Stakataka is an Ultra Beast composed of many dark gray, stone lifeforms stacked together to form a four-sided tower with a spindly leg on each corner. The stones that form the legs and the top corners are slightly darker. When at rest, its legs fit into the corners of the structure. Its lighter gray stones have glowing blue lines on their sides, which are visible along its edges and underside. Each stone square has a black underside with a circular, glowing blue eye in the center. These eyes will turn red whenever angered or fighting. According to Phyco, a single Stakataka consists of almost 150 individual lifeforms. As seen in the anime, Stakataka hates having anything on top of itself and will violently try to shake the object off. However, if someone can resist the shaking and successfully ride it, then it will calm down and they'll gain Stakataka's respect. (Source: Bulbagarden.net, CC BY-NC-SA)
