Titanic Ant, known as Giant Ant in Japan, is the guardian of the first Your Sanctuary location in EarthBound, Giant Step. It resembles a large Black Antoid, and was probably altered by the power of Giant Step.
The Gigantic Ant, a palette swap of the Titanic Ant, appears much later in the game.
The Titanic Ant is probably the most soul sucking enemy in the entire game.
