Marina versus Kel

Kel frowned as his Camerupt was toppled so easily, standing his ground as the tremors made from the giant pokemon shook him.  "Make your own Earthquake" the Trainer said, and the pokemon obliged, standing back up on its feet  before rearing back and slamming into the ground, shaking the earth in the area and raising the ground beneath the Rapidash into jagged shards of earth.

This Earthquake made the horse collapse instead, the friction from the sand digging into the Pokémon's heels and causing a lot of damage. Marina winced, it was a strong attack. This was going to be a close match.
"Another Low Kick, go!" commanded the trainer. The Rapidash performed the move once more, knocking down the Camerupt again.

Don slid backwards as he was hit again, but managed to make it back up onto his feet.  Kel frowned, knowing his Camerupt probably couldn't take another hit.  "Earthquake, oncemore!" he commanded, and the pokemon did as commanded, sending another tremor throughout the whole beach.

Estella could not take another Earthquake. It brought the Pokémon down with a final neigh. Marina returned the horse, doing her usual kiss of the Pokéball, and sent the Gallade back out. It went into the stance of a night, and Marina grinned at its determination. Let's finish this.

"Psycho Cut, go!" commanded the girl. The Gallade nodded, running forward in a fast paced sprint. Its arm was not a leaf this time, but rather a glowing purple blade. The blade pulsed with psychic energy, energy that was transmitted from the mind of the Gallade. It believed the blade could do damage, and so it was able to.
Before Marina knew it, the Gallade had struck its target with its arm, sending a wave of purple energy into the Camerupt. Direct hit. Marina watched silently for the Camerupt's reaction. Surely it couldn't take another hit...

"Caaaammmm" Don let out a bellow as the Gallade brought its blade down on his head. sending the purple wave throughout his body and bringing him to his knees. His eyes went swirly a moment later. "Good job, Don, return" Kel said, returning his defeated pokemon to the pokeball. "Good fight, Marina. Maybe we can have a re-match sometime," the trainer said, looking up at the girl and her Gallade who'd just barely managed to pull the win. Kel was already thinking of how he could have chose his moves or pokemon differently for a different outcome, though he tried not to let it show on his face. Next time, he'd win.

Upon seeing that she had one, the trainer was overjoyed, running to her Pokémon with open arms. The two embraced happily at their first win, Gallade trying to not cut her and smiling happily. The Pokémon didn't show too much happiness, as being a knight required a shred of tranquility, but he was obviously thrilled.
"I'd like that." Marina told Kel as he talked to her. She returned her Pokémon. "I'm going to go take them to the Pokémon Center..."
And with that she was off, a small pep in her step. Her first win. Maybe she could survive in this school after all.
