Celesteela

Celesteela is a large, humanoid Pokémon that is mainly green, with a bodily construction that closely resembles that of a bamboo shoot. It has a horn, that resembles a drill bit that appears to be atop of a structure that is similar to a hat with two small green spots. There is another structure that stems from the "hat" that resembles hair. The lower half of its head is small, with a tiny mouth. Its long neck is divided into three segments; each one of the segments resembles a long, individual neck. Its lower body consists of a structure that is similar to a dress colored in different shades of green. Below the dress, there is what appears to be bamboo stalks. Its huge, disembodied arms resemble stalks of bamboo, with similar projections surrounding a larger opening.

According to the Aether Foundation, its most distinctive feature is the energy that it stores within itself: a flammable gas that it can shoot from its two huge arms. This is mostly used to propel itself in flight and for battle, but it is thought to have sufficient power and lift to even fly into space. Celesteela's rocket thrust is powerful enough to destroy an entire bamboo forest. Despite being a Steel type, Celesteela's body is plantlike and can absorb nutrients from the soil. Celesteela is known to have a long lifespan, as one was buried in Alola for over 200 years. Celesteela originates from the Ultra Crater dimension in Ultra Space.
