Bull. Shit.
Nagato > Hasirama > Madara > Itachi
Nagato would make Hashirama plant trees Nagato's garden all day. And if Hashirama Randomly decides to stop, all Nagato has to do, is give him the look on my signature. Good Game.
Nagato would make Madara watch all the Filler episodes in the Anime, and never let him watch any of the real Episodes. If Madara tries to look away, Nagato gives him the look on my signature. Good Game.
If Madara decides to take any of Hasirama's DNA, and learn Wood-Style, Nagato's got a new Gardener. Hasirama will thank Madara for taking his Job. But now, Hasirama's the one who watches the Fillers.
**Oh, and I'm reading about how you guys think Nagato < Itachi.
Nagato would put a leash on Itachi's neck and walk him around The Leaf Village. Itachi's already thinking about the scary look Nagato will give him if he disobeys. Good Game.
