he brings her out of it, he allows her to remember everything. She tells Ben what she knows and Ben makes an appointment with Dr. Smallwood (Eleanor Walker) to have both of their chips removed, but when the time comes, Kate decides not to because she's determined to rescue their daughter from the Greys.

In order to stop the Greys, Harry develops a bomb which D'arcy steals in order to save the day. Unfortunately, she is captured by the Greys and the bomb confiscated. In an effort to save her and mankind, Harry and Asta, along with Bridget/Baby Harry, go to save her. D'arcy ends up helping Kate rescue the Hawthorne's baby girl and Robert, Peter's son, who is already on the ship, helps them to escape.

Back on Earth, Sahar makes Max apologize to Harry and call a truce but when Harry opens the door, Max screams because he sees not Harry the Alien, but a Mantid disguised as Harry! We then see Harry in the jail cell the Mantid once occupied. He's there with Bridget, in a cage of his own. Earlier in the Season 3 finale episode, we saw the Mantid devour another alien who had been put in the cell with him. Now, with the Mantid on Earth, he has a whole buffet to choose from!

Linda Hamilton (General McCallister)

After a supernatural encounter as a child, General McCallister now runs a covert operation seeking out alien life. Hamilton is best known for her role as Sarah Connor in the Terminator movies.

Fun fact: Hamilton's son, Dalton, played an infant John Connor in Terminator 2: Judgment Day.

Jenna Lamia (Judy Cooper)

Judy has lived in Patience all her life and is childhood friends with the rest of the gang - Asta, D'arcy, Liv, and Ben. She's not the sharpest knife in the drawer, but she provides viewers a lot of laughs.
