A round of creativity and flashiness, rather than combat, eh? Demor crossed his arms and lowered his hood as he looked around the stadium. So many contenders, so much Magic Power in one place. The Judges had their booth, the audience was countless and surrounded them entirely. The Male Drachini nodded softly to himself, and tapped his foot. Most of his spells and skills were purely combative in nature - this wouldn't be easy.
But then he saw it: Another Mage who could use Storm Magic, or at least Weather Magic of some sort, creating a Storm Cloud above the Arena, drawing many eyes towards it as the lightning arced between the clouds and Thunder roared. Many children and those scared of the thunder cried out in fear, and Demor's eyes widened, pupils narrowing into Reptilian Slits as he darted for the Mage, Lightning arcing around his body as he let out a loud battle-cry, drawing perhaps some of the crowd to look at him as he then shoulder-charged that mage, slamming them off their feet before crouching, and leaping high into the air.
"I Sure hope everyone can see this..." he thought to himself as he continued flying upwards, covered in lightning as used his Arc Flight spell to dart across the air within the Arena, the Yellow and Purple Lightning flashing and arcing beautifully as he flew from spot to spot, right into the clouds.
Then he began to inhale. Within seconds the Storm calmed, and after perhaps a minute, it became apparent that the size of the storm cloud was shrinking. Demor was EATING the Storm Cloud. More specifically, feeding off the Magic that created it, and using it to both sate his appetite and fuel himself.
It would take another couple agonizingly frighting minutes before the entire cloud was gone, and the sun shone through to hit the audience again. Lightning arced from the clouds to the ground, scorching the earth and kicking up small bursts of flame or dust. Once the cloud was gone, though, Demor remained floating in the air for a moment, before letting out a small, almost inaudible belch, and beginning to fall to the ground face first, smiling the whole time.
His body began to glow brightly, and then it began to shift. Feet and Hands became claws, his tail flicked out fast enough to make a whip's crack, horns grew from his forehead, flowing back against his skull smoothly before pointing upwards, and finally, great wings of Black erupted from his back.
Dragon Force.
Once entering this form, the light vanished and he spread his wings, stopping his descent immediately with a burst of air that spread across the field, kicking up more dust, making clothes in the audience flutter, and hats fly away. He then flew up without the need of his Arc Flight spell, flying over the audience and directly in front of the judges to make sure they saw him and considered him for the next round. As he did, he did a variety of tricks - flips and corkscrews and other fancy flying before launching bolts of lightning and water into the sky, the two bolts of magic meeting in a dazzling explosion of light and mist.
He'd continue to do this, and many other flashy things that came to mind as long as his transformation lasted, which based on the sun-blocking size of that storm cloud he consumed, would be for most of the first stage at least.
