Clement was the warden of a jail, beneath which the U.S government had constructed a vast underground laboratory where it was conducting secret research with a view to creating stronger, more resilient soldiers.
The project was eventually forgotten about and the laboratory remained sealed under the prison until Clement discovered it.
Clement found a use for this laboratory - he was scared of losing the one person in the world he cared about - his mother. The game later reveals that Clement and his mother were engaged in an incestuous relationship. He discovers within the lab the secret project known as "Formula X" with which he hopes to grant his now aging mother a new lease on life.
To do this, he uses Papa Caesar to test and refine the formula. He then proceeds to transplant his mother's brain into the youthful body of Varla Guns. Unfortunately, the procedure is a failure and Mother/Varla mutates into a giant abomination.
- Clement's voice actor, Vince Mola, also starred in the psychological thriller Head Trauma.
