Peptis

In brightest day, in blackest night, all evil shall come from my sight. Let all those who praise The Shepherd, beware my power, Dark Green Lantern's light! In the far future of the Original Universe, Peptis was a soldier of F-Klak's army who was promoted to the status of Dark Green Lantern.

History
In the far future, in an unspecified point of the universe, F-Klak and Striborg gathered Peptis, Agga, and Memnon, three of F-Klak's best soldiers. F-Klak told the three soldiers that, due to their loyalty to him, each of them would be made a Dark Lantern and could choose which of the Dark Lantern Corps to join. When it was Peptis's turn to speak, he/she recited the Dark Green Lantern oath, so F-Klak enrolled him/her in the Dark Green Lantern Corps.
