it looks kinda like an onion and kind of like a rocket if you squint. I'm just confused.
Celesteela is likely based on Princess Kaguya from The Tale of the Bamboo Cutter: its body resembles bamboo shoots, its arms resemble cut bamboo trunks, and overall it resembles a mixture of elements of a space shuttle and a depiction of Princess Kaguya as a woman with long hair wearing a multilayered kimono. Its body may also incorporate similarities to the spacecraft SELENE (nicknamed "Kaguya" in Japan), which orbited the Moon between 2007 and 2009. The combination of bamboo and spacecraft elements may also reference bamboo rockets.
There's not much more to add other than that
