Huh. Well, most of my players usually end up hating my DMPC's.
Not in the "Wow this guy is stealing the spotlight way", but more in the "Wow this guy is hilariously a jerkass". So they love to hate them.
Then I also had a sort of parole officer DMPC, which was funny because he was actually really nice to them and was just doing his job. They ended up killing him, and feeling really bad about it.
And then, most recently, I DMPC'd a werewolf character who had a string of hilarious critical misses and despite saving their asses half the time was viewed as the most incompetent character ever. I had him play with it and ended up as the buttmonkey- ambushes always targeted him, and I eventually started rolling d12s for his saving throws.
