Character from Shovel Knight. Like most of the other knights of the game, most of his features are hidden, in his case under a hooded robe and his titular plague doctor mask, though it can be assumed from his exposed hands and feet that he is very skinny and has green skin. He uses a wide variety of bombs.
Originally a boss enemy, he becomes playable in the Plague of Shadows DLC with his own story revolving around creating the ultimate potion and impressing his love interest Mona.
