Inside a small enclosed room with conveniently placed platforms decorating it, Sigma hefted his giant gun.
"I know, I know, I'm compensating for something," Sigma grumbled before Zero could open his mouth, "How would YOU feel if every reploid on the planet had a full head of hair and you didn't?"
"Does Signas have hair?" Zero asked X. X shrugged.
"He never takes off his helmet. It's creepy."
"Have you tried wigs?" Axl asked.
"Millions of them. Absolutely none of them look good on me. I always end up looking like the leader of a biker gang or a mad scientist. I deserve more dignity than that, but my head is just so damn oblong! Like a football someone inflated too much!"
Axl snickered. Sigma snarled.
"You were supposed to copy X and Zero's DNA! That way I could have implanted their DNA in countless war machines and make an unstoppable army not even they could defeat!"
"What war machines?" Zero frowned, "Do you have a factory of them lying around somewhere?"
"Ah! Er, yes. They're currently in development by my crack team of scientists."
X shook his head.
"Another half-baked plan that fell short. You really should have stopped after your best work in the fifth war – you really did destroy the world back then."
"Yes, but like insects, the human roaches still survived! I blew up the world and everything and they STILL exist!"
"That's why you should have stopped. You did your best, and your best was not enough. Why do you continue?" Zero asked.
"I knew he was getting more and more demented the more we destroyed him," X murmured to Zero.
"Hey! I heard that! Don't insult the man holding the really big gun!"
With that, he fired, and the three reploids scrambled for cover. The fight, as always, was very short, especially this one, because Sigma had something else up his sleeve.
"Now behold my true power!"
"Your destruction is assured, you have no chance to survive, make your time, etcetera," Zero yawned, flicking one hand to hurry things along. He stopped being snide when the room around them broke apart and they found themselves standing on top of rocks floating in the middle of what appeared to be outer space.
"Okay, this makes no sense whatsoever. We were on the planet, weren't we?" X wondered.
"Uh, doesn't look that way. That planet below looks an awful lot like Earth. And there's the moon!" Axl cried.
"Leave it to Sigma to drill plot holes everywhere," Zero muttered. A shadow blocked out the sun, and its owner was Sigma.
"Hi, guys."
"Good grief," Zero said, craning his neck. The Sigma before them was approximately the size of his giant head battle body back in the fifth war; a few storeys tall, except this time it was floating in outer space and had full mobility.
"This is not good. If we get knocked off these space rocks we'll fall to Earth and burn up in the atmosphere," X warned them.
"Finally, a bottomless pit that makes sense!" Zero exclaimed.
"What are we gonna do?" Axl squeaked. This was clearly his first epic battle and he found it hard to build up the same kind of confidence the two Hunters before him possessed.
"Relax, kid. He has to come within range of our weapons if he wants to use his," Zero assured him. Sigma launched giant green energy balls high into space above them, and they soon came falling from overhead.
"That is, unless he does that," Zero said, and everyone dashed out of the way of the fuzzy green balls of doom that plopped onto the space rocks. While they were distracted, Sigma zoomed in fist-first and tried to punch Zero off his narrow platform. Zero was far too experienced to fall for the simple misdirection and leaped over the fist, driving his beam saber into the palm, nailing the giant metal hand to the space rock. Sigma roared in pain and tried to retract his hand, but the rock possessed its own gravity and would not budge. So, he began crushing the rock in his hand.
"Alright, guys, you run along his arm and shoot him in the face," Zero ordered.
"Is he serious?" Axl sputtered in consternation. X rolled his eyes, grabbed Axl by the scruff and yanked him over to the nailed, struggling hand, pushing Axl before him up Sigma's arm. Sigma tried to shoot them off his arm with laser vision but only succeeded in burning chunks off his own arm as the spry reploids scampered along it like rodents.
"Insects!" Sigma bellowed as X and Axl hopped around his shoulders, burning his giant head with a rain of plasma.
"Insects that bite,"Zero pointed out, retrieving his Z Saber from Sigma's hand. While Sigma retracted his arm, Zero ran along it too.
"You know, I thought this upgrade was useless, but here goes! SABER EXTEND!"he roared, the Z Saber doubling in length. X and Axl dashed out of the way as Zero performed the coup de grâce, unseating the titanic oblong head from its shoulders.
"NOOOooooooo!" Sigma moaned, his cry fading into the void, the twisted grimace on the decapitated head fixed forever. Zero landed beside his comrades, sheathing his saber.
"That's great and all, but how do we get home?" Axl wondered as the headless body began to drift Earthward.
"Alia? ALIA!" Zero yelled into his comm.
"What? Wait, are you guys in OUTER SPACE? How did you get up THERE?"
"Ask Sigma."
"Where is he?!"
"In case you haven't been paying attention for the last ten seconds, he's DEAD! Now get us out of here before we join him!"
"Okay, okay, sheesh, let me fix the coordinates…"
888
When they reappeared, they were in the same futuristic temple as before, on the top floor, looking out over Neo Tokyo.
"Sorry for being Captain Obvious, but this isn't HQ," X said, as the place became that ominous rumbling which could only mean it was about to fall apart.
"Come on, this way!" Axl waved for X and Zero to follow. They were making good progress until Sigma, inexplicably alive, loomed up behind Axl, who freaked out and began firing shots that just bounced off Sigma's armour. Sigma punched Axl right through a metal wall
"Do you have any idea how much that STINGS?" Sigma hissed at them. Although he was in the same body that carried the giant gun, it was almost skeletal; most of it destroyed from the former battle.
"We can do that again, you know," Zero glowered at him, reaching for his Z Saber until several energy blasts hit the floor at his feet.
"X! Zero! My fight with you isn't finished!" Red called down to them from above, wielding his double scythe. As he landed between them, he kicked Zero out of the way, twirled his scythe and slammed it into X, knocking him across the room.
"How is he able to move after such a beating?" X grunted. Red moved in front of Sigma.
"Heh heh heh. Excellent, Red! Now let me use your body…"
Writhing metallic tentacles disgorged from Sigma's ruined body to enshroud Red's strangely unharmed body.
"Ugh, we go through hell, and now we have to deal with tentacle rape," Zero groaned, picking himself off the floor. Red laughed.
"Did you really think it would be that easy… Sigma?" Red said in Axl's voice, as the scythe transformed into Axl's blaster. Axl/Red shoved the blaster under Sigma's chin and shot the Maverick through a window. Sigma fell a long, long way down to Neo Tokyo's streets.
"Do you think he survived that?" X wondered, leaning over the edge of the broken window.
"Nah. It's a bottomless pit. Nobody walks away from those; not even Sigma," Zero said as Alia finally locked onto their coordinates and took them home.
And so it was that the seventh war ended.
