The Geodude Line

Geodude
The Rock Pokémon
Type: Rock/Ground
Official Registration #: 74
Entry: A stony pokémon native to mountainous areas, particularly those of the Kanto, Johto, Hoenn, and Sinnoh regions. At rest, geodude look exactly like ordinary boulders, to the point where it’s not uncommon for even the most careful hikers to trip over them. It should be noted that not only will geodude become violently angry if you trip over them or their brethren, but also, geodude are extremely common pokémon to the aforementioned mountainous regions. To any trainers currently journeying through the mountains, the author wishes you godspeed.

Graveler
The Rock Pokémon
Type: Rock/Ground
Official Registration #: 75
Entry: The evolved form of geodude, by battle experience. Wild graveler subsist entirely on rocks. It will consume at least a ton of these on a daily basis, usually while on the move from the peak of its native mountains to the base and back again. Unfortunately, graveler are not particularly careful pokémon, and they, too, have difficulty distinguishing ordinary rocks from the surrounding geodude. On the positive side, graveler are capable of managing geodude populations singlehandedly, so at the very least, geodude overpopulation has never been nor will ever be an issue to the human race.

Golem
The Megaton Pokémon
Type: Rock/Ground
Official Registration #: 76
Entry: The evolved form of graveler, via trading. This boulder-like pokémon’s shell is so hard it can withstand high-powered blasts, including the ones it generates itself. For this reason, it prefers traveling in this manner, propelling itself from mountainside to mountainside through the force generated by Explosion. A golem falling from the sky is not an uncommon occurrence in the harsh environment of the Johtonian mountains, so to any trainers currently journeying through that particular region, the author wishes you godspeed especially.
