The Cosmic Leaf is a transportation device used to travel between Absoverses.
It is extremely small compared to Absoverses, in order to travel from one to another, it must achieve extremely fast speeds proportional to its size. It achieves this through its shape and tail.
The tail flails very quickly and effectively, it runs on a hidden source of energy that comes from the outside.
Along with this tail, the Cosmic Leaf occasionally teleports ahead of itself, this decreases the wait time drastically and increases speed.
