I hate v4s, but I would have to say that v4 had the best characters. My first v4 adult was a Meidotchi/Maidtchi and I really liked this character... I also like Memetchi and Ichigotchi. Too bad Bunbutchi isn't on this one, I got him on my v3 and he became my favourite v3 character I also liked Minotchi (the v4/Entama Minotchi obviously, not the Mori one) and Yangu/Young Kuchipatchi.
