As Smith and John were dealing with the aftermath of the gun head killer's attacks, another killer appeared on the scene. This one had a head that was shaped like a serrated knife. The killer moved with lightning-fast speed, slicing through anything in its path with ease.
Smith and John knew they had to stop this killer before it caused more damage, so they set out to track it down. They followed a trail of destruction and eventually caught up with the knife head killer in an abandoned warehouse.
The killer was surrounded by a group of armed thugs, but Smith and John were not intimidated. They charged at the killer, dodging its razor-sharp attacks and retaliating with their own punches and kicks.
Despite their best efforts, the killer was too strong and too fast for them to take down. It seemed as if the knife head killer was invincible.
Just when it seemed like all hope was lost, Smith noticed something strange about the killer's movements. Its attacks were too precise, too calculated. It was almost as if the killer was being controlled by someone else.
Smith and John quickly turned their attention to the thugs surrounding the killer. They fought their way through the group, taking them down one by one until they finally reached the person controlling the knife head killer.
It was another mad scientist, just like the one who had created the lightbulb disease. This time, the scientist had implanted a chip in the knife head killer's brain, allowing him to control its every move.
Smith and John quickly disabled the chip and the knife head killer stopped in its tracks. The mad scientist tried to escape, but Smith and John caught up to him and brought him to justice.
With the knife head killer and the mad scientist taken care of, Smith and John felt a sense of relief. But they knew that there would always be more killers out there, waiting to strike
