Ryou is a member of the Elite Trio of Team Rocket, a group subservient to the Team Rocket Triad.
On Cinnabar Island, Ryou and Team Rocket Grunts search the Pokémon Mansion for Blaine. Later on, with Moltres in his possession, Ryou manages to obtain the upper hand against both Blaine and Red. Red makes a comeback, however, after sneaking away to Blaine's secret laboratory and resurrecting an Aerodactyl, defeating Ryou and Moltres. Ryou later reports back to Sabrina to hand back Moltres.
On Hand Edit
|Gengar||Ryou's Gengar is used while battling Blaine. When Team Rocket discovers Red spying on the battle, Ryou threatens to kill Red with Gengar if Blaine does't cooperate.
Gengar knows Night Shade.
|Moltres||Ryou was temporarily loaned Moltres to take care of Blaine. Though Moltres overwhelmed the two, Red was able to revive an Aerodactyl and do enough damage to cause Team Rocket to retreat. Ryou returned Moltres back to Sabrina later on.|
