Presume he had just ate a power pellet, of course.
Followup matchups for your consideration:
- Slimer, from “Ghostbusters”
- Sadako, from “The Ring”
- Freddy Krueger, from “Nightmare on Elm Street”
- The clown from “It”
- A ring wraith from “Lord of the Rings”
Freddy feels more ghosty or at least vengeful spirity (which really is just deluxe ghost imo) to me considering he was a dude who died and lacks physical form most of the time.
Sadako is described as having the appearance of a Yurei, which is analguous to a ghost in western culture. If your only condition for Pac chomping is “can be reasonably described as a ghost” then she’s deffo there.

It and Ring Wraiths are admittedly further down the occult scale but when I posted I figured heck, lets see what arguments folks got for 'em.
Yeah, but Freddy can kill people. Most ghosts can barely move things. Just a little slime and some rattling chains.
