Samuel Yen

Samuel Yen is a major antagonist in the Endling series. He is Dr. Terrence Wylder's assistant, and is often sent on the most dangerous missions.

Personality
Samuel is very reckless, and often acts without thinking of the consequences of his actions. Because of this, Dr. Wylder often sends him on missions where any other person would hesitate to take action. Despite his lack of empathy, he cares deeply for his Other, Yueng, and is heartbroken when she loses her vision to Stephen Wayne's Other, Brit.
