Osiris stabbed his spear through the chest of a Diaboromon even as Nova beheaded it with the GeoGrey Sword.
The creature continued to fight on, arms flailing, until Osiris growled, leaping back and impaling it once again, stabbing it through the Digi-Core...
"Damn it," he growled. He saw the dozens more Diaboromon coming at thme and knew they had no choice.
"Nova! Gatmuz! Ascend to your Burst Modes! We can't win this fight without that power! And quite honestly, more Diaboromon can't be worse than this!"
"RIGHT!" the two roared over the din of battle, leaping into the air and starting to shine with blinding light, Nova bursting into flame, Gatmuz shining with golden aura...
"Blazing courage, shining light, soar higher than before, ascend beyond mortal sight! When all seems dark, my hope shines bright, thus transform, overcome the blackest night! Burst Evolution! SHINEGREYMON BURST MODE!" Nova chanted.
"Chilling honour, shrouding night, become stronger than before, a star so deathly bright! When hope fades away, call upon the light, thus transform, overwhelm the black king's might! Burst Evolution! MIRAGEGAOGAMON BURST MODE!" Gatmuz chanted.
Fire and golden aura faded away, revealing the majestic forms of Nova and Gatmuz.
Nova's armour had become crimson and white, her GeoGrey Sword now a sword of solar flames and a shield of the same fire burning as she gripped it in her left hand. Her wings had ignited too, casting her draconic form into shadow as she spread them out, raising her blade and roaring a cry of hope "TOWARDS OUR FUTURE!" Her tial lashed the air as she started to fall...
Gatmuz had changed too. His claw gauntlets were gone, he now wielded a composite weapon made of pure golden energy, one end a crescent shaped blade, the other a mace head sphere. He spun the staff in his hand, his new mane of white hair blowing in the wind, blades of golden aura glowing on his helm as he descended...
"TORRID WEISS!" Nova roared as she landed, unleashing bullets of white-hot flame from her wings. The surrounding Diaboromon shrieked in pain as the the blasts seared into the flesh, burning them. Nova lunged for one of them and slashed off one of its arms with her blazing GeoGrey Sword, making it scream with agony even as she swung again, ripping off its other arm.
Gatmuz landed, blocking a blow with his staff before lashing out with the crescent blade "LUNA HOOK SLASHER!"
The blade tore through a Diaboromon, ripping it in half before Gatmuz spun the staff in his grip and swung again, slashing through its torso. Finally, he twirled it, raising the mace end over his head...
"FULL MOON METEOR IMPACT!"
He brought it down with a resounding burst of energy, ripping the unlucky Diaboromon to data even as he turned and sliced through another's arm with the crescent blade.
Nova snarled, kicking aside a dissolving Diaboromon and turning to Lazarus, leaping for the Piedmon.
Lazarus chuckled and immediately brought up the swords in his grip to block Nova's swing. The two blades hovering in the air slashed at Nova, but she blocked with her shield, angling the circle of solar fire to block each blow.
"You're dead, SCUM!" she roared, pressing down on his guarding blades with her great strength.
Lazarus chuckled "Clown Trick."
Suddenly, Nova was struck across the face with the very force she was putting into her own strike, hurling her back. She gave a feral growl.
Lazarus chuckled "you won't win, ShienGreymon."
"I'll have the last laugh here," Nova growled, pressing her sword and shield together "CORONA BLAZE SWORD!"
The sword and shield flowed into one almighty sword that shone with barely restrained solar power, burning in her grip as she gripped it with both hands.
"Laugh at this!" she roared, charging and raising the sword for an almighty blow to shatter his guard.
Lazarus chuckled again as he released his two swords and willed all four to attack Nova.
She was suddenly caught off guard as a sword sank into her unprotected back. With a snarl, she slashed at the blade, but missed as it sldi smoothly aside.
This began a ridiculous dance as Nova tried to dodge the strikes while also swinging to cut Lazarus's swords out of the air.
The Piedmon just chuckled as he watched her swing her great blade at the swords wildly.
"Laugh at this, chuckles!" Osiris growled "BLAZING SPEAR!"
Lazarus willed one of his swords to attack Osiris as the Raihimon lunged with his now-ignited spear. The Piedmon slipped aside and the spear missed as the sword swung at Osiris...
"Defense Shield," Osiris growled, bringing up his shield and blocking the slash from Lazarus's blade.
"This ought to be fun," Lazarus chuckled "now die, little Avenger. Final Spell!"
Osiris screamed as an almighty sonic burst erupted fromt he Piedmon, crushing him with pure sound...
He collapsed and Lazarus picked up his sword out of the air, lifting up the Avenger's chin with it and pressing the very tip of the blade against Osiris's throat.
"Die," the Piedmon said.
"You die!" Nova roared, slashing at him with the Corona Blaze Sword and slamming him into the glass floor. Lazarus cursed and stood, his four swords appearing around him and slowly revolving in the air, ready to guard against her blows.
"I was hesitant to use my power before," Osiris growled, standing and being supported by Nova, who held out a hand, still gripping the Corona Blaze Sword "but now I must and I shall. Nova, help the others. He is mine."
"But... Osiris," Nova said.
"Go," he said quietly "Nova... I won't ask again." She looked at him, seeing the determination in his eyes. "I can take him."
"Good luck," she whispered, laying a hand on his shoulder for a second before flying away.
"One lone Raihimon against me?" Lazarus chuckled "this will be quick, Avenger, and I can assure you, it will be painful."
"Oh, it'll be painful alright," Osiris growled "FOR YOU!"
His body was shrouded in darkness as he called on it, the ultimate force he wielded... the power of AncientSphinxmon...
"Frozen darkness, blackest heart, thus become Death, soul torn apart! I call on you, spirits of hate, come to me, defy your fate! Ancient Evolution!"
His body became armored in frozen darkness, Obsidian Digi-Zoid, far stronger than that worn by Raihimon, even as his body shape shifted, falling onto all fours, hands and feet becoming paws. His face became a death mask, rubies for eyes. His spear twisted like a snake, becoming his tail. His wings grew, becoming the great wings of Death, shadow of his coming.
"ANCIENTSPHINXMON!"
He exploded from the darkness, the God of Death, Avatar of the Darkness, AncientSphinxmon...
The Ancient Warrior tackled Lazarus, Piedmon crashing to the ground as his swords glanced off of Osiris's Digi-Zoid hide like rain off of glass. The great sphinx stepped forwards, force of his footfalls cracking the glass underfoot.
"You are done, Hand of Dracul Samhain," Osiris growled.
"You dare speak his name?" Lazarus spoke.
"His name is fear," Osiris said "and I am not afraid. I do not fear the darkness, I AM DEATH! DARK ROAR!"
He reared up, roaring as he crashed down and launched his sphere of focused darkness with all the force of an Ancient Warrior, sphere exploding agaisnt Lazarus and almost casually hurling the Piedmon across the glass, growls of pain escaping the Black Hand's lips as he hit.
Osiris padded towards him, an unstoppable dreadnought of Obsidian Digi-Zoid, Death incarnate.
Lazarus was not impressed in the slightest.
He stood, two swords leaping into his grip, the remaining two hovering around him. He charged towards Osiris, leaping into the air, over the power of the Ancient Warrior's Necro Eclipse and onto his back. From there, he twisted, slashing his swords across Osiris's weak neckplate.
Osiris howled as the swords cut deep, blood gushing from the wounds inflicted by Lazarus's swords. The Piedmon cackled and renewed his attack, adding his telepathically controlled blades to the attack and cutting deeper.
Osiris screamed in pain, collapsing even as Lazarus leapt away. The AncientSphinxmon was forced to release his advanced form and his armour shattered like glass, his body shrinking to Raihimon, then Anubismon.
He lay there, motionless and pathetic, Lazarus standing over him with sword held high to end Osiris's life...
"NO!" Nova and Gatmuz roared as one, slamming into Lazarus and slashing him with their weapons, forcing him away from their stricken mentor even as Nova broke away to block the assaults of Diaboromon, desperate for the easy data.
"NO!" she roared "YOU DON'T GET HIS LIFE WHILE I BREATHE!"
"NOR WHILE I FIGHT ON!" Gatmuz roared, tossing Lazarus away with his Full Moon Meteor Impact and joining his comrade, their Burst Mode auras reflecting off the glass and causing intricate plays of light.
"Then you die," Lazarus said, standing and raising his swords "crush them."
The Diaboromon charged, and the two desperate Digimon began their last stand, standing over Osiris's stricken form, Corona Blaze Sword slashing through Diaboromon, Gatmuz hurling them away with energy bursts from his Full Moon Meteor Impact.
The combat was desperate, a fabled battle, fire and light side by side against darkness, two warriors against dozens of foes...
Their breaths became ragged gasps. They bled from dozens of cuts. Their arms were weighed down as they tired, injuries sapping their strength.
Even their incredible strength, born from their desperation and Burst Modes, started to fade, weakening them.
Nova was crushed against Gatmuz as a Diaboromon hurled her away with a sweep of its arms.
"We're dead," she whispered "Gatmuz... I..."
"We're not dead!" he snarled, slashing a Diaboromon with his staff, hurling it back.
"We can't win!" she replied.
"We can hold them off," he said "if we unleash everything we have. Are you with me?"
"Yes," she said, understanding. Gripping Osiris, they took flight, ascending over the Diaboromon.
"TOWARDS OUR FUTURE!" they called, their Burst Mode auras exploding with power as they released all their energy together...
"FINAL SHINING BURST!"
"FINAL MIRAGE BURST!"
Fire and Light exploded, unleashing a terrible star of energy that held for but one second before unleashing the power of a supernova, detonating and slamming the Diaboromon away, swatting them against the glass below, searing their bodies to nothing...
The deathly star was pure white, searing with roiling power that washed across the land, burning screaming Diaboromon to nothing, cracking the glass with intense heat, melting it...
Lazarus barely escaped, running from the blast and hurling himself into a crevice, cowering away from the white-hot power being unleashed by Nova and Gatmuz together...
Then, as one, the two turned towards the pyramid and focused their power, unleashing it as a blast that cleansed the black stain of Diaboromon, opening a momentary passagve to the pyramid.
"GO!" Nova roared through the flames as she and Gatmuz finally lost all their power, Burst Modes breaking as they fell like falling stars to land on the glass below, shrinking back into their regular forms...
