Disclaimer: TBoI is a game made for adults with a deeply dark and religious theme sprinkled throughout. Don't look further into the game if you are easily disturbed! Here we have one of the possible bosses for the basement level, and one of the first bosses ever added to the game. Originally appearing in the original Flash game The Binding of Isaac (and later in the game The Binding of Isaac Rebirth), Monstro is one of the most recognizable bosses from the franchise.
