As Lugia
Gengar was once a powerful Lugia, until the Whirl Islands caved in after intense oil drilling. This killed him, and his intense power was turned into a small Gastly. He had to work his ass off to gain enough power. Gengar still seems to long for his powerful past, and kept his pretention as Lugia.

Into Chateau
Gengar previously lived in a small studio apartment, but felt that it was not intimidating enough. He noticed that Old Chateau was empty, and helped himself in. Sure, he doesn't technically "own" it, but who would challenge him on it?

Froslass
For more information, see Gengar And Froslass, Hovering In A Tree. Gengar joined Twitter mainly to keep tabs on Froslass. He finally asked her out, and she reluctantly said yes. He fell insanely in love, and they showered each other in gifts. However, Froslass in the end was kidnapped, and Gengar fell into a state of drunk depression. His white wine was his only friend, until he met...

Shiny Banette
Gengar met a ShinyBanette, who he had a one night stand with. She then drugged him and stole some of his stuff. He tracked her back down, and they started a relationship, with loud sex. However, Shiny Banette seems to be a little shady, and he has had to bail her out of jail on several occasions. She also held an orgy during the events of Gengate and had sex with Misdreavus. She seems to be very very secretive as well.

Gengate

Dusclops and Drapion
Drapion needed to feel like he was good enough for Misdreavus, so Gengar decided to give him assistance, and offered to sent a Dusclops to kidnap Misdreavus. This appalled the two, and Drapion began to insult Gengar, and Gengar returned fire. However, once Drapion mentioned Froslass, Gengar went berzerk, and released Dusclops. Linoone saved both Drapion and Misdreavus, who then broke up with each other. Gengar tried to go for the rebound with Misdreavus, and failed.
