A Digimon with power over earth that bears the might of the Ten Legendary Warriors. Grumblemon’s large palms and thick fingers can produce various types of weapons and armor of both practical and artistic value. All of its equipment, from the Grotte Armor that it wears to the Grotte Hammer that is its primary weapon, is of the handmade Grotte brand. Preferring to act on its own initiative, Grumblemon hates taking orders, but it has the heart of a true craftsman. Once impressed by another’s skill, it will follow orders without complaint, losing itself in its work. Grumblemon isn’t especially smart, and since it takes a high degree of pride in its craftsmanship, it tends to underestimate others. Its two main special moves in battle are Snake Eye Break, by which it uses its Grotte Hammer to petrify and then smash foes, and Jack in the Box, by which it burrows underground to launch a surprise attack from underneath its opponent. However, Grumblemon also has the ability to fashion a Golemon out of the earth and have it fight instead.
