Dr. Yung

"Remember, I'm also able to gain access to the Oak Research Laboratory Network, which as you are too aware of, gives me the power to infiltrate Pokémon databases, vast quantities of vital information located on every corner of the planet, enabling me to acquire all existing Pokémon data! And to show my gratitude, I will allow you to witness the birth of the ultimate Pokémon: a Pokémon with unlimited potential power, the moment when the world's strongest Mirage Pokémon WILL BE MINE!!"

- Dr. Yung (under his Mirage Master persona) revealing his true plot to use his Mirage System to destroy all Pokémon around the world.

Dr. Yung, also known as the "Mirage Master", is the hidden main antagonist of the 2006 Pokémon movie The Mastermind of Mirage Pokémon. He is a mad scientist who is bent on destroying Pokemon with his new Mirage system to take over the world.

He was voiced by Billy Regan.

Role
Yung was once a student at the Pokemon Institute, but he was expelled because his experiments were considered cruel to the Pokemon. This left him bitter, and he wanted revenge.

Yung invented the Mirage Pokemon system, creating powerful Mirage Pokemon who can use any attack, easily beating Misty in a Pokemon battle. Before Ash could battle Dr. Yung, he and Professor Oak was captured by the Mirage Master.

Dr. Yung was in fact the Mirage Master, as he was using a hologram so both could be seen at the same time. As the Mirage Master, he tortured Professor Oak to gain the password to Oak's laboratory database. Although Oak resisted the torture, Mirage Master had his Mirage Pokemon capture Pikachu and attempted to scan its memories for data, causing it great pain and forcing Oak to give up the password. With this access and his ability to hack Pokemon centers, Dr. Yung began forming perfect Pokemon free of any flaws which he despised.

He completed his perfect Pokemon, a Mirage Mewtwo, just as Ash, and later Misty and May, arrived to confront him. He attempted to kill Professor Oak, who defended himself with a Dragonite, and Mirage Master deployed missiles to create a larger area for his Mirage Pokemon so Mirage Mewtwo could be unleashed upon the world. He created a Mirage Entei, Zapdos, and Articuno to fight alongide Mirage Mewtwo for this.

Professor Oak eventually deduced Mirage Master's true identity as Dr. Yung, who finally reveals himself to the heroes. Yung had become annoyed at a Mirage Mew appearing, whom he described as a flawed specimen. He then orders Mirage Mewtwo to battle Ash and the gang, and nearly killed Pikachu before Mirage Mew entered the battle to stop Mirage Mewtwo, and Pikachu used Volt Tackle to destroy Mirage Mewtwo and the entire Mirage System, setting his lab on fire. Unfortunately, this destroyed Mirage Mew as well.

With Dr. Yung's plans ruined, Professor Oak demands him to surrender himself, but Yung refuses, saying that he still has much more work to do, and instead walks into his burning lab, which later crumbled down to pieces. Yung was never seen again following this, and was not yet found by police or firefighters during the ending scene. It is presumed that he was crumbled to death.
