**Klaus Hargreeves**, formerly known as Number Four , was born in Pennsylvania, U.S. He was adopted by Sir Reginald Hargreeves and was trained in the Umbrella Academy.

## Powers:

**Mediumship:** Klaus (while sober) had the ability to communicate with spirits those who are in the afterlife. Ironically, he is afraid of the dead, so he uses alcohol and drugs to self-medicate and keep his powers dampened. Although, often throughout the series, Klaus is shown talking with his deceased brother, Ben, who seems to be the only spirit he is not afraid of. When speaking with Sir Reginald in the afterlife, Klaus was told that he had barely scratched the surface of their power's potential. As a result of the reset universe, he, alongside the rest of his family, no longer possesses his powers.

* **Evocation:** Klaus was also able to conjure spirits and manifest them into the real world. In his first attempt, when trying to summon Sir Reginald at the funeral, Klaus stated he couldn't do it because he was high. Also, because Reginald was too stubborn to get a hold of. With his newfound attempts to remain sober, Klaus was able to physically interact with Ben's spirit for the first time. This later further evolved where he was able to manifest Ben's spirit into the real world, though temporarily. In an alternate 1963, he was able to conjure deceased American soldiers into fighting Soviet soldiers. After he was blasted back by Lila's energy wave, Klaus was also able to conjure two spirits into catching him in their arms just before he hit the ground.
	+ **Spectrokinesis:** Klaus was able to manipulate and destroy spirits. In the episode 'Auf Wiedersehen', he was able to destroy spirits that were chasing them in the graveyard.
		- **Communing:** Klaus was able to communicate with spirits.
		- **Spirit Summoning:** Klaus was able to summon spirits from the afterlife in order to communicate with them and/or to do their bidding.
* **Death Whisper:** Klaus was able to listen to the voices of the dead.

**Retroactive Immortality:** Klaus used to be immortal in the sense that when he died, he wouldn't stay dead. This is the result of self-resurrection. In the episode ‘The Day That Was’ Klaus followed his drunken, desperate brother Luther in an attempt to stop him from getting high. He finds him at a rave high anyway and dancing with a woman which leaves an angry boyfriend. Klaus jumps on the man's back but gets thrown off and hits his head. He is shown to wake up to a girl/God apparently in the afterlife and she claims that ‘he doesn’t run her the right way’ and so she doesn’t like him. She tricks him into meeting Reginald where his dad then confirms that he's ‘already dead’ but later on he wakes up on the dance floor after being sent back to life. Klaus subsequently discovered that he was effectively immortal, resurrecting himself every time that he died. While in the beginning it took around 22 minutes for him to come back from the afterlife. After training with his father, Klaus could now revive himself almost instantly. However, he lost this ability after the universe was reset, making him mortal again.

* **Self-Resurrection:** Klaus was able to revive himself upon death either instantly or after some time. Originally, he would stay dead for a long time (roughly an hour), but after dying more times, he was able to resurrect himself faster and could self-resurrect in a matter of seconds.
	+ **Regenerative Healing Factor:** Every time Klaus came back from the dead, all injuries that his body has sustained would slowly heal, including broken bones and internal damage. If his body is disintegrated to dust, it will materialize a new one out of thin air once he comes back from the dead.
