And what happened ? Itachi broke out, foddered Nagato and released Edo Tensei.
Also let's not forget about the Edo Kages. (Left to right)
2nd Mizukage (Trollkage)
Mū (Second Tsuchikage)
3rd Raikage (A's/4th Raikage's Dad)
4th Kazekage (Gaara's Dad)
• Gold Dust
• Ultimate Shield and Weapon
• Genjustu specialist/Troll
• Dust Release
• Camouflage Technique
• Splitting in 2 Technique
I bet he could have done a lot with this, he could have done wayy more damage using them fully possessed, from the start.
Would have maybe even taken out Onoki, and Gaara.
Ginkaku and Kinkaku, the survivors from the Kurama's stomach after being swallowed alive.
Kabuto could have used these guy's to the maximum if done correctly. He could have taken a lot of other people if it wasn't for his care free attitude.
Kimimaro. Although he is not praised as much as we he got first introduced he still is badass, but got fodderized by some sickness. He could have gone all out in a war like these, and he probably did since he didn't get that much canon screen time.
Kakuzu. He's also badass.
• 5 Creatures (With each his own Element Attribute)
• Stores people's heart in his body
What more could you ask for? And because he's an Edo Tensei there's no need to worry about his heart, or regeneration. He's OP as it is.
I feel like he could have done a whole lot more then he did.
He could have token out millions with his poison gas if Kabuto wasn't so careless. (That also led to his downfall) (No Wanking)
To be fair, his Edo's were up against an army. Stands to reason some of them would get sealed. But even then, I feel you. Deidara alone should have guaranteed victory, but he failed to use him effectively. In fact, you couldn't ask for a better Edo than Deidara. Madara made it clear that the Edo Tensei's purpose was to wipe out everyone, including the caster of who used the Jutsu to murk the field. That is the only mistake I could not forgive. Losing to Itachi was O.K to me. Even though Kabuto was arrogant, he literally was THE ULTIMATE Uchiha counter. I could can understand him getting cocky. Too bad that led to his downfall.
His over cockiness could be one reason. But, it's more or less the plot. If he had used the possessed Kages and controlled them from the start... Naruto's shadow clones would have been destroyed, the sealins wouldn't of happened....
And if he entered the battle field himself; He could of demolished a lot of shit! It's more or less... The fact that Edo tensei needed to be nerfed so . . What happened happened.
But if you want some other answer; Arrogance, trouble micromanaging all Edo's, and never being in a war.,
