Finally, suggestions are up! I've been waiting a long time for this moment. I have one evolution line to show you. To expedite the submission process, I'll put the picture of the evolution line first, since it's quite big and clearly shows all three. Excuse the horrible quality.

Crisnite (CRIStal + NITE, both are mutations of the respective words)
STALACTITE Pokemon
Height - 2'1'', Weight - 46 lbs.
Rock/Dark
Description: See above.
Data:
"When CRISNITE grow to adult size, they fall from the cave ceiling using their spikes as legs."
"The crystal is actually a part of their body, and is very reflective. It causes headaches in humans."
Evolution: Evolves into STALNEYE at level 24, then again into DARKRYST at level 45.
Gender Ratio/Differences: 50/50 for both genders. The females have a lighter colored crystal, as opposed to the darker males.
Ability: Clear Body or Rock Head.
Dream World: Intimidate.
Base Stats:
HP - 35
Attack - 45
Defense - 50
Sp. Attack - 30
Sp. Defense - 40
Speed - 10
Egg Group: Monster/Mineral.
Habitat: Crisnite is the only member of the line that can appear in the wild, and even then, it is slightly rare, and can only be found in deep, dark caverns. They often give themselves away, as their crystal takes in any trace of light. They look like luminescent ceiling spikes to the untrained eye.
