Atomic

In a dark, industrial setting, a man in a black suit is attacked by a figure in a dark cloak, who then transforms into a monstrous creature with a long, pointed head and glowing eyes, before being shot with a glowing green energy blast. The creature is then seen in a dimly lit room, followed by a close-up of a bullet with "GOODBYE" engraved on it, and finally, the creature is shown in a dark environment, being attacked by a man with long hair and a black outfit, who is then seen in a cityscape with a sword.
