Kiba and Shikamaru totally
Hinata for online with Sakura and Ino or Kiba as supporters.
Gaara for against my bro with Konan and Sasori as support
Or any Yaoi/Yuri pair up that I like: Temari+Hinata, Naruto+Sasuke, Naruto+Kiba, Sakura+Ino(Which is pretty good if Ino is a support), Shikamaru+Kiba
I really only play singles in local matches but I main Konan.
For teams I guess I like using my favorite characters (Hinata, Lars) to back me up rather than a competitive team at the moment. But because I haven't really explored all that teams has to offer in terms of gameplay. (From a competitive standpoint)
