Psychic Bryce has a gengar in Pokemon platinum.
To get a Gengar, you must trade a Haunter and it will then evolve into a Gengar.
yes after you beat the game and gengar asks to save gardevoir you go to a dungeon with lots of ghost Pokemon and if you evolve a ghastly or haunter it can become gengar and while your in the ghost Pokemon dungeon gengar is on your team
You find ghost Pokemon and rotom. And if you have any Pokemon game in your gameboy slot you can also find gengar.
you cant find gengar if you not have steal trainers Pokemon cheat
gengar can defeat any Pokemon same with any other Pokemon
Gengar is a Ghost-Poison type.

It evolves into Haunter at level 25, and then into Gengar by trading Haunter to another Pokemon game.
