Silver Bullet used to be a happy, childish, enthusiastic Killjoy. Working alongside her brother, Toxic Bomb, the two were unbeatable. Or so they thought. Bullet became cold after her brother's death. Hellbent on revenge, on seeking out the Killjoy group that took the only good thing she had. Kobra Kid had to grow up too fast, hoping to give his brother the bliss of immaturity. He trained way to hard, never joined in the other Killjoys' fun, and kept to himself. He never denied the fact that he chose this tough life, but began questioning if his sacrifice was really worth it. Two people, both broken. Could they be the only ones who could fix the other?
