Wally has a kind, calm, gentle, shy and passive personality. Unlike most of the other Pokémon game rivals such as Blue, Silver, and Barry, who often taunt the player and love to show off, Wally doesn't. Instead he is more shy and cautious with the things he does, and is extremely humble. He is frail and sickly, but despite this, he tries to be brave. When he catches his first Pokémon, Ralts, he begins to gain an inner strength and confidence that builds within him throughout the game. Later, he becomes quite the powerful and skilled trainer, who challenges the player just before they exit Victory Road.
