One day in the Davis household, there was a robbery . The Davis family heard shuffling downstairs so they went to investigate. When they wondered downstairs, they saw a man standing at the bottom of the stairs with a gun pointed at them. In that moment, the intruder shot the family and all was dead except the baby, Joey
That same night, there was a knock on Joey's godmother's door - she knew instantly, something was wrong. She answered the door to see little Joey just sitting on the steps.
In school, Joey always got bullied by his other classmates. But one day, when he was getting bullied he shot his bullier with a paralysis shock. She was no longer able to move, to act, speak, etc. She was paralyzed
When he went home, he talked to his "mother" and she told him to go save the world and fight the vampire in the underworld.
Davis ended up going into the underworld to fight the big vampire who was controlling everyone's bad emotions in the real world, and again - he shot her with a blast of paralysis shock. She no longer was able to controll the bad emotions
When he came up from the underworld, he was celebrated with cake and happiness.
