Rodan locked his eyes onto his target. This was his territory, and it was being defaced. Rodan beat his wings hard, rising high into the stratosphere, his fiery glow pulsating as bright as ever filling the evening sky like a glowing ember.
The creature then tucked in it's wings and dived down towards the smog monster. It spread its wings slightly curving its dive so that it would hit its foe at the right angle.
The Smog Monster reared backwards, waving its forelimbs about in the air. The underside had grown isopod like armour plates and with the many sharp limbs it was clearly a fighting stance. But Rodan was simply stronger.
The fired demon hit the Smog Monster with full force, releasing a sonic boom as it flew past. Its sharp talons shredded the armour of the creatures underbelly like eggshell, digging its claws deep into the flesh.
Rodan roared at the creature in its grasp as it continued to fly with it helplessly squirming to try and escape. Finally Rodan let go of the creature, letting it fly through the air and into the heart of the city of Buenos Aires, where it flew through two buildings, demolishing each and landing in a heap of rubble against the third.
The creature groaned weakly in and attempt at a roar. Rubble had pierced it's already battered skin in a thousand places. The monster watched definitely as Rodan slowly approached, oozing blue blood from many lesions.
Once Rodan arrived he bit the creature on the head, piercing deep into where its brain would presumably have been. He then flipped it over leaving the smog monster helplessly on its back in a pile of debris, unable to right itself.
Rodan stepped over the smog monster and roared down at its feeble squirming body.
HRUUAAAAAAAAAAAAAAAAAAAAAARRRRRRRK
Despite being all but powerless The Smog Monster worked its way into a somewhat of an upright position and burbled a weak sound of defiance.
Without hesitation Rodan once again trusted its talons into the creatures mangled underside and began to flap his wings. The two titans rose through the air, much to the awe of onlookers.
Rodan beat his wings forcefully, bowling plumes of dust into the air with each beat. The two titans rose through the air, rising above the setting sun in a somewhat ethereal spectacle.
The smog monster began to use its forearms to scrape away at Rodan's leg to which Rodan responded by reaching down and tearing one of the limbs off with his beak and flinging it away.
As Rodan ascended the monster slowly began to grow a tail. It grew longer and longer, its tip of it bubbling and sputtering as it elongated. The mutation seemed to take something out of the creature, its eyes growing dim.
Finally when the tail was around 30 metres long, the tip straightened out into a point and began to harden into a black sinewy spike.
