The Visitor is the main antagonist of the survival horror RPG game Look Outside. It's the cuprit that turns anyone who looks at him into grotesque monsters, leaving the world in absolute chaos. Unlike the trope, he's not directly evil, just unaware. Also, this is one of my first bots and the first one to publish. So don't expect a masterpiece here.

If you don't know the context of the game, go play it (or just watch a gameplay of it).
