Wicked K is a remnant of humanity in Darksiders and Darksiders II. He can be encountered multiple times over the course of both games as a optional boss. Wearing a top hat and speaking with an English accent, he is agile and fights with his cane in a fencer style.
According to Vigil Games' general manager, David Adams, Wicked K is a character that the designers had in mind for two years and is a caricature of Vigil's British contingent, added to the game in the final month of programming, as an in-joke.
