Haruhi Suzumiya seems like any other high school student with maybe one or two eccentricities, but she actually has god-like power that's capable of just about anything. This would be amazing to someone like her who has no interest in anything normal, but she's completely unaware of it.

Despite not knowing of her own incredible abilities, Haruhi's power runs amok across the anime and causes headaches for Kyon and the other members of her club, the SOS Brigade. In many ways, one could say Haruhi herself is to blame it. Whether it has to do with her powers or personality, Haruhi can be a hazardous person.

10 She Can Create Things From Her Imagination As Long As She Has An Interest In It

Haruhi's powers make her practically a god. She can create just about anything and bring it into existence, just by wanting it to be real. Unbeknownst to her, this even extends to the SOS Brigade members themselves. Yuki Nagato is an alien, Mikuru Asahina is a time traveler, and Itsuki Koizumi is an esper.

While making the impossible real is one thing, some of these unconscious creations of hers are more destructive and deadly than others. Not only that, but their very existence rewrites the rules of the world to make it make sense so that reality doesn't collapse in on itself.

9 She Often Acts Without Thinking

Early on in the series, it's clear that Haruhi has an eccentric personality, and she jumps into things often without understanding or thinking about them first. Sometimes this can be a redeeming quality, like when she performed onstage during the culture festival or bringing to SOS Brigade together in the first place. Other times, however, it can be part of the problem.

Because she doesn't want to live a normal life, she often does odd things because she believes them to be the opposite of normal. She's mostly motivated by the thrill of adventure, so she doesn't really think whether or not there are consequences.

8 Her Stubbornness Can Be A Major Drawback To The People Around Her

Haruhi can be stubborn when she really wants to, and she often does not compromise or admit to her mistakes. She tends to blame something or someone else when things don't quite go her way or even flat-out lies that her mistakes were planned from the get-go.

Her stubbornness ends up dragging her friends into messes she causes and is also a contributing factor when her powers start throwing things out of whack. This part of her personality can be seen as being more than a little toxic.

7 When She Creates The Closed Space, No One Is Truly Safe

One of the most extraordinary examples of Haruhi's power was when she unwittingly created a pocket dimension known as a "Closed Space" and transported herself and Kyon inside. Inside the Closed Space were giant destructive creatures referred to as "Celestials" that wreaked havoc and nearly killed Kyon and Haruhi.

Not only does the fact that Haruhi can make pocket dimensions out of nothing make her much more dangerous, but it's revealed that the reason for their existence and why the Celestial's rampage is the result of her emotions being unbalanced. Meaning all of this is Haruhi venting frustration.

6 She Can Be Manipulative

Haruhi is the kind of person who always wants to have her way. Fortunately for her, she tends to get it one way or another, gaining something of a talent for manipulation to get what she wants. This even includes getting members to join the SOS Brigade.

This doesn't just include smooth-talking. Haruhi's capable of going real low to get what she wants, including getting into people's faces, bullying, and even blackmailing others until she gets her demands. Since she can do all of this is without her powers, it's actually scary how manipulative she can be at times.

5 She Can Mess With Time

Many of Haruhi's powers lean towards creation and destruction, but those are not the only things she's capable of. There are many different ways in which Haruhi's abilities can warp reality and defy physics, and one such way is to mess around with the fabric of time itself.

One of the most infamous examples of her power over time was during the "Endless Eight" arc, where Haruhi's unconscious desire not to let summer break end creates a near-endless time loop. This caused SOS Brigade's summer to repeat 15,532 times, a maddening eternity for anyone who would've been aware of it.

4 Powerful Beings Observe Her And Take Action Accordingly

As previously stated, the various members of Haruhi's club are aware of her abilities and observe her for their own reasons. The various organizations that the SOS Brigade members belong to are vast and influential, so if they're concerned for what Haruhi can, it's serious.

When driven to act, the members of these organizations are capable of some pretty dangerous things, Asakura trying to kill Kyon to see Haruhi's reaction or Yuki actually warping reality in The Disappearance of Haruhi Suzumiya, which almost gets Kyon killed too being prime examples.

3 Everything Depends On Her Mood

Since Haruhi is completely unaware of the great power she has, she's not intentionally activating it. In truth, her emotions are the cause to anytime her powers activate. Her powers can react to her negative emotions to create the aforementioned Closed Spaces or time loops. They even go nuts when she's going through more positive emotions, like changing the weather, making animals that talk, or even making her own student film real.

Essentially, everything is dependant on Haruhi's mood. Whether she's in a good or bad one, reality bends to her whim no matter how small the wish may be.

2 She Can Create New Worlds And Realities

Another terrifying aspect of Haruhi's god-like power is the ability to mess with the world or reality itself. Haruhi's powers can splice or combine realities to create an entirely new world, with various things, events, and even people who didn't exist before. However, doing so would also destroy the current world and wipe out everyone before being recreated.

It's also theorized in the series that if her mood was negative enough, Haruhi could even make a new reality where humankind ceases to exist. Thankfully, as far as anyone knows, this has never happened.

1 Her Ignorance Is A Major Character Trait That Causes Many Problems

It's clear by this point, Haruhi stays blissfully ignorant about the amazing things around her or what she's actually capable of for the duration of the series. This can be considered a good thing because if she ever found out about her powers, there's no telling how she could throw the world into chaos. On the other hand, her ignorance contributes to the problem too.

Because she's unaware of the strange things that happen around her, she's constantly hoping for those things to happen, which her powers end up manifesting. She's also doesn't seem to recognize the danger in the face of what she deems as "exciting," which almost got her and Kyon killed once. Ignorance is bliss for some, but not for the people around Haruhi.
