Snorlax is very gluttony when it is eating food. It is lazy when always sleeping.
Biography[]
Orange League[]
When Ash Ketchum and his friends arrived at the Grapefruit Islands, they discovered that a Snorlax was eating every grapefruit (pomelos in the Japanese version) in the orchards. It also knew how to swim, allowing it to travel from island in search of its food. Eventually, the group, with help from Jigglypuff, managed to stop Snorlax and Ash managed to catch it, though Snorlax's actions would ultimately work in the orchard's favor as he chose not to consume the seeds.
Snorlax remained on Ash's team right up until the Orange League final. After Ash won the Orange League, he left Snorlax at Prof. Oak's lab on a permanent basis, as he could no longer fuel its large appetite.
Gold and Silver series[]
In Ring Masters, Ash used Snorlax in the Sumo Conference (as its massive weight gave Snorlax an advantage) and it ended up winning. Later on, in Better Eight Than Never, Ash used Snorlax against Clair's Kingdra and it won the battle. During the Johto League, Ash used Snorlax in his battle against his long-term rival Gary Oak. Snorlax defeated Gary's Nidoqueen and Arcanine before being defeated by Gary's Scizor. Snorlax was also used in Ash's next battle against Harrison and defeated his Steelix and Hypno, but was knocked out by Harrison's Houndoom.
Ruby and Sapphire series[]
Upon Ash's return from Hoenn, along with May and Max, Snorlax made fast friends with May's Munchlax, possibly because of their evolutionary relation. In Wheel of Frontier, Ash used Snorlax in his battle against Arena Tycoon Greta. Snorlax managed to defeat her Hariyama with an Ice Punch attack and her Medicham with Body Slam.
Diamond and Pearl series[]
Snorlax reappeared in An Old Family Blend, where it had gone missing from its Poké Ball, like Ash's other Pokémon. Snorlax was found in the kitchen eating food. Ash tried to use it to battle Team Rocket, but it tipped over Team Rocket's Mecha while sleeping. Snorlax was shown defeating an unknown Trainer's Grumpig with Body Slam during the Sinnoh League.
Journeys[]
Snorlax appears when Ash and Goh visit Professor Oak's lab. During Ash's time there, his Pokémon gather around him as he revisits them, including his Snorlax.
