Notable Bio

Hailing mainly from the Unova region, with populations in Kalos, Alola, and Galar. the unusual looking Roggenrola line takes a role very similar to the Geodude line in the Kanto, Johto, Hoenn, and Sinnoh regions. Roggenrola are a relatively new Pokemon to Unova, and the surface world in general, having only appeared in the last 100 years above the surface due to a fissure in the area that would later be known as Wellspring Cave. Soon afterwards, Kalos and Alola reported sightings as well. The first morph, Roggenrola, is a small Pokemon slightly over a foot in height that is circular in shape and brown and blue in coloration, with a yellow section on the center surrounding a hexagonal ear, and a rocky crest on top of their heads. Their unusual features are due to the fact that their original habitat is deep under the earth, leading to their nickname of "The Mantle Pokémon".


Since they originally lived in a completely subterranean habitat, Roggenrola are completely blind, and as a result they use a form of echolocation to find their way around by sending out sonic pulses using their ears. These pulses reproduce their surroundings completely to the Pokémon, and are more or less as good as sight, with variation between individual Roggenrola. They can also use low frequency sounds to communicate amongst each other.

Roggenrola are powered by an metallic inner core, which is protected by one of the thickest cuticles out of any Pokémon. Simply put, due to their original environment being fairly pressurized, the outer skin of a Roggenrola formed from centuries of compacted soil is as thick as iron, and hard enough that the Pokémon cannot be knocked out by a single blow, making it capable of withstanding a direct horn jab by a non-blunted Nidoking horn completely unscathed. A Roggenrola’s shell will only increase in durability as the Pokémon evolves.


As for the core itself, it is located in the center of the Roggenrola in a holding container filled with a conductive fluid similar to battery acid in acidity. The core is also mildly radioactive, and its energy is transported throughout the Pokémon’s body through a system of canals similar to the organic circulatory system filled with a conducting fluid of much lower acidity. At this stage, the low energy requirements of Roggenrola means that the core is pretty much self-sustaining. However, as the Pokémon gets older, the core has to work harder to power it. If it doesn't evolve in time, however, the Roggenrola will enter a state of torpor to conserve energy and eventually "reboot" itself. One way this torpor state's duration can be hastened is through the use of cold temperatures, similar to the old trick of putting batteries in a refrigerator, though the majority of Roggenrola end up starving when their cores finally stop working.


Once a Roggenrola reaches a certain energy threshold, it will evolve into a Boldore. Standing at just under three feet tall, Boldore have a more elongated body than Roggenrola, with two ears, three legs, and a body covered in crystals created by energy from the core leaking out and solidifying in the open air.

Boldore live at even deeper depths than Roggenrola, and their new crystals often glow when their inner core overflows with energy. As a result, they can fire off this energy at assailants in the form of blasts of light; similar to how the Vanillite Line can use their bodies as lenses to fire beams of light. Boldore mainly spend their lives looking for mineral water deep underground, which is why compared to other Rock type Pokemon they have a lesser fear of water. However, significantly large bodies of water such as the ocean will cause a similar reaction to just about every other Rock and/or Ground type Pokémon. [[Trainer's Note:It should be noted that despite this lack of fear, they still should not be directly submerged, as apart from the danger of drowning prolonged submergence can damage their outer casing.

The final form, Gigalith, is an incredibly rare sight in the wild. Wild Boldore have to be put under high heat and pressure deep underground to undergo the evolutionary process, which can take decades to complete. For this reason, the vast majority of Trainers prefer to use the electromagnetic signals created by trading machines to facilitate evolution in their Pokémon.

Gigalith stand five inches less than six feet, with a quadrupedal body, longer, sharper crystals than a Boldore, and a distinct head with well developed eyes and a mouth, the former being a rather strange trait for a primarily subterranean creature. Gigalith crystals have a different lattice structure to that of a Boldore’s, allowing them to absorb as well as fire off energy. When solar energy is absorbed by Gigalith crystals, the Pokemon is capable of magnifying the solar energy gathered in order to fire off devastating blasts of solar radiation from its mouth. At least one Gigalith is recorded as being able to blow away an entire cliffside with the sheer power of its Solarbeam.

There exist Roggenrola that are purple in color unlike their blue brethren, and evolve into Boldore and Gigalith with blue crystals instead of red, due to a slight chemical difference in core composition. These rare Pokémon are greatly prized by collectors. There is also a phenotype of Roggenrola with relatively thinner outer cases, but gain increased speed in return. They eventually evolve into Gigalith capable of releasing sediment at will to create localized sandstorms. Rarer still are a subtype of Roggenrola that also have relatively thinner outer casings, but are capable of using sediment to fire larger, thicker rocks from their bodies.


Roggenrola and its evolutions are naturally found deep underneath the earth, with the majority of the population being located at depths impossible to reach at the time of this article. As for the Wellspring group, after reaching the surface they quickly established themselves within all of Unova's caverns through their tunneling system, the largest branches accessible by humans being known as the Relic Path and the Clay Road. Within Kalos they are far rarer due to the presence of the Geodude Line, with the largest population being found within the Reflection Cave. Within Hoenn, a population of Roggenrola has established itself inside the Fiery Path within Mt. Chimney, likely due to the clash between Groudon and Kyogre. In Alola, two populations are known from the Ten Carat Cavern on Melemele Island, and Vast Poni Canyon on Poni Island. Within mainland Galar, they can be found at the Galar Mine, Motostoke Outskirts, Route 8, and the drier parts of the Wild Area. They can also be found on the Island of Armor off eastern Galar.

Roggenrola tend to live inside their birth caves (See Courting and Childrearing) until they evolve, at which point they use underground tunnels created by Boldore and the occasional Gigalith to find a new cave to live in. These caves tend to have large supplies of water.


Roggenrola survive mainly on their cores, and as a result normally do not eat anything, although they will accept treats in captivity. Boldore and Gigalith on the other hand drink mineral water and eat ore, similar to the Aron Line's dietary habits, in order to maintain their far more high-maintenance cores. In captivity, Boldore and Gigalith can also be fed berries. The former can absorb them using their bottommost crystals, whereas the latter can just eat them like most other Pokémon.


Though Roggenrola and its evolutions are generally rather easy-going Pokémon, it would be wise not to antagonize them. The rocky bodies of the Roggenrola line make most attacks ineffective against them, forcing Trainers to go into prolonged battles with them unless they have Pokemon capable of piercing Roggenrola’s defensive shell.

Roggenrola may be small and slow, but they’re also very powerful for their size. If they cannot waddle away from a threat, or harden to the point that it gives up, they will fight against it using bone-breaking headbutts, kicking sand or mud in their eyes, or firing rocks from their ear hole at an assailant's head and/or chest with deadly precision.

Boldore and Gigalith can do everything Roggenrola can, but even stronger, and up their arsenal through causing rock slides, blasting out sediment to create sandstorms, firing pointed stone shards at opponents, surrounding opponents with rocks that slice into any allies that come to help, firing beams of light from their crystals, and firing rocks with such accuracy that they can knock flying or floating Pokémon right out of the air. As a last resort, they can overclock their cores so that everything around them is caught up in a catastrophic explosion. Apart from being temporarily knocked out, they will be left more or less unharmed, unlike their assailants, which may be left in pieces. The area around them may also turn into a small crater from the energy exerted in the blast.

In the case of Gigalith in particular, they can also use their solar radiation blasts or simply crush an enemy under their weight, if they’re close enough. Also, their crystals can leave pretty nasty wounds if a Trainer is careless while handling them. Luckily, their lack of speed means that simply running away is enough to cause them to leave you alone, though their ability to sense sounds also means that if one really wants to hurt you, it's still best to get as much distance between you and them as possible. [[Trainer's Note: Compared to the rest of their bodies, the soles of a Roggenrola Line member's feet are relatively weaker in terms of defensive strength, though not as bad as Tyranitar. The pain from say, a nail being stuck in a foot can cause them to go on wild rampages however.]] If running is impossible, the regular Rock type weaknesses still apply, and while the rock shells of the Roggenrola Line are superb at resisting physical assaults, they don't fare quite as well against energy-based attacks.

On the rare occasion that something breaks through to the core, it is immediately met by the acidic conducting fluid well, as well as mild radiation. While short-term exposure is relatively harmless, long-term exposure can lead to health complications later on in life. [[Trainer’s Note: Specialty stores sell lead casing for special cases such as this. They allow the Pokemon to rebuild its shell while protecting others from the radiation emanating from the Pokemon.]]

Courting and Childrearing

Though Roggenrola are capable of breeding shortly before evolution, it is not often seen outside of captivity. When female Boldore and Gigalith are ready to mate, they send out low frequency sounds in order to attract suitors. Once suitors show up, they examine them for armor thickness and song quality before picking one to mate with.

Once mating is completed, the parents will use caverns to head over to a birthing cave, such as Wellspring Cave, to lay their eggs. The parents will guard them during the week it takes for them to hatch, staying only to teach their children basic sound creation skills before leaving. This is more a pathology of wild Roggenrola culture, as captive members of this line have no problems making more lasting bonds with their children, fellow teammates, and Trainers. The Roggenrola spend time inside their birth cave until they evolve into Boldore, at which point they travel through caverns back to the cave where they were conceived.

Social Structure

Like Golduck, Roggenrola are Pokemon that are mainly solitary, but have no problems interacting with others. In the wild, they mainly spend time alone or in groups of two except when there happens to be a particularly large source of water that causes them to converge, or when they’re mating or migrating. They are also known to associate with members of the Geodude Line and Carbink in places where their ranges overlap, such as the Alola region, in order to figure out who has the toughest outer shell.

In Human Culture

Due to the physical toughness of Roggenrola and its evolutions, the Unovan version of a popular idiom is, "between a Roggenrola and a hard place" to represent two equally tough choices. Gigalith, along with Golems and Golurk are also commonly used in media as guardians for temples, remaining still until approached. In recent times, a terrorist cell attempted to use a group of Roggenrola to create a massive death ray powered by their Flash Cannon techniques, but this attempt was thwarted due to the efforts of three young trainers and one lone Roggenrola, whose identities remain unknown as of this writing.

Boldore crystal can be used as an energy source, though it has a tendency to be unstable. Gigalith in particular are known for being beasts of burden, being a common sight at construction sites and mines working alongside Pokémon such as Copperajah and Coalossal.
