Gengar is a dark purple, bipedal Pokémon with a roundish body. It has red eyes and a wide mouth that is usually curled into a sinister grin. Multiple spikes cover its back, and it has large pointed ears. Its arms and legs are short with three digits on both its hands and feet. It also has a stubby tail.
As Mega Gengar, a portion of its body sinks into the ground. The lower portions turn a more reddish purple, and a third eye appears on its forehead. This new unblinking eye is oval and yellow and allows it to see into other dimensions.[1] The spikes on Mega Gengar's back are more numerous and pointed. Additionally, spikes appear on its hands and tail. Its ears are now considerably longer and project backward.
Gengar has the ability to hide perfectly in the shadow of any object, granting it exceptional stealth. However, Gengar's body acts as a heat sink; its presence cools the temperature of the surrounding area by nearly 10°F, because it absorbs the warmth. In addition, Gengar possesses the ability to fly through the air, as demonstrated in the anime.
Gengar is very mischievous, and at times, malicious. It enjoys playing practical jokes and casting curses, such as pretending to be one's shadow, then behaving erratically. When the quarry notices, the Gengar takes delight in its victim's terror. However, Gengar has been known to be loyal to a Trainer who treats it well. Gengar lives in shadows of rooms, caves, and dark places where shadows form. It is especially fond of urban areas such as cities and back alleys, but only during the night.
Ash first saw a Gengar in person in Lavender Town in The Tower of Terror while searching for a Ghost-type Pokémon to fight Sabrina with. Due to a close call, Ash got to spend some unexpected time with the ghostly trio, Gastly, Haunter, and Gengar. It, along with Haunter, seemed to have a fondness for Japanese stand-up, and attempt to (unsuccessfully) amuse Ash by acting as a pair of performers. It reappeared in a flashback in the following episode.
Gengar first appeared under the ownership of a Team Rocket Grunt in Holy Moltres where it was used to battle Blaine's Arcanine and Rapidash and almost attacked Red.
In Pokémon Adventures, Agatha has two Gengar on her team, and many in her Ghost-type army. Her first one and her Ghost army first appeared in Lapras Lazily. One of them was used to attack Blue and Koga from the shadows, draining the latter's life force as it possessed his shadow. Eventually, it was taken down when Koga used the tail that the old woman's Arbok bit off his own to distract it long enough for Blue's Porygon to deal the finishing blow.
Another Gengar was seen at the beginning of the FireRed and LeafGreen saga in Volume 23. It was used by a kid from Pallet Town in an attempt to capture a Nidorino, thus replicating the opening sequence of the Generation I video games (and their remakes).
In the Pokémon Gold & Silver: The Golden Boys manga

Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team: Gengar is the leader of Team Meanies. While often accompanied by Ekans and Medicham, Gengar will often act alone and spends much of the game causing trouble, even convincing the village to exile the hero, blaming him or her for the natural disasters. However, it is later revealed that he is the cursed human.

Origin
It seems to be simply based on general cartoonish ghosts, cats, or the Cheshire Cat and possibly on a distorted shadow of a human being like shadow people.
Name origin
Gengar and Gangar are possibly a shortening of doppelgänger, a double of a person, which is fitting for a Pokémon with a habit of pretending to be a person's shadow. The kanji 幻 maboroshi can also be read as gen and is used in words meaning phantom or illusion. There is also a striking pronunciation similarity to the Danish word genganger, a term for ghosts found in Scandinavian folklore.
