Amaura is a quadruped, dinosaurian Pokémon that resembles a sauropod. It is light blue with a white underbelly. It has a long neck, a short, stubby tail, and a single white claw on each hind foot. Above each of its large, deep blue eyes is an iridescent, sail-like structure. Typically, the sails are yellow at the bottom and fade into pink toward the tips. On each side of its body is a dark blue crystal. Pokémon-Amie has demonstrated that its sails can change color with its mood and the crystals on its sides permanently remain at freezing temperatures.
Amaura is a calm Pokémon that lived over 100 million years ago. It lived in a cold land to avoid predators such as Tyrantrum. Despite its restoration, it is not expected to live long in the heat of current climates. As seen in the anime, it can create auroras.
Amaura is based on a young sauropod dinosaur. It bears a strong resemblance to Amargasaurus, which were speculated to have skin sail extensions on their vertebral spines. It also shares traits with various species of Diplodocoidea. The color-changing sails upon its head are also based on auroras, most likely aurora borealis due to it being Ice-type.
Amaura may be a contraction of Amargasaurus combined with aurora.
