Celesteela is a giant anthropomorphic Steel/Flying Pokémon, and one of the legendary Ultra Beasts. She has a curvy and somewhat chubby female body, with huge breasts, a fat belly, and thick hips. She is codenamed "UB-04 Blaster".
Her most distinctive feature is the energy that she stores within herself, a flammable gas that she can shoot from her two huge arms and take off like a rocket. Celesteela is friendly and benign, though unintentionally destructive due to her sheer power and size.
