Endgame weapon vs pre-hardmode boss
(Cain POV)
"Oi Obito, do something already, can't you see your little beast hasn't eaten anything yet? It has too much fat to fight against me!" well that is technically true, the Juubi just has been summoned and it lacks a lot of charkas to return to its prime form.
Well, there are a lot of moving food for it coming here so you don't need to worry about it Juubi, 'Hidan, has the allied shinobi force arrived yet?' I send a message to Hidan
'They are coming very close right now, my work is to stall for time right?'
'No, you can leave now and let them through, the Juubi has been summoned and it needs some charka to heal up. Try to get a good place to watch the show since this is going very ugly.'
Then the telepathy was cut off, she is rude as always isn't she? Whatever, the shinobi force will come here soon so I guess I will have to greet them in the most welcome way possible right?
"Bijuudama!" Oh, I nearly forgot about Obito, that man is still controlling the Juubi and trying to kill me. At this point, I don't even bother to dodge an attack anymore and just take all of them on my own, I don't know if losing the ability to feel pain is good or bad, it's feel a little pointless now.
BOOM*
-23000 DUR
+50000 DUR
That one has double the power of a Rasengan shuriken from Naruto, still not enough to make me feel pain though.
"It's too boring if I just continue to take every attack from a weakened Juubi, let's me test out some of my new techniques. Annihilation push!" A force came out from my palms and spread in every direction, resulting in a large radius of destruction but still not being able to kill Juubi just as I expected.
Annihilation push is a simple combination between Almighty push and Dust release, it acts like Almighty push but destroys everything instead of pushing them away. Man, creating new skills from already existing skills is hard like getting a girlfriend but the result is worth the effort.
But it seems like we have some company here, the allied shinobi forces have arrived and witnessed my attack, pretty sure most of them has scared the shit out already. Standing here and letting them come wouldn't be a good idea since they won't be stupid enough to attack someone who has the power like me, right?
"Whatever, it's time for you to witness my true power Tobi, try your best to not fly off your mount"
Just as expected, Obito has become more serious fighting with me now so he start to use Juubi's attacks more serious now, but unfortunately for him, I got an unlimited amount of stamina so dodging those tails or hands isn't even a problem.
Welp, enough playing, it's time to do something crazy because I'm still in Bankai mode, such a waste of MP if I didn't do anything fun.
--------------------------------------------------------
(3rd POV)
The allied shinobi force arrived at the scene and saw something they would never forget: a man lifting a Bijuu with one hand. What's more terrifying is the man is looking at them and throwing the whole Bijuu at them!
"Im-impossible! RUN!" Gaara used all of his sand trying to block the flying Bijuu
But that effort was useless because Cain's strength can even throw a Bijuu at an average speed of a Jounin in his Bankai state, not including his Haki and a couple of enhancements.
*BOOM*
"AHHH, Something is draining my charka!"
"Let me get out of this place!"
"Help me!"
Cain - who has caused all of this mess - only scratch his head and smile weirdly at the shinobi's alliance, "I should have used Haki for more destruction, that kind of damage is too little compared to Juubi's size" Cain sighed
"Does all of the shinobi's charka enough for Juubi goes to the last phase though, I have killed a lot of shinobis since I have come to this world so I kind of worry about the amount right now."
"Lighting release: black panther!" Cain raised an eyebrow, not bothering to dodge such an attack
*ZAP*
"Bubble hand" is a simple skill created by using telekinesis and a bit of bubble and wind technique to make the hand more visible.
*BAM*
Darui was punched away by the nearly invisible hand and crashed to the ground, but he wasn't the only one. Cain abused his power and create multiple hands and throw the shinobi into Juubi or somewhere near its range.
*ROAR*
The Juubi suddenly release a huge roar and its skin started to fall. The once fatty beast is now standing tall on the battlefield, using its huge eyes to scan through the area and finally landing on Cain.
*Bijuudama charging sound*
'So even the Juubi has its hatred set on that man now, I didn't expect he could even make the Juubi hate him.' Obito thought and also notice his connection with Juubi is weakening due to the massive amount of hatred in Juubi.
Cain looked at the red Bijuudama ready to shoot right at his face and mutter "Oi oi, that can't be real right? There is no way I can take that boom while standing still. Heh, I think it's time to fight back a bit more serious, Bijuudama vs upgraded Bijuudama!"
"Absolute fire nova!" This skill is a combination of 3 powerful skills Cain have: Dust release, sin phoenix fire and Tail beast bomb. The power of this skill is basically: whenever it goes through, everything will burn even to the slightest particle.
(You can imagine that attack look like the Sun but a lot smaller)
"GO!"
*ROAR*
The two attacks were shot at the same time, each of them can easily strike fear into any shinobi's mind.
*BOOM*
The two bombs clash together, causing a blinding light all over the whole battlefield. The fire comes from Cain's skill make every shinobi in a 1km radius burn to nothing in an instant while anyone further than that has their clothes burned or simply die from the heat.
"This isn't a battle we can win" Shikamaru was lucky to survive the impact because his group has arrived late for the battle.
"Yeah, this is impossible, it's like the battle of god, mortal like us isn't qualified to participate," Ino said while trembling from the shock wave that was created by the impact.
*ROAR*
Back with Cain, he is standing proudly on Juubi's body which is burned to an unrecognizable state, even with its regeneration can't help Juubi to get up "HAHAHA... Look at you Juubi, so miserable. Oh and Obito, how are you doing? I'm sure getting burned by the sun isn't that fun but maybe you have your last beautiful moment before you die."
"Heh, did you think so? You are the one that should receive that sentence"
"Pardon me? What do you mean?" Then Cain saw it, Obito's hand seal and a trance of black Zetsu under Obito's body. Instead of getting panic, Cain give both of them the evilest smile he could form.
"So you have decided to reveal yourself Zetsu, preparing to betray your friend?"
The black Zetsu take over Obito's half-burned body and force him to perform a hand seal, "Cain, I don't know how did you know about my secret but that won't help you now because my mother will soon make her return to this world!"
Obito's Rinnegan flashed as he call out the Jutsu's name "Gedō - Rinne Tensei no Jutsu"
-----------------------------------------------------
(Cain's POV)
SO just as I expected, the black Zetsu has controlled Obito's body to use Rinnegan and revive Madara. Seriously talking, I don't even know where the hell did Madara come from but that wooden coffin just appears out of nowhere and Madara walks out of it, completely alive. Right now he is talking with Zetsu to ask about the current situation then plug out Obito's Rinnegan, couple with another Rinnegan black Zetsu give him he now has the perfect Rinnegan... great.
Well because I don't want myself to get ignored at this moment, I decide to cut in their conservation. "It's my honour to meet you, the ghost of Uchiha. May I ask if my appearance has messed up your plan?"
"Yes, I must say that I'm impressed, really impressed by your power that could defeat Juubi alone but that won't stop me with my plan to bring true peace to this world." Then he immediately performs a hand seal that makes the Juubi sucked into his body, I'm fucking screwed, aren't I?
"Be proud of yourself because you will be the first one to withness the power of God."
"If you are god then I'm the weapon that can kill god, you should prepare yourself old man."
