He's a healer that deals 1-3 damage to all your ninja each turn (to proc passives like the curse mark) and creates clones to soak up hits. He's good for teams that setup his chase and he can help with chases that require 10 hit combos since each of his clones perform a slap attack.

I used Kabuto/Kakashi/GNW Kiba forever and it combo'ed around 7...? - with 10+ hits, depending on if I remembered to switch my summons after Kyuubi XD Anyway, summons are they key with Kabuto combos, it's too hard to build a good team around a ninja that has one chase T_T

For my fire team I use: Scarlet Blaze, 2* Choji, Kabuto, and Anko and they all combo great together. Anko & Kabuto really compliment each other's chase abilities.

Hinata/Kakashi/Kabuto, work with almost every main, 8 hit combo from anything.
