*BOOM*

An explosion illuminated the skies as two beings faced each other. One was a normal human, he was tall and possessed an extraordinary physique. With his blue eyes shining through his long blond hair, he stared at the creature in front of him.

He was the size of several buildings stacked on top of each other, with black scales covering his whole body. A dragon, with his long neck, stood tall, staring down at the human with his fierce and beastly red eyes.

"You have improved, Gideon. To be able to counter one of my attacks so easily, you could say that I'm slightly proud."

The dragon's voice made the earth tremble, making anyone tremble equally in fear.

"Do not patronize me, Rex Draco, today will be our last battle!"(Gideon)

"You sound pretty confident, should I put such confidence to the test?"(Rex Draco)

"Come."(Gideon)

With those words, the dragon's black claws rushed forward to obliterate Gideon, who cleverly charged his legs with a golden aura and jumped high, avoiding the attack.

Without wasting a single second, Gideon swung his great sword, sending a moon-shaped slash towards the black creature.

The slash gradually grew in size until it met with the dragon's counterattack. Instead of the usual ball of purple flames, the dragon shot a shockwave of pure unstoppable power, making the slash dissipate and the hero to be thrown away a few dozens of meters.

*Fwoosh0*

Far away, where the hero landed, a brilliant golden light, accompanied by a huge shockwave, appeared.

"Overdrive, huh?" (Rex Draco)

Overdrive was the hero's innate skill/technique, it allowed to boost the user's strength, speed, magic and aura almost hundredfold, at least at the level the hero was now at.

"I should take this a little seriously then." (Rex Draco)

The dragon's body was enveloped in purple light, and his body started to become smaller and smaller.

Finally, the light receded, revealing a more human-like body.

Rex Draco now had a humanoid body of around 210 centimeters in height. Large black wings, black scales covering his body like armor, a tail full of spikes, his face covered by a fearsome black mask made from scales, red light seeping through the slits in the mask meant for his eyes, and finally, jet black hair flowing down his back reaching his waist, it was unruly and wild reminding one of a lion's mane.

Gideon's figure appeared with a flash, staring into Rex Draco's eyes.

Without uttering a word, both of their fists collided in the middle, a shockwave spreading a golden and purple aura into the surroundings.

Still without saying anything, they both attacked again, Gideon with his great sword and Draco with his claws.

*BOOOOM*

Another explosion occurred, and they both had to take a few steps back.

Sliding into the ground, blowing dust up into the air, they both prepared for another exchange.

Rex Draco charged forward, his right claw covered with purple flames.

In response, Gideon raised his left hand, and a magic circle appeared in front of him.

"Sing a song of seasons!

Something bright in all!

Flowers in the summer,

Fires in the fall!" (Gideon) (A/N: This is part of a poem called Autumn Fires by Robert Louis Stevenson)

Flames, golden, rushed forward from the magic circle, hurrying towards Rex Draco.

"Useless!" (Rex Draco)

Swinging his claw, the flames covering it were expelled forward, colliding with the golden flames of Gideon's spell.

*Boooom*

An explosion rang out, forming a cloud of dust. Expecting Rex Draco to appear amidst the cloud of dust, Gideon changed his stance.

However,

"Gotcha!" (Rex Draco)

Rex Draco had tricked him. Using the cloud of dust as a cover, he used his high speed to sneak beside Gideon.

Before the hero could react, he was struck with flame-covered claws that pierced the side of his torso.

But Gideon was a petty man, raising his left hand, he commanded his aura to form a physical construct, a dagger. A golden dagger quickly settled in his grip, and he swung it down towards his enemy.

"Aura Construct?!" (Rex Draco)

The golden dagger pierced his armor-shaped scales and pierced his skin and flesh.

Finally, the pain settled for both of them.

"Ah!! F*ck!!!" (Rex Draco)

"Ugh!! Damn it!" (Gideon)

Using their regeneration, they both healed themselves and stared resentfully.

"It's the first time you actually drew blood from yourself." (Rex Draco)

"Yes, last time you only backed off because Astra used the tower of condemnation spell." (Gideon)

"That still hurts nowadays, and it's been five years since then." (Rex Draco)

"Shall we go all out, now?" (Gideon)

"Oh? So you figured me out, huh? Alright, let's go!" (Rex Draco)

And with those words, the surrounding area was completely obliterated as they transformed.
