Rajang

Did you know Rajang is Gatr's favorite monster? I didn't feel like writing anything for this so have an excerpt from Monster Hunter 2 and the Monster Hunter Wikia.

Ultra-aggressive creature that is rarely sighted and seldom survived. Survivors report it exhibits a strange attack. The Rajang is said to be a loner, and this isolated life has made it difficult to pin down its territorial leanings.

Rajang is extremely violent, unrelenting and ultra-aggresive, and it's intensely territorial as well.

The Rajang's most notable attack is its ability to shoot electricity from its mouth, either as a blast or a beam. They're well known due to their combination of speed, aggression and power. They are also famed for their dramatic Rage Mode, in which much of the fur on their front body rises and becomes gold.
