Denial

Denial is a secret 8th sin unlocked upon beating all of the sins 10 times. He is a reference to the Awesome face meme. When damaged, he has a small chance to put up a reflective shield that can only be pierced by piercing shots or things like Techology and Brimstone. He can also spawn a puddle of Yellow Creep. He will otherwise float randomly around the room, dealing contact damage.
