Grimmsnarl

Grimmsnarl is a green-skinned, humanoid Pokémon with most of its body covered in dark blue hair, except part of its face, its abdomen, its feet and a small red patch on its chest. Like its pre-evolutions, Grimmsnarl has large crescent-shaped ears with red insides, albeit they are longer on this form. Its long, sharp nose points upward and has a single long red nostril. It has a blue tongue and six teeth protuding from its mouth, the front four of which are flat, two on each jaw, while its upper jaw also has one sharp fang on each side. It has white eyes with red irises and black pupils, and grey eyelids. Its face ends in a small pointy chin.

Grimmsnarl's both hands and feet have three pointed digits each. Most of its long hair wraps around its body, except for a lock on each side of its face, a few spikes raised on its shoulders and some locks hanging from behind its legs resembling a cape. While being bulkier than its pre-evolutions, Grimmsnarl is more slender than it appears to be, with its hair giving the appearance of a muscular body.

While in its Gigantamax form, it becomes much taller and all of its body except its face and chest mark is covered in hair. Its limbs become longer, and its hair now makes up its hands and feet, each with three and two digits respectively. Its eyes are red with white pupils, and the hair from around its neck and shoulders are raised in a pointy collar-like shape surrounding its head as the two longer rear locks join in a single spike waving above the head.

Grimmsnarl's hair works like muscle fibers and helps enhance its strength. Grimmsnarl is able to move its hair, and uses them to ensnare opponents in a tentacle-like fashion. When in Gigantamax form, it creates a powerful drill with its leg hair. Grimmsnarl is a male-only species, but can be seen as a counterpart to the female-only Hatterene.

Grimmsnarl and its pre-evolved form Morgrem are the only known Pokémon capable of using the move False Surrender. In addition, Grimmsnarl is the only Pokémon capable of using the move Spirit Break, and the exclusive G-Max Move G-Max Snooze.
