Gengar is a dark pink, bipedal Pokémon with a roundish body. It has red eyes and a wide mouth. Multiple spikes cover its back, and it has large pointed ears.
Gengar cannot be caught or be found in the wild on any of the maps. However, he can be seen as the 7th gym's leader Irie's pokemon of choice. If any player is seen with it, which they will not, it is use of a hacking tool, supposedly Cheat Engine. Luckily there has been a patch and the creator has disabled cheating for Gengar.
