At Pewter City, in the 4th chapter of the RBG saga of the Pokémon Special series, it was eating the market's food products and everyone tried to catch it, with little success. Red decided to help them, so he sent out his Bulbasaur and, through its natural resistance against Electric attack, subdued the Pikachu, giving Red the opportunity to capture it. The people were grateful for Red saving their businesses, inviting him over for a meal as a reward. Red then showed them the Pokédex info about Pikachu, along with its Pokémon Red and Blue Sprite, saying it's the reason why he was on a journey. Through the Pokédex, Red saw that this Pikachu came from the Viridian Forest.
