Obito

"Naruto, how far away?"  Tsunade asks

 "Two minutes on arrival.  I can already hear the fighting, Kakashi-sensei's team is already there "Naruto says anxiously in his voice.

 "How are they doing against Madara?"  He asks the Raikage at the control station, which monitors all ninja squads

 "Sasuke, he's fighting the masked man, and for the moment, neither of them seems to outdo the other.  On the other hand ... Kakashi and his team are fighting against Madara, but ... He is destroying them all, using only Taijutsu.  He also owns the Rinnegan " comes the grim response from the control tower

 "Rinnegan ???"

 "This is the Madara I have known, he is just playing with them.  His power is immense, but at that time he did not possess the Rinnegan, " says the Tsuchikage with little hidden fear.

 "We just have to fight it us Kage, the Mizukage is coming back.  It is the only choice we have left, "says the Kazwkage solemnly

 "Tsuchikage, why don't you tell us about Madara's abilities, you should be the only one still alive, to know something," Raikage says, hoping to find some useful clues for the upcoming battle.

 "Are you calling me old?  Uff .. However, I do not know his abilities, the only time I saw him, just a glance was enough to make me lose the will to fight him "he says sadly 

 "Then there is no way to discover his abilities," says the Kazekage

 "Some skills, I can tell you", I say addressing them

 "Raijin, tell us everything you know," Raikage says, looking me in the eye

 "I can only assume some of his abilities, as he possesses the Rinnegan, it means he can use the same abilities as Pain, also like Uchiha he is surely able to use the Susano, like the black flames Amaterasu."  I tell them about the techniques I remember Madara can use at the moment

 But before anyone can speak, let's hear Tsunade, "WHAT ???"  who screams in surprise, after answering the headset connected to the tower

 "What happened Tsunade?"  Raikage asks with concern

 He freezes for a couple of seconds before speaking "nothing too important, just a discovery that shocked me.  Apparently Sasuke managed to remove the mask from the fake Madara. "

 "Who is the masked man then?"  Raikage asks, a little annoyed, by Tsunade, who doesn't complete his sentence

 "… Uchiha Obito, we thought he died during the third world war.  But apparently, he is not dead, and he remained in the shadows to carry out this plan, of the moon's eye "

 ...

 After about two minutes, we manage to get to the battlefield, on the one hand, I can see Sasuke fighting Obito.  And I can see, that at the moment, he is not at a disadvantage against him, but, it is better to send him reinforcements.

 On the other hand, the situation is totally different, I see that Madara hasn't killed any Ninja yet.  Not because he can't, but because he's just playing with them.  And as if a Kage battled Genin, this is Madara's true power.

 "Kakashi, you and your team go help Sasuke, we'll take care of Madara" Tsunade says, once within earshot.

 "Yes Hokage-sama," Kakashi says, leading the team towards Obito

 "Oh, I see more ants have arrived. You should be the Kage, and the nine-tailed fox and a ... Cat," Madara says, seeing us replace Kakashi's team.

 "So you would be Hashirama's niece, you are weak, very weak compared to him" she says looking towards Tsunade

 "Oh, I see that little Onoki is there too, you have become senile, to want to fight me" he says looking at the Tsuchikage

 "You are threatening the world, with your plan, even at the cost of my life, an old man like me. He has to stop you" he says with burning eyes.

 "And then there's the cat ..." Madara starts talking again, but I cut him off

 "that (cat), he could kick your ass" I say to him

 "hahaha ... Yes, Obito told me that you would be interesting, I can't wait to find out. I'll let you make the first attack, get under" he says with a battle maniac smile

 Tsunade turns to us and says "to beat him, we should fight together, the Raikage and Naruto, will be ahead, while me, the Kazekage and the Tsukikage, we will support from afar. Raijin, you find an opening to attack. It will be difficult, but  the fate of the whole world depends on this battle "

 "Received!!"

 "You are finally ready .... Let's dance!"  He says after seeing the movement on our part
