Read on for everything you need to know about the cast and who they play.

Elliot Page plays Viktor Hargreeves

Who is Viktor Hargreeves? Otherwise known as 'Number Seven', he's gifted with telekinesis and the ability to control sound waves. At the end of the first season, he caused the apocalypse - but he mellowed out in season 2 after his memory was wiped during a time-jump to the 1960s. In season 3, he came out as a trans man.

Speaking to Variety about the series ending, Page, who plays Viktor in the show, described the "odd" feeling of hearing Blackman shout "cut" for the final time.

"I think it didn’t even necessarily hit until later," he said. “To say goodbye to the cast and crew we’ve worked with for years and years, it’s definitely hard. You really become very familial."

Where have I seen Elliot Page before? The Oscar-nominated star of Juno, he's known for Flatliners, Inception, and for starring in the X-Men franchise as Kitty Pryde. More recently, he appeared in the film Close to You, on which he was also credited as a writer.

Tom Hopper plays Luther Hargreeves

Who is Luther Hargreeves? 'Number One', he's gifted with super-human strength, and has been in love with his adoptive sister Alison since they were teenagers – although this love faded in season 3 when he fell for Sparrow Academy member Sloane and married her.

Where have I seen Tom Hopper before? He played the ill-fated Dickon Tarly in Game of Thrones, and has appeared in the likes of Merlin, I Feel Pretty, and Tormented. He also had a main role in the series Black Sails and more recently has appeared in The Hitman’s Wife's Bodyguard, SAS: Red Notice​, Love in the Villa, and Space Cadet.

Robert Sheehan plays Klaus Hargreeves

Who is Klaus Hargreeves? 'Number Four' is gifted with the ability to communicate with the dead (although he's often felt like his gift is more like a curse, leading to substance abuse issues). He's highly charismatic, and charmed his way into becoming a cult leader in season 2, while in season 3 he discovered he has the power of immortality.

Blackman previously teased during an exclusive interview with RadioTimes.com revealed that the returning cast members were very keen to shape their character's journeys in the final run – singling out Klaus star Robert Sheehan.

"Robert Sheehan had a lot of say in how his character evolved," he explained. "I was going to take it a more comedic way in some ways and Robert really wanted to make sure he felt like it was real and grounded and it honoured who Klaus was."

Sheehan has also previously teased that his story will take a darker turn in season 4, and asked about he approached that, he recently told RadioTimes.com: "You talk them through, you try and not leave anything out, you try to make sure that they’re a good laugh and you’re not missing anything, and then you just go in and take each moment as it comes, one big long now, and try to remain present and listen. Let the writing, which is always good, shine through you.

"I wanted to show off a bit of acting prowess as well on the other side of things by showing a lot of extremes of emotion, ideally right next to one another. You see that mad, emotional flexibility that Klaus tends to have."

Where have I seen Robert Sheehan before? He rose to fame as an immortal superhero in Misfits, and has since gone on to star in the likes of Mortal Engines, The Last Bus, The Mortal Instruments: City of Bones, Killing Bono, and the National Geographic's Genius: Picasso.

David Castañeda plays Diego Hargreeves

Who is Diego Hargreeves? A skilled knife-thrower who was locked away in a 1960s psychiatric hospital in season 2, where he met and began to fall for Lila Pitts – whom he conceived a child with in season 3.

On what to expect from his character in season 4, David Castañeda told RadioTimes.com: "Diego’s very much in a space of not really seeing what’s in front of him, the idea of being a superhero and what validation that gives him."

Where have I seen David Castañeda before? The actor has starred in Switched At Birth, El Chicano, Sicario: Day of the Soldado, and Most Dangerous Game.

Emmy Raver-Lampman plays Allison Hargreeves

Who is Alison Hargreeves? 'Number Three', she's gifted with the power to manipulate reality just through her voice. A mother to a young daughter, in season 2 she also got married when she found herself stuck in the still-segregated Deep South in the 1960s.

Where have I seen Emmy Raver-Lampman before? The stage and screen actress is perhaps best known for her role in The Umbrella Academy, but she's also starred in the likes of Central Park, Blacklight and The Beekeeper.

Aidan Gallagher plays Five Hargreeves

Who is Five Hargreeves? Able to jump through time and space, 'Number Five' is in fact far older than the other Hargreeves siblings (due to his time-travelling), despite his youthful appearance. In season 3, it was revealed that Five was the founder of the Commission.

Speaking about how Gallagher had a big part in shaping his character's journey in season 4, Blackman previously told RadioTimes.com: "Aidan Gallagher also really wanted to make sure the character stayed true, that he wasn’t suddenly going to be laugh out loud funny - he’s an older man in the body of a boy, so he wanted to keep that loyal throughout the whole thing."

Where have I seen Aidan Gallagher before? Outside of The Umbrella Academy, he's best known for his role in Nicky, Ricky, Dicky & Dawn.

Ritu Arya plays Lila Pitts

Who is Lila Pitts? Gifted with the ability to mimic the powers of others, she is the adoptive daughter of The Handler (played by Kate Walsh prior to the character's death) and love interest of Diego – becoming pregnant with his child in season 3.

Speaking to RadioTimes.com about her journey in season 4, Ritu Arya revealed: "There’s a lot of depth with Lila now. It’s six years after we’ve seen them in the last season - she’s a mum, she’s in a marriage, she’s really put through the ringer."

Where have I seen Ritu Arya before? She's known for Humans, The Good Karma Hospital, Doctor Who, Sticks and Stones, Feel Good, Red Notice, Polite Society and Barbie.

Colm Feore plays Reginald Hargreeves

Who is Doctor Gene Thibeeau? One of the founders and leaders of an organisation called The Keepers – who want to bring about an event called The Cleanse in order to restore one true timeline.

He's also appeared in a range of films including The Founder, Bad Times at the El Royale and Civil War.

Justin H Min plays Ben Hargreeves

Who is Ben Hargreeves? In the first two seasons, Ben (gifted with the ability to shoot tentacles out of his chest) was visible only to his adoptive brother Klaus, having died before the events of season 1. In season 3, however, we were introduced to the alternate timeline version of Ben who is very much still alive.

Speaking about the character's journey in season 4, Justin H Min told RadioTimes.com: "We're seeing him after they've lost their powers. I think Ben is trying to find his footing. Obviously, he's the only surviving member of the Sparrow Academy left. He doesn't know where he quite belongs, if he belongs with the Umbrellas, or if he's kind of a lone wolf.

"And yeah, he goes through sort of an insane trajectory throughout the season. I think some questions that fans have been wondering about for a long time will finally be answered about Ben."

Where have I seen Justin H Min before? Min was acclaimed for his performance in the film After Yang, and other credits include Shortcomings, The Greatest Hits and a recurring role in Beef.
