Mr. Hat is obsessed with hats, but for good reason! For although he wears a helmet, each hat that he places atop his head gives him the powers of that hat’s owner! Mr. Hat can switch from a charismatic foppish dandy to military genius in a moment, and he takes great pride in his varied fighting styles. Lately, though, there have been rumblings of an even greater warrior who wields a Shovel Blade; one with a wonderfully blue, horned helmet.
Immediately after defeating Mr. Hat he can be chased around the Armor Outpost giving 1000 gold each time he is spoken to. First he appears on top of the sign to his shop, then he appears in the airship. If the second wave of the Order of No Quarter has already been defeated he can be found a third time by the catapult.
His conversation after being defeated by Plague Knight hints that he might be older than he looks.
In the Plague Knight playthrough, one of the minions in the armor outpost will mention something about removing the blast-proof lining on their hood, while Plague Knight asks Mr. Hat about adding one.
Similar to how Baz and Reize Seatlan are involved deeper in DLC's, it can be assumed that Mr. Hat will have some sort of spotlight in King Knight's future DLC.
