"With the hair wrapped around its body helping to enhance its muscles, this Pokémon can overwhelm even Machamp. Its hairs work like muscle fibers. When its hairs unfurl, they latch on to opponents, ensnaring them as tentacles would."
This Pokémon evolved from a Morgrem which evolved from a Impidimp.
Grimmsnarl is an Dark/Fairy Pokémon owned by Lexi. He was first introduced as an Impidimp in GF045, before evolving into Morgrem in GF061 and finally into Grimmsnarl in hope~ The Crowned Tundra.
Grimmsnarl first appeared as an Impidimp in GF045 when a group of Grimmsnarl and Hatterene were feuding over their habitats in Glimwood Tangle. Impidimp and his friend Hatenna would sneak off from the group and play together, being unhappy that their species was fighting. When Lexi and her friends arrived, their feuding was causing the rest of the forests inhabitants to flee or become enraged or scared. After figuring out that the squabling was due to Impidimp species thriving off negative energy while Hatenna species thrive on calm enviroments, the group shows the Impidimp species about being mischevious with each other, rather than with Hatenna. The squabling subsided, but Hatenna and Impidimp were still considered to be outcasts because of this. Sensing their determination, Lexi decided to capture both in order to free them of their families prejudices.
As an Impidimp, he was incredibly mischievious Pokémon. He often played pranks on other people and Pokémon, which was always taken badly. If he scared people, he took it as a win. As a Morgrem, he became a lot more distant and cold, seeming very emotionally detatched and defiant. However, as a Grimmsnarl, he took traits from both personalities with him, and he also became a lot more mature and focused, despite keeping his cold demeanour with a hint of mischief.
Grimmsnarl has the ability of having his hair work as if they're muscle fibers.
