"Geodude, Rock Throw! Sandshrew, Scratch!"
Gray watched as the two Pokémon launched their moves. Geodude punched the concrete, gathering a large rock in his stony hands, and launching it at Nidoran, while Sandshrew rolled towards Gible, claws glowing an eerie white. Gray knew that it wouldn't take him long - at all - to completely slice into these trainers, and he could tell that Nidoran was really, really close to evolving...so the boy opted to quickly knock the Pokémon out.
"...Dragon Rage. Double Kick." He commanded quietly, his voice only reaching his two Pokémon. Nidoran released a shrill cry, leaping into the air and flipping, so that his two back legs slammed against the large boulder. It completely tore through the rock, and Nidoran landed right in front of the Geodude. Another Double-Kick slammed against the rock-type's face, and stone chipped off, as the Geodude was launched backwards and into it's trainer.
Gible, meanwhile, took only a second. It roared, releasing a large blast of Dragon Rage at the rolling Sandshrew, catching it mid-roll and, similarly, sending it flying towards it's trainer, knocked out. The two Lackeys dragged their Leader away, while Gray leaned against the wall, watching another trainer walk up. This one was a female, and she grinned, throwing out a Poke-Ball with an overdramatic flourish.
"Let's Dazzle him, Roselia-!" She began, but was cut off as, Roselia, whom was in the middle of twirling for Gible, was suddenly blasted back into the stone wall due to a Dragon Rage slamming into it's small body. Oddly enough, it wasn't knocked out - just stuck in the wall...but one more Dragon Rage knocked it out fully. The trainer gazed fearfully at Gray, before sniffling and returning her Roselia, running out of the school.
Gray's face stayed carefully stoic as he collected his winnings, after returning his Pokémon. For now, a break. With a grunt, he sat in his winner's circle, taking out a bottle of water.
