My friend and I made some variant forms! She designed Roggenrola and Boldore :D
#524 Roggenrola: It has a jolly disposition, bouncing around caves using its psychic energy. Its hexagonal ear is sensitive to sound which fuels its psychic power. When it releases this stored energy, it makes a pleasant ringing sound.
#525 Boldore: Its stored energy has sharpened the crystals on its head, enhancing its psychic power. The cavities in its limbs can shoot powerful sonic waves, which can leave a high-pitched ringing in its victim’s ears.
#526 Gigalith: This Pokemon is usually found in hidden, meditative caves. Whenever it takes a step, it makes a low-pitched, bell-like sound. Under the night sky, it uses the power of the cosmos to release psychic waves capable of shattering mountains.
