Also know as "Horrid Mega Gengar" or "The Gengar Nightmare" or "Gengar's Shadow"
This is my Halloween Deviation this year. I had this idea when I first saw the leaked Mega Gengar. I loved it, but thought could have some more "demonicness" SO! I decided to make this: Dreaded Mega Gengar for my Halloween Deviation this year! However there's more. I made up a Fake Pokedex entry for it:
Dreaded Mega Gengar
It is said to be the shadow of Mega Gengar. It is said to be the most horrifying Pokemon, even scaring normal Gengars and Mega Gengars.
