Prompt: Rival Jack would like to battle! What will trainer do?

"Not that I have not been in showdowns more bizarre than this," Omi says, "but what are we doing?" He looks at the strange device in his hands and begins attempting to pry it open with his fingers.

Clay shrugs. "Don't look at me, lil' buddy," he says, looking across the strange stadium they're suddenly in. "Your guess is just as good as mine."

A familiar cackle echoes from the other side of the stadium. "Rival Jack would like to battle! What will you Xiaolin losers do?"

Kimiko looked down at the little red-and-white sphere in her hands for a moment before recognition flashed on her face. "I think I know what the showdown is, guys." She grins and tosses the device into the field. The sphere opens, and a burst of light emitted from it, revealing a small fox-like figure. Kimiko's smile grows wider. "A Vulpix—awesome!"

Raimundo blinks. "Seriously? A Pokemon battle? I've always wanted to be in one." He throws his own device into the field and smirks. "I choose you... Braviary? Sweet!"

"Ooh, ooh, me next!" Omi, too, tosses his Pokeball into the field, followed by Clay.

From across the field, Jack Spicer made an incredulous sort of noise. "No fair—a Poliwrath and a Torterra? You guys got all the good Pokemon!" He throws his own Pokeball into the field. "Oh. A Magnezone? Cool."

"Are we going to sit around all day, Spicer, or are we going to battle?" Kimiko says. She narrows her eyes as the Vulpix beside her opens its mouth and lets a stream of fire into the air above the stadium.

Jack narrows his eyes. "Let's go," he called out. "Xiaolin Showdown!"
