I focus on transforming into my 4th form. And start channeling mana into my suit, at first, it's a stub, next, a tail, and then I start growing larger...and larger....and larger. Purple scales grow all over my body, my hands grow talons, my horn grow until they are 28 ft long and multiple ft thick. I grow till I am 140ft long and 70ft tall, ethereal smoke floating off my body.
'I think I topped his by a little bit.' I think while I smirk to myself. The entire stadium is quiet, and the red dragon is staring at me, his eyes trembling from fear. Then whispers are said throughout the stadium, "It's a dragon king."
"Impossible, no dragon king other than those from royal blood exist, none."
"I'm sorry, is his 140ft long form not evidence enough?"
"Let's see if he breaths black fire, that is only exclusive to Dragon Kings."
I then realize something, my mask! I look around on the ground, everywhere around me but can't find it. Then I have a thought, I check my face and it's there, covering my entire snout and even some of my head, but the mouth like carving is gone and is instead open? I move my jaw around, no restrictions, I then open it and realize, 'The mask....it changes with my dragon form! This is amazing!'
I then look at the trembling red dragon, "So are you still afraid of this ten year old?" The dragon nods his head like it's gonna fall off. Seemingly saying yes. "Ok, so I want you to stop shaking, and surrender." He nods ferociously and looks at the judge, "I surrender." Then he runs back into the room he came out of.
I look over at the judge, "Is that it? I was hoping for an actual fight." The judge swallows as the mask still translates my voice into a demonic carnation. I hear a slightly cocky and confident voice come from the crowd. "I'll fight you." I look over to see an 8 foot tall Dragonborn walk out of the crowd. He is covered in blue scales from head to toe and has wings on his back. He has a massive scar down his face from his left eye, over his snout and onto his right cheek. His voice sounds hoarse but emanates a power that can be seen by his appearance. He wears black armor that covers his entire body and a helmet that lets his horns show through.
'This guy emanates confidence.' I think to myself while I look down at him. And then I start hearing comments from the crowd.
"Is the Tidal Wave really gonna challenge him? He just showed up out of nowhere."
"I just got here what i...did Tidal Wave really just challenge this guy? He's big but has no battle record, I just checked."
"Mom, I'm hungry!"
'So this guy is named Tidal Wave, he is probably able to control water or something similar.' I think while I look at him. "I accept your challenge." There are gasps in the crowd as he jumps down from the side of the arena, his landing causing a few cracks in the ground. 'I feel this guy is powerful. Either that or a show off.' He walks over to the other side of the arena and all of a sudden, magical shields appear, protecting the crowds and holes appear from the walls.
"What the?" All of a sudden, I look at him, something odd grasping my attention. He has started transforming, his body grows, his wings combine and turn into large spikes with webbing in between on his back. His arms grow fins and his feet have webbing on them. When he is done, he is around 90ft long and 60ft tall.
'Son of a gun, he's a water dragon.' And as I think that, water starts flooding the arena through the holes I saw earlier. 'Dang it! I guess I gotta test out my form changing ability now.' I imagine my wings becoming smaller, fins on my arms and tail, my hands growing webbing, and my lungs becoming gills. Ping!

"Shadow Morph in Process."
"Mass change in form, creating new form.....done!"
—————————————————————
All of a sudden, I feel an immense wave of discomfort as my new form creates itself, shadows are dragged towards me. And when it's finished, 'I can't breath!' I start choking on the air and I panic, I stick my head into the water, relieved as I can breath again. 'Damn gills.' I stare at Tidal Wave as the water rises until there is about 50ft of clearance from the ceiling.
'So they do this to make sure it's a water battle, but leave enough space so the head can breath. Thank gosh for biology cla-' My thoughts are interrupted as I feel teeth try to tear into me. I look around and suddenly realize. I can't see. I look around my surroundings just to see a blue fog floating in the water.
'I heard of something like this, there is an underwater river in a lake somewhere on Earth that is made of a slightly denser liquid. Supposedly people get lost in it when you try to enter. So I should probably stay near the edge so I can't get ambushed as easily.'
I swim my way towards the edge and bump into the wall. 'Ok, now I gotta stay vigila-' I get head butted against the wall, water getting pushed out of my gills. And a blue blur flashes back into the fog. 'Okay, I lack experience in fights because of my young age and past life. I have only had one fight and that was with my speed advantage. I am unfamiliar in the water.'
'And my size is only a liability in this situation.' I look around to try and see him in the water, but only see fog. 'This is stupid, where the hell is he?' All of a sudden, I feel him bite into my leg, a little blood starts flowing from it, as I squeal from the sharp pain and pressure in my it, I take my leg and hit it off the side of the container. I hear a small yelp of pain and a small drops of blood float in the water before dissipating.
I see a set of blue jaws let go and blue scales blur away into the water, disappearing into the fog. I look down to see a few scales missing and some others cracked. 'My scales are as strong as diamonds! How the hell could he do that?!' All of a sudden, I see a blur and then a sharp bite into my arm and blood starts shedding quicker. "Screw this!" I roar as I grab him by his back fin in which he lets out another small yelp of surprise.
I heave all my strength and slam him against the magic barrier. I hear a shrill yell of terror and see blood cover us both, he swims away but is no longer a blur. I see his back is at a crooked angle. I go to swim after him but I feel a sharp pain in my arm, I look down at my arm to see teeth lodged in my scales, the ones that weren't destroyed.
I start pulling them out, roaring in pain as I tear each saw like tooth from my skin. A few scales are holding onto dear life as I finish tearing out the teeth. I look around, even more vigilant now that my victory is closer than it was before.
