Oceiros the Consumed King, Oceiros goes through the first half of the fight holding what appears to be nothing in his hand, giving the impression that the baby named "Ocelotte" is either invisible or simply does not exist and is just a delusion in Oceiros's mind.
However, there are several files still in the game data (including model, model-skeleton, textures and sound files) that show at one point, there was indeed a baby held in his hand. The most likely reason the baby was removed in the final game is because it would have been considered "too graphic" for various game-rating boards, as the baby is killed mid-fight in a very explicit manner.
