Gengar

Gengar is the first villain of the season. As a Gastly, he hypnotized Skorupi, Bagon, and Houndour to join an alliance with him, and was going to force Eevee to join, but hits Forretress on accident. This leads to his ultimate elimination in "Pokefight". He returned briefly in Shelter-Pelter to get revenge on Skorupi/Drapion for being the only remaining member of his ex-alliance in the game.
