From Bulbapedia, the community-driven Pokémon encyclopedia.
Purrrr-sian (Japanese: VSペルシアン VS. Persian) is the 47th round of the Pokémon Adventures manga and the seventh round in the Yellow chapter.
The chapter begins with Blue in an unknown, barren location, just as his Pidgeot returns with a message in its talons. Thanking his Pokémon, Blue opens the letter from his grandfather, Professor Oak, and silently pores over its contents.
Faced with Yellow's demands for Pika, the Super Nerd Miles simply sneers a challenge for Yellow to take Pika back himself, and orders a combined attack from his Marowak, Persian and Paras. With Yellow kept at bay Miles escapes into the city, and as Erika struggles to get up Yellow decides to attack at full force as well. Much to Erika's dismay Yellow's 'full force' merely consists of Rattata and Doduo, to which Yellow explains that he released all the other Pokémon he had captured, seeking only true friends as opposed to filling up Pokédex entries. As Yellow leaves on Doduo, Erika orders one of her elite groups to follow, when she discovers the sketchbook Yellow has dropped. Flipping through the pages she finds detailed, annotated sketches on Yellow's three traveling companions.
In the middle of Celadon City, Miles gloats to himself as Yellow struggles to find him in the dark. Musing to himself of the pay he would receive from the old woman who ordered Pika's capture, and the prospects of experimenting on a Pokémon League champion's Pokémon, Miles swears revenge on the Celadon university he was kicked out of and plans his attack. As Yellow carefully searches, Marowak sends its Bonemerang to attack Yellow's team - Yellow's attempts to listen for the Bonemerang are foiled as Persian uses Scratch on the wall to create interfering noise. With Paras's Spore on Marowak's bone Yellow's team is slowly weakened, and a scream from Yellow elicits concern from Pika...
As Erika gets to her feet, she deduces that Miles must have found Red in order to use the latter's scent in engineering his bodysuit, and at this revelation her citizens suggests that Professor Oak be consulted. However, Erika proposes an alternative in Blaine: the fourth of the 'good' Gym Leaders who had once sworn allegiance with Team Rocket, and so the scientist is contacted at his Gym on Cinnabar Island.
