Well, people once said in the past it'd be impossible to make a proper Gengar headhack but I went ahead and gave it a try anyway. I tried with a traditional Gengar and saw how much cool it looked.
Then I tried the Pokken Gengar version with KM Bowser's body and the results are above: fantastic! It doesn't even look weird or anything, it looks great, at least for me!
And of course I gave him a chunky body to boot since that's how I'd imagine an anthro Gengar, just like those I see on fanarts out there.
I'll be using this fella for commissions, requests and personal art. Enjoy! π
Edit: I've updated his look a bit. Now he looks really good! π
Edit 2: Another fix thanks to a suggestion from a friend of a Discord server I'm in.
