Ghost Shy Guys?

[CeeY]

Then again, how are the rules on "Characters that aren't from a game, but are a slight variation of a real character that already has a countless amount of versions"?

Um... That would be a custom character, which is a no-no. Still, this is a good quality sheet, so... maybe try submitting this to MFGG.

No not MFGG, this deserves to be on TSR! Shyguy Grey, make a submission topic, and submit this to TSR, it's great!
