I found a perfect monster for adding Bob Velseb into a Dungeons and Dragons game!
Tho if ya wanted to get even closer to an exact match with him losing the wings and tail, then you could make him a half-fiend, as fiends can produce offspring with other races including humans.
So you would have a half human half pie fiend who can shape shift between a human and demonic form. And he could lack a lot of the pie specific cooking magic that pie fiends often pick up over their long lifespans, but still be a very cooking obsessed dude with demonic abilities.
