General Radahn

Radahn's swords flew back to his hands with a purple glow, smacking against his palms with a thunderous shockwave.

Large boulders suddenly formed from the mounds of dead bodies, a grotesque mix of metal, bone, and flesh all crumpled together under the ancient thrumming gravity magic.

The four large boulders rose behind Radahn's form and floated for a moment before racing towards Aerion's prepared stance.

Aerion's spear was held loosely in his hands, distorting the air around it as his divine flame and dragon magic sparked and roared through the weapon.

The four boulders hurtled towards him, trailing blood in their wake. With one large swipe of his spear, Aerion released a concentrated wave of red lightning-infused divine flame.

The concentrated wave of red lightning-infused divine flame collided with the oncoming boulders, exploding in a brilliant flash of energy. The boulders shattered into fragments, their grotesque contents scattering across the desert. 

Radahn charged through the remnants of the explosion, his swords trailing arcs of purple magic. His eyes blazed with fury as he closed the distance between them.

Aerion's spear glowed with an intense heat, the flames dancing along its length as he braced for the impending clash. With a swift, fluid motion, he spun the spear in a defensive arc, deflecting Radahn's first strike.

Radahn pressed on with relentless aggression, his attacks a whirlwind of raw power. His swords moved with deadly precision, each swing a testament to his formidable strength. Aerion met each blow with calculated finesse, his spear a blur of fiery defiance.

As the battle raged on, Radahn's movements became more erratic, driven by the primal instincts the scarlet rot had reverted the once mighty Demi-God to. 

He unleashed a powerful downward strike, aiming to crush Aerion under the weight of his sword. Aerion sidestepped with lightning speed, his spear arching upwards in a counterattack.

The tip of the spear grazed Radahn's thigh, searing through flesh and armour. Radahn snarled in fury, his grip tightening on his swords. In a sudden move, he unleashed a wave of gravity magic, the force rippling through the air and distorting the battlefield.

Aerion was caught in the wave, his body lifted off the ground and hurled backwards. He twisted mid-air, landing in a crouch several metres away. The sand beneath him shifted, and he steadied himself, his eyes never leaving Radahn.

The Demi-God advanced with a menacing growl, his form towering and imposing. Aerion's mind raced, searching for an opening, a weakness to exploit. He could feel the heat of his divine flame coursing through his veins, mixing with the dragon lightning that crackled around him.

Summoning his inner strength, Aerion launched himself into the air, the flames propelling him higher and faster. He arced above Radahn, his spear poised for a decisive strike. Radahn's eyes widened in surprise as Aerion descended upon him, a blazing comet of divine power.

With a thunderous bang, Aerion brought his spear down upon Radahn, the tip glowing with an intense, fiery light. The Demi-God was able to bring up his swords to block the astronomical attack at the last second. 

The impact created a shockwave that resonated through the desert, the sands shifting beneath their feet. Radahn staggered, his swords falling to his sides as he struggled to maintain his balance.

Sensing an opportunity, Aerion moved to strike. Radahn however suddenly leaped into the air, defying gravity as the towering Demo-God vanished into the sky. 

Aerion blinked as he scanned the sky in confusion, his battle rush almost dissipating, only to be revived in full by the sudden glow on the horizon. 

His eyes widened and heart pumped as he recognised the blazing comet descending from space. It was the Demi-God hurtling back towards the battlefield with roaring fury. 

As Radahn descended closer, a trail of fiery meteors in his wake, each crackling with purple-tinged gravity magic, Aerion's exhilaration peaked. His burning orange eyes fixated on the approaching cataclysm, a battle maniac revelling in the ultimate test of power.

Aerion channelled every fibre of his being. His divine flame blazed fiercely, engulfing his spear in swirling fire. The air around him shimmered with intense heat as he gathered his energy, the flames casting flickering shadows across the sands.

Aerion filled his spear with his divine flame and dragon magic, the weapon now resembling a bolt of pure flame that sparked with red lightning. Vibrating madly, barely able to contain the immense power within.

With an exhilarated grin on his face, Aerion pulled the spear back and launched the bolt of divine power towards the descending Demi-God. The spear shot forward like a comet of blazing energy, hurtling through the air with incredible speed and ferocity.

Radahn's form smashed through the sound barrier with an ear-shattering bang, the shockwave echoing across the desert. The energy spear followed shortly after, sending aftershocks rippling through the sand below.

The Demi-God's descent only gained speed as he held his massive swords ahead of him, his gravity magic pulsating with blinding intensity. Aerion, feeling the exhilaration of battle coursing through him, braced himself for the final clash.

The spear screeched as it tore through the air madly, leaving a trail of scorching flame and crackling red lightning in its wake. Radahn roared like a lion as the Demi-God brought down his thrumming swords upon the flying spear hurtling towards him.

With an explosion of divine energy, Aerion's spear collided with Radahn's massive swords. The clash sent shockwaves rippling through the atmosphere, shaking the very foundations of the desert landscape. Lightning crackled and flames roared as the collision unleashed a blinding explosion of light and power.

Aerions lithe form down below watched in wide eyed wonder as he was suddenly thrown off of his feet by the shockwave, he vaguely saw a large form fall from the sky but didn't focus on that as he regained his balance.

The desert had completely shifted, the attacks shockwave flattened the massive dunes of sand that littered the red desert.

Another spear conjured into his exhausted form as he walked towards the sight of the impact, his eyes widened at what he saw. 

Radahns bloody barely breathing form, his golden armour torn apart from the impact turned into shrapnel as the metal exploded inwards. 

The Demi-Gods ridiculously sized body slightly shook from the aftershocks of power running through them, Aerion stepped closer warily.

The man's long dark maroon hair, previously a vivid red that inspired fear and hope on the battlefield laid messily against the ground below, the man's helm now torn into shrapnel.

The beast's breathing was staggered and slow, he noticed the severe blood coating the Demi-Gods frame and grimaced. 

He walked close enough that the General noticed his approach, his burning orange eyes almost flickering as it rested on his form. His arms thrashing usually at his sides, his body too exhausted to continue. 

At that moment Aerion remembered the old man's words. "Do it quickly, he has suffered enough" the words rang through his head as his eyes settled on the form. 

The beast's visage flickered. In that fleeting moment, Aerion envisioned him on the battlefield, gilded armour gleaming, a crimson cape that stirred both fear among foes and courage in comrades.

Walking alongside the General, Aerion peered into his wrathful eyes. Drawing nearer, he couldn't ignore the unmistakable signs of decay and rot.

This man, once the legendary Red Lion who embodied hope, was already long dead. His body now a mere vessel for the putrid decay of a fallen demi-god.

With swift and decisive action, a molten-tipped spear cleaved through the Red Lion's skull, ending his existence in an instant.
