Sluj is a genetically engineered creature, based on the DNA of his own creators: Dr. Carolyn Sheridan and Dr. Jerry Baker. He was programmed to adapt to its environment, surviving in either air or water. It could manipulate its own form to various shapes and absorb raw sewage into its own body mass. It had telepathic abilities but needed to engulf humans into its body in order to use it on them. It was able to mimic their thought processes and increase its own intellect. The humans were held in suspended animation. Sluj was destroyed when Namor released a gene scrambling virus inside the center of its body.
Creation
Sluj was created by John Byrne in 1990 and first appeared in Namor The Sub-Mariner # 6.
