Here's an example of the sort of thing to post regarding character concepts. I tried to pick something it was highly unlikely anyone else would do. This is the sort of thing that will end up in the rogues gallery.

Appearance
Jackson is the fat kid. He wears spectacles and has freckles. He is of average height and overweight, with blonde hair and blue eyes. When he engages his powers, he swells up like a ball.
Personality
Jackson is cheerful and smart. He loves a good joke but is sensitive about his weight. He loves building robots and tinkering with computerized equipment.
History
Jackson was born in Liverpool in England. His family lives in a small house near the outskirts of the city. Jackson has always been the smartest of the children; his brothers and father are all in construction. His mother is a secretary for a law firm. His baby sister is only 10 years old. Jackson showed early affinity for computers and later took up making small robots for the "Robot Wars" circuit. He has become a regular fixture on the show.
At age 14, the blood test for the mutant gene came back positive and indicated that his powers would surface soon. Without enough money to enroll Jackson in any special institute to make sure he and others weren't harmed by his mutation, the Burton's kept Jackson in normal school. A few days after his fifteenth birthday, things rather... blew up. Literally.
Sitting in class, he suddenly puffed up. His clothes ripped as he became a human ball. Unable to control his power, local authorities cut out a wall and lifted the inflated boy from the school. He was stuck this way for nearly a week, during which he had to be fed and bathed. He was dreadfully embarassed and it still upsets him to think on it. To help him cope, his aunt and uncle let him move in with them on their farm for a few months, while he learned to control and adapt to his new found mutation.
The farm episode worked wonders for him. He regained his confidence and moved back home, and went back to school. While he got a bit of teasing, most kids just wanted to see what he could do. Despite having a very odd power, he was suddenly very popular. He became more popular when he foiled a bank robbery in Liverpool. Armed robbers entered the bank where he and his mother were. Scared for a moment, he suddenly inflated, knocking one of the robbers flying. The other two opened fire, and bullets simply bounced off him. Rapidly bouncing about the room, he crushed both robbers unconscious. It was all caught on tape, making him an instant local celebrity.
The armed forces gave him some tests, but ruled his powers to odd to be of any serious use. Thanks to his slight celebrity however, he has just received an invitation to the EPIC Institute, much to his excitement and his parents pride.
