Ryōma as he appears in the manga
Ryōma (Japanese: リョウマ Ryōma) is a minor character in the Pokémon Gotta Catch 'Em All manga and a rival of Shū. He dresses as a samurai and owns a highly mischievous Farfetch'd.
Ryōma thought of Shū as an amateur Trainer when they first met. After the battle, Ryōma begins to respect him.
Ryōma first appeared in The Farfetch'd Swordsman's Challenge! where he stops Shū from catching his Farfetch'd, as Shū mistook it for a wild Pokémon. Ryōma explains that his Farfetch'd is unstoppable in terms of speed and power. This made Shū want to battle it in order to prove Ryōma wrong.
They go to Ryōma's dojo where the battle took place. Shū was in a disadvantage at first as Farfetch'd moved super quick. However, Pikachu was able to win using the technique, Thunder Sword, in which Shū came up. With Ryōma defeated, he returns the belt that his Farfetch'd took earlier.
| Farfetch'd is Ryōma's only known Pokémon. It was mistaken as a wild Pokémon when Shū first meets it.
Farfetch'd is a master swordsman who had the ability to cut anything and it was super quick, as Shū and Pikachu had trouble keeping up with its speed. During the battle, Pikachu was able to defeat it using a technique Shū came up known as the Thunder Sword.
None of Farfetch'd's moves are known.
