Personality and Traits
Chen would develop an incredibly eccentric and mysterious personality, often instructing others with cryptic hints and would often avoid being straight-forward, confusing everyone with his strange methods and ways. Wise because of his years of experience, Chen had an enormous amount of forethought and skilled intelligence, triumphing over several enemies as a result. Incredibly graceful, even when losing, Chen would be willing to sacrifice his life under any circumstances to protect others.
