"And now...let's get things rolling with our next match! From a research lab far away, this creature was created to be the world's most strongest Pokemon...and they succeeded! Now it lurks within Cerulean Cave, bringing with it chaos and destruction as it battles unsuspecting trainers. Now...A Legend Reawakens!" Cra Ne said. "So...we introduce...Mewtwo!" he said as the Pokemon floated down to the arena with a serious expression.

"Whoa… No matter how many times I see him, his aura is still very sharp." David said.

"Well it was created in a lab and has mistrust against humans. Can't really blame him for keeping everyone on edge." Starlight said.

"Indeed, such a creature deserves peace away from those who caused him pain." Y'shtola said.

"I already took Incineroar. Leia, you and Reshiram may have to take this one." Zacian said.

"Yeah...no problem." Leia said as she headed down there.

"And...for his opponent! She has faced the wrath of the dragons of the Unova Region and even tamed the white dragon. She is the Tamer of the Yin! So...let us introduce...Leia...Rolando!" Cra Ne said as Leia walked in.

"Hope you're ready. Bring it on!" Leia said.

"And the location is...the Unovan Pokemon League!" Cra Ne said as the two arrived outside of a large castle. "Let the battle...begin!"

Mewtwo started by gathering energy in his palm before firing off a Shadow Ball.

Leia starts to spin her staff to block the attack. "Cerberus Strike!" she said as she dealt a three-hit combo with her staff.

Mewtwo then started to levitate her before tossing her towards a wall before she went and recovered by poking her staff into the wall.

"Whew… Close one." Leia said as she got back to the arena. "Tsunami Strike!" she said as she sweeps her staff before twirling it and deals a strike from the opposite side.

Mewtwo then teleported behind Leia before striking her with a Confusion attack.

"Oof… Head's starting to get a bit fuzzy." Leia said as she tries to pull herself together. She was then sent back with Disable as Mewtwo glowed before it floated there as Mega Mewtwo Y.

"Oh...that's not good." Dan said.

"Mewtwo must be going for a quick finish." Twilight said.

Mega Mewtwo Y then started to gather psychic energy before unleashing it towards Leia in a large burst.

"Uh oh… Reshiram, need some help!" Leia called out as she used Burst with Reshiram. "Not enough...I need to counter with a blast of my own." she said as blue flames gathered in her hand.

"Psystrike!" Mewtwo called out telepathically.

"Blue Flare!" Leia said as both attacks collided with one another.

"Whoa, those two are very evenly matched in this state." Zacian said.

"Both are legendary in their own right. But the big question now is who will overpower the other." Titanica said.

"Ready to bust out a new move we've been working on, Reshiram?" Leia asked as her spear lit on fire. "O crimson explosion, lend us your power!" she said as flames start to surround Mewtwo. "The fury of our flames shall burn all to cinders!" she continued as she prepared to attack. "Burst Mystic Arte! Inferno Drive!" she called out as she charged right at Mewtwo with a powerful thrust.

Mewtwo attempted to guard only for the thrust to break through his defenses, piercing right through him as his Mega Evolution faded as he descended right to the ground and fell unconscious.

"Alright, she did it!" Teepo said.

"And thus...the winner of this fight is...Leia!" Cra Ne said as the audience cheered.

Leia reverts at the announcement. "Whoo! That's the stuff!" she said as she helped Mewtwo up, or at least...she brought him to her back. "Hoo… You know how to work your opponents to the bone, do you?"

Mewtwo nodded in agreement before it teleported away as she was left smiling. "Take care of yourself." she said as he had vanished.

"Nice work, Leia. You were on fire out there. Literally." Alvin said.

"Thanks. Just wanted to show off my best." Leia said.

"Not to mention that Reshiram is a great partner for you as well. You two really came together." Zacian said.

"We certainly do." Leia said. "Just like how Zekrom works well with Spectra and...N."

"Ah, still thinking about him, huh?" Genis asked.

"It's hard not to sometimes. I just hope wherever he is right now...Pokemon are being treated fairly." Leia said.

"I'm very certain they are." Zacian said.

"Yeah...hopefully one day...we'll meet again, my friend." Leia said.
