Martin's conch horn had summoned enemies all around them. Matt instinctively put up Reflect and Light Screen as soon as the battle started. Anthony went straight for Martin, and it didn't seem like he needed any help at the moment. Xeno, on the other hand, was attempting to attack a Swablu, but it was flying too high for him to reach it. Josh aimed a Water Gun at it, which caused it to lose a little bit of altitude, but it was still in the air.
"Go after the walking enemies, Xeno." He said. "I can handle the flying ones."
There were a lot of Pokemon soaring above them right now. There were two Swablu and a Starly at the moment, and that was just the ones that he could see. There were probably plenty that were hidden by the fog, as well.

 The Swablu that Xeno was trying to attack went for Josh, now that it saw him as a threat. It used Round, and did a good amount of damage to him before it was blasted out of the sky by another Water Gun.
"I'll never get all of them at this rate." Josh said, just as a Hoppip flew down from above. to replace the Swablu Josh just knocked out.
"Perhaps this will help." Matt said, pulling something out of Josh's bag. It was the Thunderbolt TM that he bought back when they were in Scale City. He completely forgot about it after Zane showed up in front of the hotel, and it's been collecting dust in his bag ever since.

 Without hesitation, Josh took the TM, pressing it against his forehead. The bright yellow disc emitted a soft glow for a moment, then faded to a dark grey colour. Josh threw the now-useless TM to the side. The Swablu that Josh knocked to the ground earlier flew back up into the air. It flew towards Josh, but it was interrupted by a bolt of electricity. That was more than enough to finish it off. Josh looked over at the other flying Pokemon.
"Come at me. I dare you."
