Mdk and owl

The Mysterious Druid Knight (and their companion Owl) is a secret boss in the indie first-person shooter game ULTRAKILL. They are found in the level 4-3: A SHOT IN THE DARK and are a reference to and voiced by the YouTubers Mandalore Herrington and Joy Young (Shammy). a combination of a stoic "mysterious knight" that increases its speed and a vulgar, more aggressive "owl" that shouts insults like “just fucking hit em!”
