Ghosts are one of the rarest types of pokemon with only 54 in existence. A Pokémon with Ghost and Dark dual types is the only type combination to have no weaknesses. Ghost moves are super-effective against Psychic and Ghost types, but are not against Dark, Steel, and Normal types. Normal, Fighting, Poison, and Bug types also have little to no effect on Ghost Pokémon, while Ghost and Dark are super-effective.
Gastly is made up entirely of gas and can slip into any place it wants. A strong wind can dwindle away their bodies, so they often huddle together in groups to avoid this from happening. Haunter gains the ability to float through walls, and Gengar can become perfectly hidden in the shadow of any object. They all enjoy pranking people, and Gengar will often pretend to be the shadow of people to confuse them. Haunter and Gengar will both mess with the dreams of the sleeping as well.
Shuppets look like a cloth covered ball with the usual Ghost-type abilities. It often roams around cities at night where it feeds upon negative emotions such as grudges, envy, and vengefulness. If someone develops strong feelings of vengeance, Shuppet will appear in a swarm and line up underneath that person's home until the sun rises in the morning. Banette are doll-like Pokémon that are said to live in garbage dumps where they wander about in search of the person that threw them away. They also generate energy for laying strong curses by sticking pins into their own body like a voodoo doll.
Litwick are small floating candles that pretend to be guides for people and Pokémon, while really they are sucking out the life energy of them. Occasionally, a Lampent will work alongside a Litwick to lead victims into the Ghost World, but this is rare. Chandelure use their arms to hypnotize their opponents, and the fire from their candle is burning up the victim's spirit and not their own power.

Psychic Pokémon do not have many outright strengths, but they also do not have many weaknesses. In the first generation, Psychic types were incredibly powerful as there were no powerful Bug moves, which were its only weakness, and Ghost-type moves had no effect on Psychic types. Generation II fixed this by adding the Dark type and better Pokémon and moves for all types. The 114 Pokémon of this type are super-effective against Fighting and Poison types, but not very effective against Psychic and Steel types, and having no effect on Dark types. Fighting and Psychic Pokémon are not very effective against this type, but Bug, Ghost, and Dark types are super-effective against them.

Gothita always stares at Pokémon and Trainers intensely, but only they can see what they observe. They use their ribbon-like antennae to amplify their psychic powers. Gothorita use starlight as the source of their power and can arrange rocks the same way the stars are arranged. They control people and Pokémon with hypnosis and are even said to steal them away at night. Gothitelle have the ability to foresee the future by using stars and can see the lifespan of Trainers.
