Mirage Pokémon (Japanese: ミラージュポケモン) are holographic Pokémon, first seen in the anime special The Mastermind of Mirage Pokémon. They were created by Dr. Yung, the Pokémon scientist who invented the Pokémon Mirage System, a machine that generates Pokémon holograms. The Mirage System was initially created for the purpose of creating a new species of "perfect" Pokémon. It was later used by Dr. Yung in an attempt to get revenge on the members of the Pokémon Institute who expelled him after he presented them with the Mirage System, claiming that it was a cruel and disrespectful way to treat Pokémon.
The Mirage System is capable of creating virtually any Pokémon assuming data on those Pokémon has been acquired. These Pokémon essentially have no weaknesses and are invulnerable to attacks from normal Pokémon. They are able to know and use any move, even ones they would naturally be unable to learn. This is comparable to a Pokémon in the main series games which is hacked, such as a Mewtwo with Quick Attack, a Beautifly with Aeroblast, or a Walrein with Meteor Mash. Pokémon that were created during the events in The Mastermind of Mirage Pokémon include Machoke, Machamp, Magnemite, Omastar, Kabutops, two Aerodactyl, Articuno, Zapdos, Mewtwo, Mew, Ursaring, Houndoom, Entei, Mightyena, Aggron, Armaldo, and Absol.
Although the main area that the Mirage Pokémon can travel is held inside Dr. Yung's laboratory, it can be expanded through the use of holographic generators that are launched from the laboratory in a fashion similar to that of missiles. This expanded Mirage System allows the Mirage Pokémon to travel outside the laboratory and battle in different environments. The extent of this expanded area is unlimited.
When the Mirage Pokémon are not in use they can be "stored" in the mirage system until they are needed. This is similar to how real Pokémon are kept in Poké Balls. A trait that is unique to the Mirage Pokémon is the ability to use the data of other Mirage Pokémon to give them an edge in battle. This ability was used by the Mirage Mewtwo when it battled Ash and his friends. During the time that this ability was being used, it was revealed that any mirage Pokémon whose data is being used are still fully conscious, this became evident when the Mirage Mew acted out and stopped Mewtwo from attacking. However it should be noted that the only reason Mew was able to do so is because it had the free will that the other Mirage Pokémon lacked.

- Mew was the only holographic Pokémon who had a heart and who wasn't able to be controlled.
- "Mirage Pokémon" also refers to legendary Pokémon and Mew in particular, although this is mainly a coincidence. In Japanese, the term used for legendary Pokémon is まぼろしの ポケモン illusory Pokémon, using the Japanese word "maboroshi"; meanwhile, Yung's mirages are ミラージュポケモン mirage Pokémon, which uses the English word "mirage."
- Even though the Mirage Pokémon are often described as holograms, both they and their attacks are made of actual physical matter rather than light.
