Tyutyumon is a member of Midnight in Digimon Fusion. Although he looks like a tiny, robotic mouse, he has only compressed his true data size, which is quite large. He works with his partner, [[Damemon ()|Damemon]], as a spy for [[AxeKnightmon ()|AxeKnightmon]], but while Damemon starts to express some reluctance in following their leader due to his manipulation of Ewan, Tyutyumon is more loyal to AxeKnightmon's goals.
