The Iron Lily [Boku no hero Academia Next Gen]

Walls can be truly scary

Especially ones you build yourself.
Especially the physical ones.

Out of all the walls I've seen, that one was the most horrifying. Filled with screams of blood and horror, the metal alloys in the vehicles and soil had merged and rose together in an epic wave of destruction and entrapped the poor souls, murdering, suffocating the unlucky ones slowly. I recognized it immediately as my own quirk. How ironic. My own mother pushed me in front of a car because my quirk never developed ... only to be saved by that very quirk. Ha. If you could even call that "saving" me.
Perhaps it would've been better had I died that day.

Instead, a red alert sounded as the "heroes" came to save us all. I mean, the poor people entrapped and spectating. Not me. I of course, was the "villain" of that event. Poor poor people who, through no fault of their own were forced into seeing such a disaster, caused by an absolutely horrible and evil villain.
The heroes covered it up that it was only a six-year-old girl who was capable of such mass destruction. The media were simply told it was the first appearance of a deadly villain, that they, of course had taken care of.
They didn't want to tell the world that a six year old's quirk anomaly killed dozens. However, they didn't mind telling the world that an unknown villain had bested them and murdered dozens of people in cold blood. Sure makes them look better, huh.

So any future crisis was averted, and my future was now a danger zone.
