The base’s training pool doesn’t satisfy El Ray’s need to be in the water.
Mixing the DNA of Human, Manta Ray, Electric Catfish, Electric Ray, Sailfish and Stingray we created El Ray to lead the other Hybrid-Humans of the Delta series. While not as large as some of my other subjects, he makes up for it with bio-electric defensive measures taken from the DNA of eels and catfish as well as a poisonous stingray barb. El Ray was created to be an amphibious soldier able to breathe on land or under the sea.It’s likely a natural biological desire, but we cannot risk him discovering the truth about our experiments or curiosity might kill the catfish.
