Gengar (Mystery Dungeon)

Gengar, along with Medicham and Ekans, is a part of Team Meanies. When the Whiscash Elder sent the teams to find Pichu's brother, Pikachu, Team Meanies went to Kecleon Brothers' store and bought everything. Soon after, the team attacked Team Go-Getters and snatched their berries, then took off to the mission, claiming such work needs to be left to professionals. Pichu joined them, but Gengar lied to him that he heard Pikachu and sealed the tunnel (in which Pichu was being in) with a rock, using Confusion. However, Gengar, as well as the rest of the team, got attacked by the rampaging Skarmory and lost the battle, but blames the loss on his companions. Team Go-Getters came and Squirtle offered Gengar the berry, which most of them were eaten by Ekans, claiming Pokémon should stick together. Seeing the wisdom in those words, Gengar ate the berry and went away with his team off.
