Sam started taking out the research results he had on the lycans, giants and the shapeshifting demons.
The three species that he had encountered in one of the war missions and the three species that he killed a lot of. All these three has one thing in common, the transformation.
The Lycans transform into the beast type humanoid form, the giants increase in size and the shapeshifting demons, well.. Shapeshift.
And all of these are inherent and genetic.
When Sam first came across these creatures, he wanted to understand the genetic concepts very clearly. He wanted to see if he could find any applications with this. His scientific curiosity made him do a lot of extensive research.
He never really thought of using it on other living species though.
