Man, the first had a number of demons under his control, and like, what, distributed them like trinkets and baubles all over the five countries in the name of peace? When the hell did these demons become ninja play things? wtf?

This has the side effect of making the fourth look less legendary. I mean, the first took out madara, who apparently was using the nine tails during their fight, and had a number of demons under his control, and the fourth dies in battle against it? Whatever. A can of crap has been opened and it's going to take a lot of toilet paper to fix this.
