(A few more to go.)
The battle that was intense before, only got bigger with the heroes and the late arrivals battling the robots with all their might. Kakashi charged a Raikiri and eliminated five robots, Guy and Lee were using their Taijutsu to trip up and knock more robots into each other, Hinata and Neji combining their Hyuga family talent damaged the robots body's, Shikamaru used his Shadow possessing jutsu to halt some robots in place while Chouji bowled them over, Kiba using his own family technique with Akamaru each taking out two robots. Sakura was using her raw strength to pound one robot sending it crashing into five more blowing to pieces, "Cha!"
Asuma took in a breath and blew ash around six robots confusing their senses before launching a fire jutsu at them frying their circuits, "Well this is getting to be exciting."
"It's not over yet Asuma." Kurenai said while avoiding an attack from one robot and grabbed it by the arm swinging it into another.
Karui and Omoi were following Bee's lead using their sword skills to slice the robots into pieces, "Oh yeah this is great!" Karui cheered.
"But what if our luck runs out?" Omoi asked worriedly.
"Yo Omoi don't be hasty, Killer Bee's serving up something tasty!" Bee called using his sword maneuver to slice eight robots in a single blow.
"Bee focus, remember the fate of our lands are on the line!" A called as his right fist was powered with chakra, "Raigyaku Suihei (Lightning Brutal Horizontal)!" he wrist chopped nine robots heads off.
Shino was using his bugs to affect the circuitry inside the robots making their movements freeze up, Kankuro was using his ninja puppets to attack three robots, Gaara was using his sand abilities to crush the robots like he did to any enemy he faced in the past.
Ao and Choujuro were surrounded by ten, "Kid you're up!" Ao called.
"Hai!" Choujuro pulled out his dual swords encasing them in chakra forming a mallet and swatted the robots breaking them to pieces.
"Not bad for a young whippersnapper, but let the older generation show ya how it's done!" Oonoki called utilizing his Dust element, "Jinton: Genkai Hakuri no Jutsu (Base World Separation Technique)!" He encased some robots inside a giant cube and their bodies were broken down into nothing.
Finally Jiraiya was using fire jutsu against Kabuto who fought back using Orochimaru's own snake jutsu, "You've really lost it, Kabuto. Having to embed Orochimaru's own genes into yourself?"
"Well I guess that makes me the new Hebi Sannin doesn't it?" Kabuto smirked.
"Hardly!" Jiraiya punched him in the face sending him backwards.
Cyclops had blasted a few more until the robots were totaled, "There we got through their defense."
"On the contrary, this is only round one." Mordo said as the robots whose pieces were littered on the floor started automatically repairing themselves and another armada of the same robots stood.
"You gotta be kidding me." Wolverine groaned.
"Smythe just had to install repair programs within these robots." Spiderman sighed.
"Attack!" Dormammu ordered as they fought again.
Meanwhile Catastrophe had gotten past the robots and was going toe to toe with Madara, "You are very persistent for a Jinchuriki."
"Because we're more than your ordinary Jinchuriki, and we will make sure you never forget it!" Catastrophe called planting his palms on Madara's torso as a seal appeared on it, "Kai!" he called.
Madara groaned as swirling out through the hole in his mask was Itachi, "What but how?" the Uchiha founder growled.
"We Uzumaki ninja are experts in the field of sealing jutsu." He reminded the older ninja.
"Arigato Naruto, now let's attack together." Itachi said as they were about to attack Madara only for Dormammu to even the tag team.
"I will not have everything I've been planning for fall apart like this!" he launched fire blasts at them only for Itachi who summon a spectral being to block the attack.
"Susanoo?" Madara gasped.
"That's right, and with my better vision I can hold onto this more than I could before my hazy vision." Itachi replied as Catastrophe and him launched a water projectile at Dormammu dousing his flames a bit but hardly affected him physically.
"Your jutsu is still no match for me!"
While the guys were still fighting the robots, they were all getting restless, "If we don't think of something soon, I don't think we're gonna make it!" Spiderman panted.
Suddenly Smythe came back pushing the portal device he built to beam Dormammu into their world, "Sorry it took so long, thought you could all use a hand." He pulled out a control and pressed a red button. Suddenly all the robots self destructed one after another.
"Smythe, what is the meaning of this?" Mordo demanded.
"Emergency self destruct program, for desperate measures of course." Smythe answered.
"You traitor!" Dormammu growled.
"Sorry Dormammu, but I made other arrangements!" he started up the portal probe and aimed it at Dormammu opening another portal and put it in reverse pulling him in.
"What, no!" Dormammu called as he was pulled into it and because of that millions of life energies were pulled out of the portal and were sent flying off in multiple directions.
Just about each one had returned to the bodies of those who had their life force absorbed by Kabuto. Some life forces whose bodies were indisposed of moved onto the after life while some bodies that were being looked after got theirs back and woke up. And one particular life force returned to Konoha and went into the motionless body of Sasuke Uchiha. Sasuke groaned as he opened his eyes looking dazed.
Back at the Akatsuki HQ, the portal was getting stronger and the guys were taking cover to avoid being pulled in, "Alistair, shut it down!" Catastrophe called.
Smythe tried but it didn't respond, "I'm trying but it's not responding."
Spiderman and Iron Man looked at Kabuto remembering last time they faced Dormammu and Carnage, "Guys we have to send Kabuto in there as well!" Spiderman ordered.
"You got it!" Neko called launching her Nibi fire blasts at Kabuto sending him through the portal.
Kabuto unleashed his shadow snakes at Catastrophe, "You're coming with me!" he caught the Symbiotic Jinchuriki pulling him in.
"Naruto!" the girls cried.
"Smythe not yet!" Spiderman ordered before he decided to close the portal.
"But the portal!"
"We're not leaving Naruto in there!" Spiderman argued.
Catastrophe and Kabuto fell into the other dimensional void of Dormammu's, where the entity himself stood on a floating rock, "Well it seems I shall have a chance to finish you here!" he launched his fire blasts for the symbiotic ninja who jumped away after escaping Kabuto's grip and saw the portal still opened.
"We got to get out of here!" he tried to get back to the portal but was being delayed by his two enemies, "Kage Bunshin no Jutsu!" he summoned an armada of clones to hold them off while he made his way back to the portal.
Back at the HQ, Mordo was still launching magic blasts at Dr. Strange who wasn't giving up without a fight, "Mordo for your crimes against all that is good in magic, you shall join your master!" he fired a giant magic blast form his wand launching Mordo into the portal.
Madara watched seeing he was outnumbered, "And now Madara you're next!"
Demolisher called as the symbiotic ninja fired their most powerful attacks at Madara who was unable to perform his time warping jutsu thanks to the seal Naruto placed on him and was sent hurdling into the portal with Mordo.
"If we don't shut it down now, we're all going to be trapped!" Smythe warned everyone.
"Naruto will make it!" Demolisher called, "We know he will."
Back in the other dimension, Mordo and Madara landed and the wizard spotted his master facing off against an armada of Catastrophe's, "Master!"
"Mordo! Stop him!" Dormammu ordered his minion as the real catastrophe was heading for the portal.
Mordo attempted to use his magic to restrain the symbiotic ninja but Catastrophe activated Kyubi chakra extending a red chakra claw swatting Mordo away with Madara as he made it to the portal, "Arrivederci, we're out of here!" He jumped back to the portal and reappeared back at HQ.
"He's back shut it down now!" Spiderman ordered as Smythe shut down the machine sealing the portal.
"We did it!" Tenten cheered as all the symbiotic kunoichi powered their symbiote forms down.
Meanwhile back in the other dimension, Dormammu growled, "No the portal's been closed!"
"So we're stuck here?!" Madara asked in outrage.
Kabuto frowned at the three, "I knew I shouldn't have trusted any of you!"
Dormammu frowned at Kabuto and Madara, "And I knew I shouldn't have trusted you two! Well since we're going to be here for a long-long time, we might as well have a little fun!" he launched fire blasts at the two and soon it was a battle of Dormammu and Mordo vs Madara vs Kabuto that would be sure to last for eternity.
Back at the HQ, Iron Man and War Machine destroyed the portal device so it would never be used to release Dormammu again, "So that's it isn't it?" Kiba asked.
"It would appear so, Kiba." Shino nodded.
"That's right." Naruto said as his symbiote form powered down.
Suddenly the whole room started warping, "Hey what's going on?" Ino gasped.
Suddenly floating into the clear was Madame Web, "Congratulations everyone, you have saved not only your world but all other dimensions as well."
"Hey it's what we've been training for." Naruto reminded her until he suddenly remembered, "Madame Web, what about Sasuke shouldn't he be?"
The elder woman held out a hand, "Relax all is well. Sasuke has awoken and he is just fine."
"That's good, but what about you, Itachi?" Sakura asked.
"Yeah what're you going to do now?" Spiderman asked.
"I have to continue living out my life as the bad guy. Mine and Sasuke's paths will cross again, and when they do he will have fulfilled his ambition and killed me." Itachi explained.
"Itachi." Naruto gasped.
Itachi smiled, "It's all right, what matters is that my brother is safe from Dormammu and the ninja lands are safe. I thank you Naruto, and all of you for helping me take down my former master. But it's time I went on."
"We won't forget your bravery Itachi." Naruto saluted him and he saluted back.
Madame Web used her powers to teleport Itachi back to their home dimension, who left for parts unknown. Spiderman then turned to the old woman, "Well Madame Web, now that Dormammu's defeated we can all go home right?"
"Not quite yet Spiderman."
"Huh, what else is there for us to do?" Thing asked.
"Not you my friends, but rather Naruto." Madame Web motioned to him while everyone looked at him as well.
"Us?" he asked.
"Yes for you have one final task to perform, and I want everyone here to bare witness to it all." Madame Web teleported everyone to Konoha's Chunin Exam stadium inside a meeting room.
"The Chunin Exams stadium?" Kakashi looked around.
"So we're supposed to be fighting something?" Naruto asked.
"Not something Naruto, but rather someone." The elder woman explained.
"But who?" Naruto asked until he got his answer.
"Us."
Hearing that everyone turned around and gasped with wide eyes and slack jaws. Naruto spoke, "No it can't be!"
"Am I seeing what I think I'm seeing?" Black Cat asked.
"If you are then we're all nuts." Captain America answered.
Standing before them were eight figures, one of which was decked out in black and gray armor with red spikes and prongs covering it and another was wearing a green outfit with golden armbands and shield on his chest, and had a green face helmet that looked like a dragon head, but the remaining five all looked like Naruto each one wearing a different outfit, and one had red hair while not wearing a village headband anywhere on his person.
"Naruto meet… Naruto." Madame Web introduced them.
(And the finale is almost here.)
