The smiles first appeared to cause chaos among the U.N. The United Nations had just acheived World Peace. Kun Lan didn't want that. He then created the Heavens Smiles. The Killer 7 was contacted to kill these creatures. The Kiler 7 were led by a 'good' god, named Harman Smith. The Killer 7 had the power to see the invisible smiles, and get a chance to shoot them. The smiles appeared in nearly every evil plot that Kun Lan was involved in. And the Killer 7 were not far behind. After Kun Lan's death, the smiles were eventually killed off by one of The Killer 7,[2] Garcian Smith.
