Leukoon devours potential threats with its huge mouth to restore nature to its previous beauty. It has a void within its body that it uses to consume threats to the forests it lives in.

Pokédex entry
Scientists call Leukoon the immune system of nature. It is able to engulf any threat to its habitat using its massive, void-like maw.
Until the introduction of Hisuian Zorua and Zoroark, no other Pokémon has had the same type combination as Leukoon.
At 140, Leukoon has the highest Defense of all non-legendary Pokémon in the Sage Pokédex.
Leukoon was originally intended to evolve from Erycoon, but was later turned into a counterpart to it instead.
Leukoon's first concept art was of a bullfrog rather than a raccoon.
Design origin[]
Leukoon is based on white blood cells, also called leukocytes. White blood cells are an essential part of the body's immune system, as they engulf and kill bacteria, fungi and parasites, similar to how Leukoon protects its home by devouring potential threats. Its physical appearance is based on a raccoon.
Name origin[]
Leukoon's name is a combination of leukocyte and raccoon.
