Ankha #1 and Bob is #2. It has nothing to do with tiers. I liked them the most ever since the Gamecube days, way before there were tiers or the ability to trade villagers.
Lobo. <333 He moved out about a year ago when I didn't have time to play, and I completed the 16 villager cycle to get him back and am just so happy. ;w;
Although I originally loved Gaston for awesome buddy reasons in GC, I ended up loving Bam so much haha; my favorite color and a really spiffy animal-type : ) Plus I really tend to put him together with Rosie as in my game I tended to see a lot of interaction between the two^^
