Grimmian

The Grimmian is a Fan-Made Grimm in the Jester Mad Universe. During their juvenile state, they are as tall as Death Stalkers when the Grimmian is on all fours. When it's an adult, it can reach up to sizes of Goliaths. Berde Bazahka enjoys hunting juvenile Grimmians, but are largely hated to be encountered due to their incredible speed, strength, and aggression.

Berde's Journal
Name: Grimmian

''Height: 7 foot on all fours. Around 15 feet on hind legs''

Description

''Head is as large as my torso; around 3 ft. Large arms; armoured arms, back, and face. Red markings on plating. Small, but still powerful legs. Able to be used for sprinting quick and leaping tall distances. Some spiky hair on its back; explodes upward when enraged.''

Habitat

''Unknown. First spotted after my first year of my travels. Grimmians seem nomadic as I first spotted one in Atlas, then there are some even in Forever Fall or forests of Vale. Mostly seen alone. Behaviour with other Grimmians unknown, but seemingly a loner.''

Behaviour

''Ultra Aggressive. Once spotted by him from 30 meters, will immediately attack. Capable of brutality; killed a soldier when it was faking death.''

Adult Grimmian

''Can't defeat it. Much more powerful, faster, larger, and tougher than a normal Grimmian. Now has the ability to conduct electricity and breathe it out as a straight beam of electricity. Much smarter. The lucky part is that it's an utter loner and seems to be rather territorial albeit a bit nomadic. Smart, it can make tactical retreats when heavily damaged. I managed to injure it, but I was low on Aura. Before I could attempt to retreat, it retreated first.''

Description
Grimmian are masked Gorillas with armoured arms, head, and back. They have a large upper body; heavily muscular. While their legs are shorter and more skinny, it still packs a lot of power. It has spiky hair on its back and on its head, which stand up when enraged.

Adult Grimmians gain horns, their hairs are much more spiky, and have more plating on their chest and arms. Their chest armour resembles a heavily toned man of Greek musculature as seen on statues. They're able to surge red lightning through their arms, making them much more tougher and stronger.

Abilities
Grimmians are incredibly powerful Grimm. Even in Juvenile form, they can unearth large chunks of land and toss it with one hand. Their fists are incredibly fast and powerful, able to knock Huntsman incredibly far. Their fists are powerful enough to cause small quakes that can disorient foes. They are also incredibly smart and have some form of technique in their grace as they're capable of doing a form of donkey kick that moves them back, attacking foes keen on attacking their legs.

They're able to leap high and far with their powerful limbs. These limbs are even able to outpace a sports car, making him incredibly hard to escape from.

In their adult form, though unconfirmed, some scientists and Berde theorize it somehow develops a Lightning Generator inside of it, or that they consume electric eels to develop a gland inside of them meant to hold electricity. It's currently unknown how they do it, but the electricity they exude can deal heavy damage to both Huntsman and the environment alike, managing to bunge even mountains. They can also transfer this electricity into their arms, strengthening and toughening it. While their legs have gained armour,

Weakness
For all their incredible strengths, according to Berde, the biggest weakness is its legs. While able to leap far, when their footing is disrupted, it can make them more or less turtles attempting to get up. According to Berde, they can easily be cut with enough damage dealt to them, heavily decreasing their mobility.

Trivia

 * The normal form is based on most gorillas, while the adult form resembles the Rajang from Monster Hunter.
