I'm fond of a number of the Pig villagers; Agnes, Boris, Chops, Cobb, Gala, Hugh, Pancetti, and Rasher are all good by me, and the only one I'm really not fond of is Truffles.
Tough choice between Boris, Chops, Cobb, and Rasher.
I'm probably going to have to say Cobb because his green skin and yellow eyes, in combination with the Mad Scientist furniture he had in New Leaf, made me think of him as like a mad scientist who has maybe been affected by his experiments. I have him in New Leaf rather than New Horizons, so even though all of that's gone in New Horizons other than some bookshelves, I can still sort of roll with it and it doesn't really effect me any.
Chops came close and would probably be second since he's just a refined genetlemanly sort of villager and Smug is my favorite of the male personalities, plus his house in both New Leaf and New Horizons is really pleasant. I really like Rasher because his scars are a nice distinguishing feature, and I love the grin that he does, but I've never really liked his house in any of the games.
KEVIN! Kevin is my man. My bro. My close good friend. He is not only my starter jock, but my birthday buddy, and the first villager on my island to not only befriend me, but give me their special reaction. Kevin is the alpha and the omega, the king of all pigs. You gotta love him for his adorable little face and jock personality.
Spork is my boy! He was my first lazy villager, and I ended up getting attached to him despite having Erik’s Amiibo. He’d the perfect embodiment of the lazy personality, especially with the dirt floor in his starter house. Plus, look at him watching this lovely butterfly in his cute raincoat.
Agnes, Boris and Hugh are all favourites for me! For the purpose of this thread though I am going to say that Agnes is my favourite purely because she happens to be the one on my island.
