Check out the detailed character descriptions of the five characters below:

Luther (Hopper) was groomed by his father from an early age to be the leader of The Umbrella Academy – a responsibility that has always weighed heavily on him. He is resilient, a workaholic, and possesses the ability of heightened physical strength. Upstanding to a fault, Luther always tries to do the right thing, even if that means putting others before himself.

Allison (Raver-Lampman) is beautiful, elegant, and a formerly world-famous movie star who possesses the power of suggestion – anything she says aloud comes to pass. Her life seems perfect from the outside, but her ability has undermined every relationship she’s ever had. With her career on the decline and her marriage in shambles, she refuses to use her power as she seeks a more authentic life.

Diego (Castaneda) is a skilled, intense vigilante who has a real problem with authority. He isn’t as naturally strong or smart as his siblings, so he’s worked three times as hard for everything. Believing he should have been the leader of his family instead of his brother, he carries a massive chip on his shoulder that makes him hostile to just about everyone.

Number Five (Gallagher) appears to be a thirteen year old boy, but in actuality he is a fifty-eight-year-old man trapped in the body of a child. He doesn’t suffer fools and is the smartest person in the room. He’s haunted by the things he’s seen and done, and is on the verge of losing his grip on reality.

Klaus (Sheehan) is a drug addict and lovable mess of a human being and yet, if you ask him, any day now his life is going to turn around. He’s a classic “middle child” – a disarming pleaser who is seemingly everyone’s friend, but will rob you blind without thinking twice.
