Each member of The Umbrella Academy has its own unique superpower. From super-strength to time travel and seeing the dead, the Hargreeve's siblings are extremely powerful in their own ways. Five can time travel,  Ben could summon creatures from other dimensions within his body, Diego has super-human precision and Vanya can essentially turn sound into full force powers and destroy moons.

Allison and Klaus are arguably the most powerful of the siblings if they use their powers to their full potential. Allison can rumor anyone to do anything, while Klaus can interact with the dead, but who is the most powerful?

Allison: She Can Influence Anyone

Allison has the power to tell anyone to do anything. Using season two as an example, she said that she heard a rumor Diego punched himself in the face, which he does a second later.

That is an extremely powerful tool to have. The only person she can't control is Lila, who can somehow replicate her powers.

Klaus: He Can Communicate With The Dead

Klaus can essentially interact with the dead, something that must be both awesome and traumatizing, which explains his personality perfectly. It's fun to imagine all the kinds of people that he could have met while using those powers.

It makes sense that of all the things he could have done in the 1960s, he formed his own cult.

Allison: Her Powers Are Basically Limitless

There really is no limit to what Allison's powers can do. She could rumor herself in and out of any situation, she could prevent herself from getting into trouble because she could rumor someone into forgetting she was there.

She could do so many things with her powers, and hopefully, she'll use them more in the coming season.

Klaus: He Gets To See Ben

Ben died during a mission when they were all younger, and although no one truly knows how he died, it was clearly traumatic for the whole family. Since Klaus can communicate with the dead, he gets to interact with Ben, who sticks around after he dies, until he truly disappears in season two.

Klaus is the only one in the family who can actually see Ben, with the only exceptions being Diego who talks to him when he's possessing Klaus, and Vanya who he helps before he disappears. Klaus and Ben have a bond unlike any of the other siblings, and they also have some of the best scenes of the show together.

Allison: She Can Get What She Wants

Allison has the power that everyone would want. She only needs to say a few words in order to get what she wants. This is probably partly why she sort of stops using her powers in season two, because of how afraid she is of hurting the people she loves with her powers, even though she's pretty careful with what she says.

Ray gets suspicious of her from the moment she starts saying 'I heard a rumor'.

Klaus: He Can Create An Army

As seen in the opening sequence of season 2, Klaus could potentially harness the dead to create his own army. Hopefully, he'll be able to use his powers to their full potential in season 3, as this would be something really cool to see.

Klaus is often too unbothered or just doing other things, like running a cult, to use his powers to their full ability.

Allison: She Could Change History

While Allison is dropped into the 1960s and the middle of the Civil Rights Movement, her powers mean that she could potentially change things for the better.

Although she doesn't go this way and chooses not to use her powers at all until her husband Ray starts to get suspicious, it would have been interesting to see what could have changed if Allison has used her powers during that time.

Klaus: He Can Use His Powers To His Advantage

Klaus is unique because he can see things that others can't. He uses this to his advantage in season two, an example being when he gets Ben to lift him up in the air, which gives off the appearance that he's floating.

This makes his hundreds of cult members believe that he was actually floating. Some people might think he's crazy or magical, but he really just has Ben holding him up.

Allison: Her Powers Are The Easiest To Use

Out of all the Hargreeve's siblings, Allison's powers might be the simplest and easiest to use. While it takes a whole lot of stress for Vanya to use her powers,  Allison only has to say "I heard a rumor" for anyone to do as she says.

This is demonstrated perfectly when she and her husband Ray go shopping in a shop that is segregated, and she tells the shopkeeper that she heard a rumor he let Ray try on anything he wanted.

Klaus: He Could Get Closure

It's a well-known fact that Reginald Hargreeves wasn't a good father, and when they're all brought together because of his death, none of them really got closure for the things that he did to them. Klaus is the only one who could potentially speak to his father again, which he does in season one.

Klaus doesn't have to properly say goodbye because he can always attempt to see them, something he tries to do with Dave, the man who he's in love with who dies fighting in Vietnam.
