When PRIMEAPE beats its rivals, it wins the right to wear the Jungle Crown, evolving it to the noble EMPIRILLA, much stronger and more intelligent.
Empirilla is a large, bipedal monkey Pokémon. It has brown, furry hair all over its body, including a dark ruff around its neck. It has pointed ears and a pig-like snout. Its tail is long and curly. It has gold ornamentation on its body: golden cuffs on its wrists and a golden crown on its head. It has tusks protruding from its lower lip, one of which is capped in gold.
Female Empirilla have a jewel on their crown.
Empirilla, in addition to their mighty physical strength, have a much greater degree of intelligence and control than their pre-evolutionary stages. When it flies into a berserk rage, however, it is unstoppable.
Empirilla have gained a sense of nobility and leadership upon evolution, and their crown compels other Pokémon to follow in their lead.
