Thaddeus revived Amaura from a fossil, along with Aurorus. Amaura, upon encountering the heroes, played with them, with Aurorus watching over it. Team Rocket was interested and stole Amaura, and then took off. Since Amaura gets sick when in warm weather (outside the lab), it emitted Aurora Borealis to let the heroes and Aurorus know where it is. The heroes found Amaura and rescued it from Team Rocket. After Aurorus had stabilized its temperature, Amaura was taken in a truck back to the lab.
None of Amaura's moves are known.
