Oh shit! Truthfully though, I see no reason why dogs > other animals. At least, if you're saying this is wrong, you shouldn't be eating other animals. If you eat other animals, why is this wrong to you?
All things which are possessed by Kabuto's Edos aside from Gedo Mazo
To think anyone is soloing all 25 odd Edos at the same time is just borderline insanity (So6P excluded).
There is no way to defeat Edo Madara, Edo Nagato and Edo Itachi when they're together. I already said after the So6P (sons excluded) Kabuto is the next strongest. Kabuto shits on everyone else. It's not a top 10 thing, Kabuto is just first, period.
Kabuto is the strongest shinobi after the So6P, what are people really debating? Edo Tensei is merely a summoning jutsu that is part of his power. People don't complaing if Jiraiya summons Ma and Pa, people don't complain if Nagato summons Gedo Mazo or Cerebus etc so I don't see why people are...
So, Hashirama > Edo Madara + Edo Nagato + Edo Itachi + Edo 3rd Raikage + Edo Muu + Edo 2nd Mizukage + Edo Sasori + Edo Deidara + Edo Kakuzu etc? That's new.
He most likely used a contract seal against Madara. All this does is remove any direct control the summoner has over a summoned creature. It does not remove or seal souls. That necklace which you're talking about helps with the suppression of Bijuu chakra. It does not remove or seal souls.
The view that Hashirama > Edo Madara is actually rather laughable, when not only can Shodaime not overcome Madara's power (Madara is a fusion of the two shinobi), he lacks any sealing feats :\
Been discussed before. Personally, I think the Eternal Mangekyou Sharingan's abilities overule the consequences of forbidden eye techniques, meaning that those techniques can be used without the loss of light. I don't see why Kishi would make such a big deal about the EMS when it would...
Some say he actually has a MS. This would explain how he is able to use S/T ninjutsu, how he was able to control Kurama etc. His 3 tomoe, I believe, cannot be this powerful.
