The duo took their places on the battlefield. Selene's Rotom Dex flew out of her bag and flew over to the stands. The Former Champion took out a Pokeball and tossed it around in the air, waiting for when the other two are ready.

The Kahuna pulled down his hood and ran his hands through his hair, cause it was getting abit messy. He then took out an Ultra Ball from his belt and patiently waited for Marnie and Haven.

"Right then, I hope you know how to battle." Marnie said, before sending out her Leopard. She nodded at the dark type, who bounced up an down in understanding. "Alright, looks like we're ready to go. What about you, stranger?"

Haven, despite being unable to see heard exactly where the battle was coming from, and sent out a glittering Malamar, who swayed from side to side. Awaiting his first move.
"Alright children, let's get this battle underway!"

Selene took a moment to see what type of Pokemon they had. "Hmm.." She put away the Pokeball that she was holding and took out a Luxury Ball. "Do your best, Mimi!" She reeled her arm back far and threw it like a baseball, and out came a Mimikyu. The female just swayed her hips slightly with an adorable smile on her face.

Gladion closed his eyes, seeming to be pondering something. After a few moments, he opened them and threw the Ultra Ball, in sync with Selene. Out came a Lucario, who twirled his bone around for a few seconds, as if he was trying to show off. Gladion just crossed his arms and waited, with a stern and serious expression, the exact opposite from Selene's expression, allowing them to make the first move.
