Polluxis Psyche (Empath stories)

Polluxis is a character who is part of the EMPATH: The Luckiest Smurf story series. He is a Psyche who was Empath's opponent in a training match during Empath's final year in Psychelia. Empath was prompted to kill Polluxis, but when his opponent was down and ready to be killed, Empath refused to do so, and thus Polluxis was revived and the match was prolonged until either combatant was killed. Eventually seeing that there was no way out of this situation, Empath ultimately killed Polluxis, which left such a stain on his soul as the first Smurf in centuries that has ever killed another. Polluxis appeared unto Empath in the story "The Innnocence Of A Smurf" as a constant phantom presence to confront Empath of his guilt and to make peace with himself.
