From Bulbapedia, the community-driven Pokémon encyclopedia.
The 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 a 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, and Yellow, and Pokémon FireRed and LeafGreen. In Red, Blue, FireRed and LeafGreen, he catches a Weedle; in Yellow he fails to catch a Rattata. He will also give the player a Teachy TV in Pokémon FireRed and LeafGreen, 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 games where Kanto is not accessible, the role is taken over by a different character. In Pokémon Diamond, Pearl, and Platinum, the role is taken over by Lucas or Dawn while in Pokémon Ruby, Sapphire, and Emerald there is no one to teach the player how to catch Pokémon. Instead, the player watches Wally capture his first Pokémon.
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" by parent activist groups.
