The Abrupt Demise

Name: Roger V. Nitroglycerine
Race: Human.
Gender: Male
Description: Roger wears a custom heavily padded jacket at all times, that helps keep him cushioned and stable. His pants are also heavily padded. He's got neck-long red hair, because scissors make him nervous. He's got a rather pale complexion, with a bit of a sickly green tinge to it.
Roger is overall a nervous guy. Overly cautious about everything he does, he's not much of a thrill seeker, and would rather do nothing but sit down and not move for the rest of his hopefully prolonged life. This is unlikely.
Weapons/Abilities: Roger was injected with an experimental drug to help improve reaction time and speed. It worked! It also made him highly unstable. In a chemical way. It's been determined that if he's upset too much (physically, not emotionally), he and anything around him will be taken out in a large firey explosion. He'd rather this ability not get used.
Backstory: Roger needed money, so he signed up for a secretive test program. Then he learned he was in danger of exploding violently. He was upset by this.
