Ok this is my second thread and I have questions about Tobirama I was hoping everyone can help me with. First of all everyone's argument against Tobirama being a top dog is the fact that he has no counters to the weapons of the mangekyou sharingan and this is valid. But with all the hate Tobirama had against the Uchiha (yes I know he respected and had some by his side) wouldn't he have at least studied some of these attacks and looked for ways to battle the Uchiha? Also if Tobirama was the one who fatally wounded Izuna isn't it possible he could have access to Izuna's DNA or be able to edo tensei Izuna and help him fight Madara? or at least use Izuna as a distraction while the kage fight Madara?
