Lester Johnson was thought that to have died at the wheel controlling the elevator in the Freedom city hotel. It turned out that he managed to survive, but was horribly disfigured due to the fire that J.B. started to wipe out the Stickie army led by Kaa.
He was nursed back to health by another survivor of the failed attack, a Stickie. Over the months that passed since the destruction of the hotel, he healed and gathered a small army of muties to help him continue Kaa's war. When he learned that Ryan Cawdor is in the Freedom mall, he decided to attack right there so he could get revenge. When the army attacked, and he confronted Ryan, they fought, and he was shot to death by Krysty. (Skydark, Freedom Lost)
