From Bulbapedia, the community-driven Pokémon encyclopedia.
The old man (Japanese: おじいさん old man) is a small, grumpy old man that lives in Viridian City, Kanto. At first, he is very grumpy and will not let the player pass through to Route 2, until he has had his coffee for the day. This is just a barrier in the game, so the player will not wander past Viridian City until the player goes to the Viridian Poké Mart and delivers Oak's Parcel to Professor Oak.
After that, he starts to lighten up and help the player by teaching them how to catch a Pokémon using a Poké Ball. This is a guide for novice players in Pokémon Red, Blue, Yellow, FireRed, and LeafGreen. In Red, Blue, FireRed and LeafGreen, he catches a Weedle. In Yellow, he fails to catch a Rattata, then goes to the Poké Mart to get more Poké Balls; if the player talks to him again, he will successfully catch Rattata. In Pokémon FireRed and LeafGreen he will also give the player a Teachy TV, which teaches the player a variety of things about battling and catching Pokémon. His grandson, Primo, is the host of the show.
He appears again in Pokémon Gold, Silver, and Crystal, and Pokémon HeartGold and SoulSilver saying that he had his cup of coffee, which is revealed to be a double shot of espresso, and also tells the player he was once an expert at catching Pokémon. This is a reference to the events that happened three years before Generation II. Because Kanto is not accessed until later in those games, the old man will not demonstrate how to catch Pokémon; this role is taken by Route 29's Dude in Gold, Silver, and Crystal, and Ethan or Lyra in HeartGold and SoulSilver.
In the original Japanese games, the old man is not grumpy from lack of coffee, but rather passed out drunk. This was changed in English for obvious reasons, as this could be deemed as "unsuitable".
