Well, my favorite villager changes once in a while, but right now it is Rooney! <3
First of all, he is the most handsomest male in my opinion. But more importantly, I love the vibe he puts off. A lot of people like him because he has a very sporty. Well, that's not me. He gives off a "velvet-covered brick" vibe to me that I absolutely love. If you don't know what that means, it means that he is strong and protective of himself and his loved ones when hardship comes his way, but he is also loving when the people he cares about need it most. There aren't too many people that are like this, so it's nice having an Animal Crossing villager that gives you that "tough, but loving" vibe.
Deep down, I know that the "jock" personality fits him better than the "cranky" personality, since his house is more sporty than all of the jock villagers and is into boxing, but Rooney just wouldn't be the same to me if he was a jock. The cranky villagers are so loving, especially in NewLeaf and if he was a jock, he would just be tough, he wouldn't have the fatherly aspect of him that I also love so much.
I think we need a few cranky villagers that are a little sporty, since toughness and strength are very important things about them! And staying physically active helps maintain the whole "strong and protective" vibe about them! <3
Mine is Wolfgang. He was my first favourite ever and I love how mean he is at first and how he warms up to you after haha. He's similar to my irl boyfriend~
