C'uk

C'uk was the arch-nemesis of Drepp back on his homeworld.

Chapter 6: Maskirovka
When describing the backstory of Drepp, the narrator mentioned a character named C'uk, who was a criminal on Drepp's homeworld who ruined his life somehow. It was because of these events that Drepp decided to rededicate his life to fighting crime, and became a vigilante to seek revenge against C'uk. Drepp eventually defeated C'uk and brought justice to his planet, but found that the criminal's defeat did not bring him happiness; instead, he found that his life was lacking in purpose now that C'uk was no longer a threat, so he became depressed.
