In a world where dipshits decide to make heroic characters really evil for seemingly no reason. One usually heroic character decides to blow up the goddamn universe for no reason:

Negasonic Teenage Warhead.

"I'm going to blow up the universe for absolutely no reason whatsoever!" said Longest Name Ever.

Why does she want to do it? Because humans can go screw themselves for all she cares... why does she think this? I can't tell you because it will ruin the joke.

NTW decides to spend 982738728738723872834784768468726734513578254782548157247821652469 days charging an explosion. She was desperate to destroy the universe, which I don't think she can do in any continuity ever, but for now, let's just continue this garbage.

She was bored as hell. She was spending years charging an explosion strong enough to destroy the universe and wasn't able to do anything else while charging this really large explosion.

Finally, after 982738728738723872834784768468726734513578254782548157247821652469 days (a.k.a: Probably longer than the average human life, don't ask, just roll with this unusual amount of time) NTW was ready to blow shit up.

"3… 2… 1…" HOLY SHITBALLS AN EXPLOSION OH MY GOD WE'RE ALL GOING TO DIE!

NTW's plan backfired and she died as well as rest of the universe… but to her, it was worth it, all to destroy humanity over the last slice of pizza.

NTW did this because someone took the last slice of pizza without asking.

Okay, what the fuck is wrong with her?

Her last thought was "I am the worst human being in existence… yay… fun… I'm going to die now… this is amazing… I've always wanted to sarcastically think to myself as a die suffocating in space, among the other horrible things happening to my body right now. This was absolutely worth it... I hate humans, they're worthless. They kill each other, they hate each other because of fear, and worst of all, they take the last slice of pizza without permission."

And then the universe was rebooted, reversing this evil douchebag's actions and erasing her from existence. Karma, bitch.

"No one with a name like 'Negasonic Teenage Warhead' deserves to live." Said the last surviving human who just so happened to have a magic suit with a 'reboot' button on it, I don't know how they survived this, but whatever, I just decided to make a fanfic where Negasonic Teenage Warhead is erased just because I don't like her code name. I don't care if it's a reference to Monster Magnet, it's an awful name.
