The guardians of the Tree of Beginning
The Tree of Beginning (Japanese: 世界のはじまりの樹 Tree of World's Beginning or simply はじまりの樹 Tree of Beginning) is an anime-exclusive location and one of the settings of Lucario and the Mystery of Mew. It is located in the northern reaches of Kanto near the kingdom of Rota, beyond Pewter City and Mt. Moon.
It is a rock formation that appears to be a gigantic tree. The Tree of Beginning is actually a living organism made up of crystal that feeds on sunlight. It has a symbiotic connection with a Mew that lives within it. The Tree of Beginning is a pristine environment and it is home to many kinds of ancient Pokémon thought to be extinct. It has a "circulatory system" of sorts that distributes nutrients to the crystals throughout its body. It also has a complex antibody system that takes the form of Fossil Pokémon that attack humans and machines within it, as well as guardians in the form of the Legendary titans.
The crystals of the tree actually seem to extend far beyond the formation itself, emerging from the ground like roots throughout the surrounding areas Time flowers grow inside and around the Tree of Beginning.
Centuries ago, Sir Aaron sacrificed himself to transfer his aura power to Mew so it could restore peace to the land and save it from two raging Pokémon armies. In the present, Mew, when attacked by Kidd Summers's two Weavile, whose job was only to put a tracking device on it, teleported to the Tree of Beginning with Pikachu and Meowth due to injuries Pikachu receiving in the battle. Ash, Brock, May, Max, and Lucario set out to find Pikachu, since Mew had a history of taking toys from nearby Cameran Palace and never returning them. Kidd Summers also accompanied the group, working on behalf of Banks to uncover the secrets of the Tree of Beginning. Inside the Tree of Beginning, they were attacked by Regirock, Regice, and Registeel. Lucario fought them off but none of his attacks worked on the white blood cells, which ate Jessie, James, Brock, May, Max, Kidd, and Ash. They wouldn't swallow Lucario, however, due to not perceiving any Pokémon as a "threat".
Mew brought them all back to life, though unfortunately, this put the immune system into shock and doomed Tree of Beginning tree to die unless the same aura transfer with Mew was performed. Ash and Lucario transferred their power to Mew in order to restore the Tree to full health, Lucario finishing the process, sacrificing himself as Sir Aaron had done many years ago. The Tree of Beginning was restored to full health and the Legendary titans stopped attacking the humans.
Pokémon seen in the Tree of Beginning
The Tree of Beginning appears to be based on the Norse myths of Yggdrasil, the world tree.
