Gwen. I HATE her. She's followed me in EVERY single game I've ever played. Just started a second cartridge recently, and she showed up in that village too.
And of course she always takes forever to leave too.
I forget whether he made it into any of my New Leaf towns, but Butch followed me from Animal Crossing into Animal Crossing: City Folk. I didn't initially like him in the Gamecube game since he seemed like a jerk, but I grew to like him. I was pretty happy to see him back in City Folk even though I never really got into City Folk.
I think Harry followed me from City Folk and into New Leaf. I wasn't too happy with that, as his design is kinda ugly and I wanted more variety.
Peggy the Pig ended up stalking me through every single AC I bought. ._.
Dear lord, I could never escape her but I despise her so much. Just. Ew.
When I was resetting starter towns to get Kabuki, she showed up five times.
FIVE.TIMES. ene
Wart Jr. was in my ACG game for a while and he was in my town when I first started ACNL. I was so happy. I'll never get rid of Wart Jr.! I don't think he followed me through each game, but I didn't play the other two games as much as I have ACNL and ACG.
Dizzy and Maple for me! They were both in my WW town and in my NL town - got them both through Campsite. Trying to get Dizzy for my 2nd town as my only repeat for my NL towns
Stinky followed me... it was definitely "emotionally annoying". He's probably my favorite jock villager, but I had to let him go (painfully) because I wanted to be able to get more of a variety.
