Grumblemon (Frontier)

Grumblemon (Japanese: Grottomon) is a fictional character from the Digimon Frontier series. He was voiced by Tomohiro Nishimura (Japan) and Derek Stephen Prince (US). In the English version he is so stupid he can't form sentences properly, although he talks normally in the Japanese version.

Description
Grumblemon is the Legendary Warrior of Earth, using the power of AncientVolcamon. His Beast Hybrid form is Gigasmon.

Grumblemon is a proud figure who hates to be bossed around. He has an overconfident personality and insults his enemies at any chance he gets. He was the first of the Evil Warriors to surface, Slide Evolving to Gigasmon. He managed to take Tommy and Zoe's spirits. However, when Takuya first became BurningGreymon, Grumblemon lost his Beast Spirit to Takuya and Tommy regained his spirit.

He was eventually defeated by J.P. as MetalKabuterimon, who scanned his spirit as Zoe regained hers. Later, Grumblemon's both spirits were transferred into Takuya's D-Tector, so that Takuya could Hyper Spirit Evolve to EmperorGreymon.

A purified Grumblemon later appeared at Primary Village to help the other legendary warriors fight Crusadermon and Dynasmon.

Abilities
Grumblemon wears his handmade "Rot Armor" on his person and wields the "Grotto Hammer". He can also dig through solid rock and open a bottle that releases smoke that can summon Golemon to his command. As Gigasmon, he is a giant whose skin possesses a firmness that is above ceramics.
