Grumblemon

Grumblemon is an Ogre Digimon. It possesses power over Earth which bears the might of AncientVolcanomon. Various weapons and armor are brought to life from its large hands and thick fingers, and its craftsmanship is practical yet artistic. The Grotte Armor that it wears and its main weapon, the Grotte Hammer, are both the handmade Grotte-brand. It prefers to act alone since it hates being ordered about, however its artisan pride is such that once it recognizes someone's true merit, it will obediently abide them, and immerse itself in its own work. Although it's not very intelligent, its pride towards its work is intensely high and it has a strong tendency to take the opponent lightly. It also has a technique which creates Golemon using the earth around it and orders them to attack.
