Yeah, this is lookin' real nice

I'm leaning Gastly as my first, tentatively Duskull. A mother goes to check on her kid in the middle of the night. She thought she heard crying. But the nursery is silent when she gets there. Just a pair of glowing eyes floating over the crib. That kind of thing! 

If I don't go hard Ghost, I could do 'amorphous' Pokemon. That'd include Slugma who's a good boy.  

Speaking of ghosts and tech shenanigans, Rotom's poltergeisting would suit that pretty well, haha
