Roggenrola
The Mantle Pokémon
Type: Rock
Official Registration #: 524
Entry: A small, boulder-like pokémon native to Unovan caves. Roggenrola are easily recognizable by two features: the hard-as-steel skin covering its entire body and the hexagon-shaped ear hole drilled into its front. The author will pause here to give the reader time to get over their inevitable astonishment that the hole in the front of a roggenrola is, in fact, an ear and not an eye or a mouth.
Boldore
The Ore Pokémon
Type: Rock
Official Registration #: 525
Entry: The evolved form of roggenrola, by battle experience. After having trained deep within the harsh conditions of its underground home, boldore has attained power too great for its body, and thus, upon evolution, orange crystals have burst through its steel-like skin to contain its excess energy. And yes, those are two ear holes.
Gigalith
The Compressed Pokémon
Type: Rock
Official Registration #: 526
Entry: The evolved form of boldore, via trading. Upon evolution, gigalith’s crystals not only retain the ability to store their host’s excess energy, but they are also capable of collecting solar energy on the rare occasions that this pokémon is on the surface. Once enough energy has been collected, gigalith can compress this energy into its core and fire it off as a destructive ball of light. And yes, those are still ear holes. This pokémon has no eyes, and its mouth is on its underside. These are just facts the reader must become accustomed to, should they wish to train any member of this evolution line.
