Ash nods his head and looks at his last Pokeball.

Ash "You are the last one let's show Julian how powerful you really are" ??

He took the Pokeball and threw it

Ash "I choose you"

As the ball spun it opened and suddenly a huge pokemon with wings emerged out of the Pokeball and roared loudly causing the whole stadium to shake.

It is his Charizard, it seems fairly big standing 1.9 meters, its long wings and sharp claws seems very intimidating and the flame on its tail seems to burn very brightly, Ash's Charizard is one of Ash's strongest pokemon or the strongest pokemon, after training in Caricific Valley then begin trained even harder under Ash training which Julian imparted to him, his Charizard has become very powerful.

What caught Julian's attention is the metal armor around Charizard and a Mega Stone in it, Julian looked at Ash's hand and noticed that he has a mega bracelet as well.

Julian 'I didn't even notice he was wearing a mega bracelet and his final pokemon Charizard seems like it can Mega Evolve as well, now this is interesting'

Julian "Gardevoir return"

Julian called out Gardevoir and took out his last Pokeball.

Julian "Let's go"

He said and tossed his Pokeball, soon the Pokeball opened and Tyranitar came out and landed on the ground causing it to tremor a little, Tyranitar roared and loudly stating his dominance from the start, his roar caused the crowd in the audience to shiver a little as they felt goosebumps.

Tyranitar looked at Charizard, Charizard did the same as well.

A face of between two powerful pokemon caused the whole stadium to get tense.

Ash "Charizard, Wing Attack"

Charizard flapped his huge wings and flew up high in the sky then its wings started to glow brightly and he dived down towards Tyranitar with full speed.

Julian "Stand your ground, let's see how tough this Charizard is"

Charizard knew that the Tyranitar in front of it is a monster and is waiting for Charizard to get close but Charizard is no joke either as it increases its speed and try to hit Tyranitar with full force.

Julian "Grab it"

Tyranitar stands his ground and as soon as Charizard is close to him he extends his hands and grabs on to Charizard's wings and tries to stop it.

Tyranitar gets pushed back a little but that all, Tyranitar is too powerful in terms of pure raw strength, he can bring down mountains, what can a flying lizard do.

Ash "Flame Thrower"

Charizard blasts a Flamethrower right on Tyranitar's face as it cannot get out of its hold.

Julian "Dark Pulse"

Tyranitar doesn't seem to be effected at all, he opens his mouth and releases a powerful Dark Pulse, it rips through the Flamethrower and lands on Charizard's face.

Tyranitar let's go of Charizard's wings and it is sent flying and crashing on to the ground.

Charizard gets back to its feet in a matter of seconds and shakes of the pain and roars at Tyranitar.

Ash "Charizard, use Dragon Breath"

Julian "Tyranitar Iron Defense"

Tyranitar covers his body with Iron Defense, the Dragon Breath hits Tyranitar but it has no effect on him due to Iron Defense.

Ash 'I have to get close if I need to deal damage to Tyranitar'

Ash "Charizard Steel Wing"

Charizard once again takes the sky and dives down at Tyranitar and this time it is using Steel Wings to take down Tyranitar.

Julian "Use Brick Break"

As Charizard was about to get close to Tyranitar, Tyranitar got in position to deliver a crushing Brick Brake.

Ash "Now Dragon Tail"

As soon as Charizard got close to Tyranitar, Tyranitar brought down his hand onto Charizard's head to deliver a Brick Break but Charizard suddenly turned and landed a powerful Dragon Tail on Tyranitar's belly.

Tyranitar got pushed back a little but he still seems fine after taking that hit.

Julian 'So he is taking advantage of Tyranitar's lack of speed'

Ash "Charizard use Dragon Breath again"

As Charizard is still close to Tyranitar it once again attacks with a powerful Dragon Breath.

Julian "Stone Edge"

As soon as Tyranitar hears Julian next command, he slammed his hands on the ground and suddenly blue glowing rock edges came ripping out of the ground, the first one deflected the Dragon Breath, the second one completely stopped it and the third one hit Charizard and sent it flying back to Ash's side.

Ash "Charizard are you ok?"

Charizard nodded and got back to its feet.

Charizard looked at Ash and pointed at the Mega Stone on its armor.

Ash "Yes, let's do this"

Ash said and flashed the Keystone that is in the mega bracelet of his, the Keystone started to shine and causing the Mega Stone on Charizard to shine as well, suddenly green light rays started to come out of Charizard's Mega Stone and fused with Ash's Keystone.

Charizard started to change, its size grew bigger along with its wings and tail, spines could be seen on its shoulder and knees, spike on its back and wings.

Julian could tell that this is a Mega Evolution that is completely different from the Charizard X and Charizard Y.

Soon Mega Charizard could be seen, its body had a combination of black and green flames.

Julian is surprised by this Mega Evolution as it is a completely new one.

Julian 'System what is its typing right now?'

System 'Charizard's typing is Dragon/Flying'

Julian 'I see, Mega Charizard X is a Fire/Dragon, Mega Charizard Y is a Fire/Flying, now this, let's call it Mega Charizard Z and this is a Dragon/Flying'

Julian looked at Mega Charizard Z and nodded.

Julian 'The Mega Stone that Ash found must have altered its hidden Dragon typing and made it its main type while it mega evolved, where did he find it, I might ask him later'.
