10 Most Disgustingly Grotesque Video Game Bosses

10. Mom - The Binding of Isaac

Binding of Isaac is as symbolically grotesque as you can get. Masquerading as a simple roguelike, the game explores deep psychological themes and never flinches at embodying some truly insane stuff. And it is via the game's bosses that some of the most skin-curling creatures are created.

However, when it comes to picking the most grotesque, there will inevitably be a lot of debate. But due to its symbolism, the rather spine-tingling design and motivation behind the boss, mom takes the cake. There is just something unnerving about the gangrenous leg, riddled with pustules, that makes the player uneasy.

It might not be the most demonically unflinching of bosses, but it is grotesque. Not to mention the backstory of abuse, the metaphorical meaning, and the fact that the entire game builds to this putrid moment.

It's just... creepy.
