Master Frown

Master Frown is the main Villian of Unikitty! He is a Doom Lord that is Unikitty's arch-nemesis. He is the antithesis of Unikitty. While Unikitty strives toward staying positive, Master Frown seeks pleasure in the suffering of others, sometimes taking it upon himself to ensure that everyone is just as unhappy as himself. This is carried to the point that he seems to enjoy being in a bad mood as well.
