Roggenrola is a roughly spherical Pokémon discovered a century ago in an earthquake fissure. Its body is blue and covered in large, smooth facets. It has a hexagonal, yellow artifice in the center of its body, leading to a hexagonal opening that functions as an ear. Roggenrola has a brown, rocky oblong atop its head, and similar brown rocks that serve as feet. Its body houses an energy core; due to compression underground, both this core and Roggenrola's body are as hard as steel.
Roggenrola is born deep underground, and compares its hard body with that of Geodude and Carbink. As stated by Cilan in Where Did You Go, Audino?, Roggenrola has sensitive hearing and can hear sounds that are inaudible to humans. It tends to follow the sounds it picks up with its lone ear, panicking if these sounds cease. Dwebble is a natural enemy of Roggenrola. Sometimes Rhyperior mistakes this Pokémon for an ordinary rock and fires them through their hands.
In Gotta Catch A Roggenrola!, fourteen Roggenrola were targeted by Team Rocket. However, they were rescued by Ash and his friends, with the help of a fifteenth Roggenrola who was part of their group. They reappeared in a flashback in Explorers of the Hero's Ruin!.
A Hiker named Andy uses a Roggenrola during his Triple Battle with Black in Black's First Trainer Battle. However, he was defeated after Andy became dehydrated.

Roggenrola is a corruption of rock and roll. It may, more specifically, be based on the pronunciation of "rock-'n'-roller" (a slang term for musicians who play rock and roll) in certain dialects of English.
Dangoro may be a combination of 団子 dango (a Japanese dumpling) and ゴロ goro (grounder). It may also derive from ゴロゴロ goro goro (onomatopoeia for the sound of a boulder rolling).
