Age: 200 million years Gender: Male Height: 500m Features: His entire body is surrounded by unique dark blue bone-like structures. There is a red glass-like membrane on his chest, inside of which is a white circular core. On his head, there is also a red glass-like membrane between long, thick arrow-shaped bones (the face looks somewhat like a fan). White eyes are visible within. There are bone-like tentacles on his back that look like wings. The tail appears to have transparent red muscle inside, with a red gem at the tip. He wears a tangerine necklace around his neck. (Given the lack of legs, he seems to float in the air.) He has four arms. The slender arms have five long bone fingers (originally three, but increased to five). (Description) A Pokémon with a bizarre appearance, its entire body composed of nothing but dark blue bone-like structures. While it has an appearance alien to existing Pokémon, the origin of this Pokémon is not explained in the story. The Pokédex only states that it appeared from a meteorite 20,000 years ago. It is the first Poison-type Legendary Pokémon and remains the only Poison-type Legendary to date. The core in its chest absorbs energy rising from the earth of the Galar region to function, or it occasionally emerges outside. (Maternal and obsessive personality)

Height: 1000m #This is the form of Eternatus after Gigantamaxing# The body is red with twinkling white stars, made of a lava-like material, and shaped like a white-striped snake. The face is a hand. The palm in the center changes from red to white. There are 5 bones in the center with a core in the middle. The fingers are made of bone. Massive wing-bone-like tentacles are attached. There is a red mist ring-like structure above the tail. It has two massive arms. (The body is twisted, resembling a whirlpool or a "mosquito coil.") The body can be unfurled, though it feels a bit ticklish. A form overloaded by absorbing the energy of the entire Galar region (details are unknown). (Description) Eternatus's exclusive Dynamax form and its original true form. It boasts the largest size among all Pokémon in history. In its Eternamax form, it changes into a shape like a giant hand reaching down from the sky. The fingertips are structured to open, and there are five protrusions on the palm. (Infinite power is released from the enlarged core, distorting the surrounding space-time.)
