Elgyem is a small bipedal slightly humanoid Pokémon. Its round ovular head is quite large in comparison to its short body. It has teal skin and oval-shaped bright green eyes. Its forehead is quite large, with black Y-shaped markings in the center, and indents on either side of its head. It has a slightly rounded belly and two stubby feet. Its arms are long with three glowing yellow, red, and green finger-like dots at the tips. It uses these luminescent dots on its hands to communicate.
