Name: Leon Decker
Age: 17
Gender: Male
Quirk: When extremely agitated, his pupils would dilate, causing him to take in more light. After the cause of his agitation has come and left, he will have claimed to have "gone blind with fear." He typically shys away from cursing, though he will take exception to this rule if in pain, experiencing anger, or fear.
Appearance:
He had short black hair, with silvery-blue eyes. Typically, he sports a white t-shirt and jeans. His slim frame is stronger than warranted, and a lot more durable at second glance.
Some quick backstory: As a child, he was not sheltered from the horrors of the real world. When he grew up, he had an idea of what exactly to expect, but as time went along as well as he did, it had gotten worse and harder on children. Now a junior, he has suffered through most of what both the real world and the internet had thrown at him - but the onslaught continues, and he fears he may be coming to an end with his patience.
There, you can go ahead and use it as an example!
