A Ground Dragon type Digimon with big arms protruding from his back. The arms are said to have evolved from wings, allowing him to dig through the ground efficiently. Usually, he lives in tunnels carved deeply underground, and very rarely comes up to the earth's surface. Groundramon tends to inhabit the mines LoaderLeomon work in, and there is a very high possibility that the scales that cover his body are made from the very same material that LoaderLeomon search for in their work. Not much is known about this Digimon's ecology, since he is very ferocious in nature, and many who enter his lair never return. His special attacks are "Megaton Hammer Crush", which slams the hammer-like spiky iron ball on his tail into the opponent, and "Scrapless Claw", which slashes the opponent with the big arms on his back. His other attack, "Giga Crack", can only be preformed when he appears on the earth's surface: he creates an earthquake once he comes up to the surface, causing his opponent to fall into the separating ground below.

背中に大きな腕を持つ地竜型デジモン。背中の腕は翼が変化したものといわれており、効率よく地面を掘ることが可能である。普段は地中深くに彫ったトンネルに潜んでおり、滅多なことでは地表に出てくることはない。また、グランドラモンは希少なファンロン鉱の鉱脈に好んで生息する傾向があり、体を覆う鱗にファンロン鉱の成分を含んでいる可能性が高いことが分かってきている。性格は非常に凶暴であり、遭遇したもののほとんどが命を落としているため、詳細な生態が分からないデジモンの1体である。必殺技は背中の腕で相手を挟んでつぶす『スクラップレスクロー』と尻尾の鉄球で殴り倒す『メガトンハマークラッシュ』。地表に出てきた際には全身を地面に打ちつけて発生させた地割れに相手を落とす『ギガクラック』を発動させることもある。
