Stakataka

Stakataka appeared in 2017 video game called Pokémon Ultra Sun & Ultra Moon. Stakataka is a Rampart Pokémon. It's thought that Stakataka, one of the mysterious Ultra Beast, is made up of several life-forms stacked on top of one another. This creature resembles a stone wall covered with markings that look like blue eyes.

While Stakataka may appear to be made up of stones stacked atop one another, apparently each “stone” is in fact a separate life-form, and this UB is made up of an assemblage of these life-forms.
