Pseudo-immortal team :

Main - Mu
Kabuto - GNW Hinata

Pretty fun to troll people with, but nothing that could be used super competitively (Every main has some advantages they can provide this lineup with)

You may also want to team up Choza, Kabuto, Danzo

Giving you not only full chase, but also incredible amount of heal (Kabuto and danzo gain health and chakra whenever something dies. Choza gains life whenever you get chakra), of course water main with even more heal still won't hurt.
