He waved back at the buneary he crossed as he circled around the building one more time, allowing the wild pokemon to fall behind his peripheral vision. I hope the owners have some cute pokemon like that one, he admitted to himself of the buneary, wanting to at least pet it.

But he had somewhere to be, and time was wasting. So he kept shuffl onward.

Unbeknownst to him, a dark shadow loomed over the buneary, overtaking it as soon as he looked away. Or perhaps the buneary had been a trick of the mind, fading to black as soon as he looked away. It wasn't the first strange thing to happen. Either way Adrian continued on, oblivious to the haunting going on around him...

tl;dr skipping

Adrian was trying to utilize a New Mauville kiosk when a porygon2 appeared from the screen. Not on it, from it. He'd been pushed back onto his rump, using his hands to brace himself as he fell while the pokemon forced its way past.

And it seemed like it wanted to play ball.

He released his trevenant, ordering it to use branch poke, basically tickling the porygon2. As if it were a compulsory reaction however, the porygon2 spit out a psybeam that glanced trevenant's eye, and although it wasn't very effective it had a lasting effect. He became confused. In a daze trevenant lashed out with Shadow Claw, but the pokemon was unfazed by the ghostly claws raking it...

"Oh no you don't," Adrian rebuked with a well placed pokeball. In that time of distraction, he was able to withdraw his trevenant, and instead sent out his vulpix. By that time porygon2 had broken free, releasing a discharge of electricity.

It washed over vulpix without any significant results, but it had instigated her, stirring her into action. With naught but a glance the porygon2's discharge was disabled. From there it released another psybeam, only for the vulpix to nimbly duck out of the way, exhaling a puff of air so frigid, the moisture in the air was immediately crystallized and scattered to the winds. Porygon2 was frozen.

Adrian tossed a pokeball in his hand a few times before he threw it at the porygon2, figuring it best not to let it wreak havoc on the digital interfaces surrounding New Mauville. And then he set off.

Whether he'd ever find apartment thirteen was starting to become a serious question. As he took a flight of stairs down, a gengar faded out of a wall, frowning at the loss of its play thing...

tl;dr attempting capture
