Current Kabuto.. only has 4 edo's I believe.
Madara cant be counted as his summon anymore. He released the technique.
He still has his DSM
Sage Art: Inorganic Reincarnation (not effective , if he isnt in cave no spikes)
Sage Art: White Rage Technique
Also, Sound 4
Kimimaro -Dance of the Seedling Fern
Tayuya- Sound Genjustu
Jirubo-Earth Release: Earth Shore Return
Kidomaru- Spider Web Unrolling
He has Taka abilities
Karin- sensory, and healing ability
Juugo- absorbing natural energy
Suigetsu- liquidity ability
He doesnt have any of Orochimaru abilities anymore , so he cant use body shedding technique or any snake justus.
I think Kabuto rank on top dropped. But, where? He at rank 6.
small question: Wouldn't Kabuto need more human sacrifice to use edo again? Remember he did release the technique.
