Name: Jack Rabbit (Habit Rabbit)
Back Story:
Jack Rabbit was born and raised on the outskirts of Bunny Town. He was a Bunny School Delinquent and didn't have many friends. In fact, there was only one person he truly considered his friend. Joe Jumpington, a small bunny with a lot of attitude, was the perfect partner in crime for Jack. Jack and Joe spent their younger years involved in a life of crime, violence and gunslinging. Jack was given the nickname "Habit Rabbit", and Joe was given "Smokey Joe" on account of the fact that they both smoked way too many cigarettes. Since Jack lived on the outskirts of town, he was able to practice his gunslinging skills without much trouble, and together with Joe, had started to build a reputation for themselves.
Fast forward 8 years, and both Jack and Joe had become the best and most notorious gunslingers in all of Bunny Town. Catching the eye of the corrupt Bunny Government, the two best friends became top secret assassins for the Bunny Boss. They received training with exclusive technology not released to the public, and their skill surpassed even their own expectations. Their targets included important politicians, and anybody who threatened to take power from the Bunny Boss, ensuring that the he would be re-elected time and time again. The sheer secrecy of this conspiracy meant that Jack and Joe would have to live lives of solitude. They could not contact anybody including each other, with the exception of the Bunny Boss, when they received orders.
One day, Jack gets his biggest assignment yet: A man with a 6 million dollar target on his head. It turns out that one of the Bunny Boss' assassins had become a threat and needed to be killed. He finds the target, and begins the toughest fight of his life. After a six hour battle with bullets flying in every direction, Jack comes out on top. Jack goes to his enemy's body to remove his Government-issued Assasimask (a high-tech mask that was given to all assassins involved in the conspiracy to both conceal identity and improve accuracy.), and stares into the blank face of Joe, his childhood friend. Jack then realizes that if Joe had become a target of the Government, then he himself would not be far down the line. Jack takes off his mask, and leaves it on Joe's body as a message to the Boss, as if to say "catch me if you can."
Jack disappears and isn't seen for years. Currently, he's a contract killer under the name "Habit Rabbit", in memory of his friend Smokey Joe. He is a very mysterious bunny, only known by his nickname and his kill signature: a cigarette butt outed on the forehead of each and every one of his victims.
