Eiscue is a medium-sized, penguin-like Pokémon with a large ice cube on its head. This ice cube is a light blue, with specks of white seen dotting the surface of it. Two oval-shaped eyes and a beak are seen on the front of the cube. It also has a long, antennae-like hair sticking out of the cube. Eiscue's body is black and white with light blue accents around its belly. It has two flippers and yellow feet, with three toes on each. Its true face within the ice is colored light blue with two white eyes, black eyebrows and a white beak, and has a worried expression to it.
Eiscue comes from extremely cold areas. It can produce cold air from inside its head to create ice to protect its head from heat. The ice, however, is not very durable, as a strong blow can shatter it, after which it goes on to create new ice. Eiscue is easygoing by nature. It is a poor swimmer, and is often seen aimlessly floating in the ocean with just its ice-covered head floating on the surface, occasionally washing up on distant shores. It never panics or gets upset whenever it ends up in a new land, instead continuing due to its ability to adapt. The ice on Eiscue's head has a mild salty taste, presumed to be caused by it having floated in the oceans. When the weather is hot, groups of Eiscue will cool each other down by pressing their ice cube heads together. Eiscue's hair is connected to the surface of its brain, which then chills the air around it when it has something on its mind. Eiscue also uses its hair to catch prey in the sea, by forming ice balls at the tip and dipping it into the water like a fishing line.
The ice that was covering this Eiscue’s face has shattered. Eiscue emits cold air from the tip of its hair to protect its head, which is sensitive to heat.
