Stickut is a large beetle Pokémon with a light brown belly, two dark brown hands, with brownish-yellow arms, three claws on each hand and a spike protruding from each wrist and two brownish-yellow legs. It has a large brownish-yellow horn on its head, with a barb on each curved end. A darker brown shell covers its back, with two leaves similar to wings. It also has two leaves for what seem to be ears.
Despite their large size, they can still move at a fast speed. Their hard outer shell also defends it from stronger attacks. It uses its horn to fight against opponents, which appears to be very effective.
Stickut are aggressive towards others. Male Stickut fight one another to win over a female. They take massive pride in their large horns.
Stickut live in deep, forested areas. They nest in each of the trees in the forest, but only one is nested per tree.
Only one Stickut inhabits each tree in the forest. If another Stickut appears, they'll fight to toss their opponent off. The victor stays while the loser seeks a new tree.
