Guys I think Obito was actually fighting back against Madara's will.
When black zetsu started taking over his body he remembered Rin couple of times and thats why he went woooaahhhh!!
Coz the last time he shouted like that was when he saw rin's death.

When sasuke met naruto last time , naruto mastered only SM and sasuke asked for Itachi eyes to defeat naruto.
If Naruto manages to defeat sasuke in the war, sasuke will become more power hungry and tobi might give him the other rinnegan eye if sasuke agrees to sync with gedomazo.
Many of you guys probably forgot about outer path ability aka seventh pain of Nagato(himself wass 7th pain).
Nagato killed konoha ninjas who killed his parents without doing anything when he first awoke rinnegan and also he killed a chunin who tried to kill yahiko in the sameway.
I think seventh...
Kabuto alliance only made tobi's work easy as 5kages are busy dealing with edo-madara.
Tobi must be very very strong because he decided to take on all 5 villages by himself.
He should've had some kind of plan because he was very confident that he could defeat 5 kages , naruto ,bee and many...
During his fight with konan Tobi claimed that he gave rinnegan to nagato. I thought that tobi probably created some situations like konoha ninjas killing nagato's parents infront of his eyes so that he could awaken rinnegan powers.
Now it looks like tobi transplanted rinnegan eyes to nagato...
