Hazel is a hitman, whose job is to keep the timeline safe and steady. He and his partner Cha-Cha are supposed to stop anything that isn't supposed to happen from happening. They ensure that everything will play out like it was meant to.
Hazel is also a sucker for sugary treats. The duo of hitmen (who both wear cartoonish animal masks) are known for their love of delicacies, often taking time in-between their missions to feast on treats.
Hazel and Cha-Cha are trained hitmen who have carried out multiple murders. They live in and out of time, as they won't grow old.
The duo was murdered when the seancé, who they had kidnapped, possessed one of them and made him shoot the other, blowing his brains out.
