Eternal Knight

Eternal Knight is the quintessential Ideal warrior, he fights without deceit or underhanded moves. He is a man who put honour above all else even his own life. Being an immortal superhuman makes this a lot more plausible

Chivalry
The Eternal Knight embodies the ideal vision of the knights of myth and legend and as such follows a strict code of ethics that prevent him from hurting the innocent and attacking anyone who isnt aware of the fight.

Death Transcendency
The Eternal Knight has transcended death and become a being of unimaginable power over death and undeath, and proceeds to use barely any of it thanks to the lack of honor in killing others outside of personal combat and the desecration of the dead.
