Ryu was first seen having a battle with his master, Clair. Although he fought hard, Clair's Dragonair managed to easily defeat his Seadra and won the battle. Although she stated that Ryu needed more training before he could defeat her, Clair praised his use of Twister and Smokescreen to block her vision. When Clair notes that a worthy challenger hasn't come by in a while, Ryu brings up the fact that only her cousin Lance was able to best her in battle. This angers Clair, who proceeds to kick Ryu in the face.
Ryu was considered to be interested in Clair as seen when he mentioned about her family history.
|Seadra is Ryu's only known Pokémon. It was first used to battle against Clair and her Kingdra. Although it attempted to use a combination attack against its evolved form, Clair switched to her Dragonair and defeated it with Dragon Breath.|
