|“||Should you feel yourself attacked by a sudden chill, it is evidence of an approaching Gengar. There is no escaping it. Give up.||„|
|~ The Pokédex in Pokémon Sun on Gengar.|
Gengar, also known as the Shadow Pokémon, is a dual Ghost/Poison-type Pokémon introduced in the first generation. It is the final evolution of the Gastly line, evolving from Haunter when traded.
Gengar has a roundish body covered in dark purple fur. It has short arms and legs with three digits on each, a stubby tail, and two pointed ears. Its face consists of two pink eyes and a wide mouth that is usually curled in a wicked grin.
In its Mega Evolution form, Gengar's lower body sinks into the ground with its arms, ears, and tail expanded in size. The fur on its arms, tail, and down its back is sharper and spikier. A third oval, yellow, and unblinking eye appears on its forehead.
In its Gigantamax form, Gengar's lower body again sinks into the ground, with its tail and arms protruding through the floor. Its eyes are white with yellow scleras. Its mouth becomes a gaping maw that tunnels down its throat with a long tongue sticking out.
Pokémon Mystery Dungeon
Pokémon Mystery Dungeon: Rescue Team/Pokémon Mystery Dungeon: Rescue Team DX
Gengar is the main antagonist of the games and their remake. He is the leader of Team Meanies and the boss of Ekans and Madicham. While other rescue teams profit over teamwork to save the day, Team Meanies use profit and status as a team to gain wealth and power, while Gengar plans to one day achieve world domination.
Originally, Gengar was a human with greedy desires. Trespassing into a sacred dungeon full of rare Pokémon, he attempted to grab a tail from a Ninetales. The Ninetales cursed the human, but his Gardevoir took the curse on behalf of her master. While the human cowardly fled, he transformed into a Gengar.
Throughout the game, Gengar and his rookies torment the player and their partner through their journeys, starting a bitter rivalry between the player's team and Team Meanies. Gengar even attempts to manipulate Caterpie to join their team by rescuing Metapod from the Sinister Woods, but the player defeats them and rescues Metapod.
Later, Gengar eavesdrops on the player, partner, and Xatu at the Hill of the Ancients discussing the Ninetales legend. He would forsake this the following day by spreading rumors upon the Pokémon Square residents that the player was the human in the legend, making them responsible for the natural disasters threatening the world, sending them and the partner out of town. However, after traveling to Mt. Freeze to hear Ninetales tell the player that they were not the human from the legend, they return to Pokémon Square to confront Gengar's lies. He tries to protect his rumors with a lack of the player's evidence, only for Pelipper to deliver newspapers stating the player's innocence based on Team A.C.T. witnessing Ninetales telling the truth. Enraged by Gengar's trickery, the Pokémon angrily run Team Meanies out of Pokémon Square.
Following Blastoise, Octillery, and Golem's defeat in the Magma Cavern, Gengar shows up and mocks the rescue teams that they have no chance of rescuing Team A.C.T. from Groudon. His words spread fear until the partner encourages everyone to not give up. Gengar angrily walks off and attempts to hack his way into the player's dream following their triumphant over Groudon. Gengar uses Dream Eater to expose the player for who they are, only for Gardevoir's light to stop him. She tells him that even with all the evil actions he committed, she always forgave him as he was her master. Heartbroken, Gengar tearfully leaves the player's dream.
Remorseful for his actions, Gengar helps the player and their partner behind the scenes when they reach Sky Tower to stop the falling star, first by helping Alakazam and Xatu create the Teleport Gem to teleport the party to the Sky Tower. After the player convinces Rayquaza to destroy the meteor, they and their partner are seemingly killed by the explosion. Gengar saves them by grabbing their spirits and dragging them down to the surface level under the pretense of taking them to the underworld, getting lost, and ditching them.
During the post-game, after the player clears the Stormy Sea and rescues Medicham from the Wish Cave, Gengar asks the player to escort him to Mt. Freeze so he could atone for his actions. Meeting Ninetales, she reveals it was his own selfish desires that cursed himself into a Pokémon. She gives them the 9-Tail Crest and directs him to the Murky Cave where he might be able to save Gardevoir.
At the end of the Murky Cave, Gengar and the player meet the "judge of darkness" who evaluates Gengar for his sins. After rendering his judgment, the judge states it impossible to lift Gardevoir's curse and leaves. Desperate, Gengar breaks the seal immobilizing him and beckons for Gardevoir's life. He admits to abandoning Gardevoir to be cursed and only through visiting the player's dreams did he discover that she always forgave him. Suddenly, the curse is broken and Gardevoir's physical form is released, with Ninetales appearing to say that gratitude was the true key to break the curse. She tells him that Gardevoir's memory will be erased, but Gengar admits Gardevoir being freed from her curse was enough for him.
Once they arrive back at the player's team base, Gengar awards the player with a Mobile Scarf. Before departing, an amnesiac Gardevoir asks for Gengar's name, to which he introduces himself to her.
