Olympia was ready to face Liam. She said that she wanted to do a double battle and sent out two Meowstic, one of each gender.

"[i]Meowstic, the Constraint Pokemon, and the evolved form of Espurr. When in danger, it raises its ears and releases enough psychic power to grind a 10-ton truck into dust. The eyeball patterns on the interior of its ears emit psychic energy. It keeps the patterns tightly covered because that power is too immense. Meowstic's appareance and move pool will vary based on its gender.[/i]"

"Let's see, two pure psychic types, so I'll choose these two!" Liam said tossing two Luxury Balls into the air. Plasma the Rotom and Sneasel emerged. Liam was caught up in the moment of catching Sneasal that he didn't realize until now that it held its evolutionary item. Liam peered out the window and noticed that during Olympia's battle with Shiranui it had grown dark.

"The Gym leader's Meowstics will face the challenger's Rotom and Snesal. Begin!" The Ref called.

"Sneasel, Hone Claws! Rotom, use Confuse Ray on the White one!" Liam called. Both moves worked successfully.
Olympia told her male Meowstic to use Disarming Voice on Sneasel, while she told her female one to use Shadow Ball on the Rotom. The female Meowstic hurt itself in confusion and Sneasel was hit.
 "Plasma, Confuse Ray on the other Meowstic! Sneasel, use Beat Up on the confused one. Sneasel used the multi hit move. Since Liam's other on hand Pokemon included: Jiraiya the Greninja, Sylveon, Sliggo, and Scarlet the Delphox, some of the attacks did a fair amount of damage.
 Olympia called for Disarming voice and Shadow Ball again. Disarming Voice goes off, but again the female hurt herself in confusion. Sneasel was knocked back by the attack. When he got up he spit to the corner of the ring. He stood back up and began yelling and he began to glow white. Sneasel's body began to change as he evolved.
 "Weavile!" He exclaimed when he finished.

"[i]Weavile, the Sharp Claw Pokemon, and the evolved form of Sneasel. It lives in snowy regions. It carves patterns in trees with its claws as a signal to others. They form groups of four or five that hunt prey with impressive coordination.[/i]"

Liam orders Rotom to use Discharge while Weavile uses Protect. Both of Olympia's Pokemon snap out of confusion. She orders the boy to use Misty Terrian while the girl uses Shadow Ball on Rotom. While being shocked, the Shadow Ball goes off, but the female Meowstic was still KO'd, due to hitting herself in confusion a couple times.
 "One of Olympia's Meowstic's is unable to battle!" The Ref announced as Olympia recalled it.
(Misty 1)
"Disarming voice on Weavile." Olympia called.
"Night Slash Weavile! Plasma, use Ominous Wind!" Liam called. Weavile got hit with the attack and was getting worn out. He wouldn't take another hit. The attacks went off, the Night Slash being propelled by the Ominous Wind. Weavile fell over from exhaustion after launching the attack. The combo KO'd the other Meowstic.

"Liam's Weavile, and Olympia's other Meowstic are unable to battle. Since Olympia has lost both of her Pokemon, and Liam has one remaining, he is the winner!" The Ref called.
 "You did it!" Liam cheered. He hugged Plasma and then hugged Weavile, who gave a weak smile. 
Olympia praised Liam on his battle, saying that he had raised some good Pokemon. She awarded him the Psychic Badge. Liam thanked her. She said that Snowbelle City has a gym. 
Liam turned to Shiranui, "Shall we go to the Pokemon Center and be on our way?"



*(When I woke up this morning, Olympia's appearance in the anime and how she does gym battles had been revealed. I went and used that .)
