Giant Pokémon, while rarely playing a large part in terms of plot, are nonetheless a recurring theme in the Pokémon anime and games. There are several episodes that have a plot revolving around unusually large Pokémon, such to the point that it seems to be a rather common mutation for Pokémon to go through. All Totem Pokémon shown in the anime are giant Pokémon.
Pokémon at Pokémon Land in Island of the Giant Pokémon are not listed here, despite the episode name, because these were robots created for the amusement park and not organic in any biological way.

Temporary giant Pokémon
In the games
In the core series
In Pokémon Gold, Silver, Crystal, HeartGold, and SoulSilver, although no giant Pokémon make a direct appearance, a legend stated that a 100-foot-tall Bellsprout formed the basis for the central pillar of Sprout Tower.
In Pokémon Ruby, Sapphire, Omega Ruby, and Alpha Sapphire, there are two men living in Sootopolis City who want the player to bring them large specimens of Barboach and Shroomish. Likewise, in Pokémon Emerald, the same two men want the player to bring them large specimens of Lotad and Seedot.
In Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, Totem Pokémon are a type of variant Pokémon that appear at the end of Alola's island trials. Due to the influence of the energy emanated from Ultra Wormholes, these Pokémon appear larger and weigh approximately two to four times as much as other Pokémon of the same species. In Ultra Sun and Ultra Moon, the player can obtain Pokémon the size of Totems by collecting Totem Stickers and presenting them to Samson Oak at Heahea Beach.
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, Pokémon have size variations; Pokémon that are size L and XL are larger than average, though these size differences are not visible.
In Pokémon Sword and Shield, a phenomenon known as Dynamax can make a Pokémon temporarily grow to giant size, upgrading its moves into Max Moves in the process.
In Pokémon Legends: Arceus, there is a variation of Pokémon known as alpha Pokémon. These Pokémon are known to be larger, stronger, and more aggressive than normal Pokémon and have red eyes. The Noble Pokémon (particularly Avalugg) and Ride Pokémon that the player encounters as part of the game's story are also bigger than other Pokémon of their kin. Additionally, all Pokémon come in various sizes, with some being dramatically larger than others of their species.
In Pokémon Scarlet and Violet, there is a variation of Pokémon known as Titan Pokémon that are considerably larger and stronger than normal Pokémon. There are also five vehicles called Starmobiles that the player battles during the ★ Starfall Street ★ storyline which are each installed with Revavroom that are larger than others of their species. Additionally, Pokémon once again come in a range of sizes, with some being significantly larger than average.
In the spin-off games
In Hey You, Pikachu! one of the activities involves Pikachu fishing, and it is possible to fish Pokémon much larger than average. There is also an Oddish that, instead of evolving, grows larger when it is watered, until it is at least ten times Pikachu's size.
In Pokémon Ranger: Guardian Signs, Hocus attacks the player with a giant Crobat when he is faced in the Sky Fortress.
In the Super Smash Bros. series, the player can temporarily be enlarged by eating the Super Mushroom. Additionally, Jigglypuff's Final Smash, Puff Up, can make Jigglypuff temporarily gigantic, plus knocking out any opponent near it.
In Pokémon GO, Raid Bosses are giant Pokémon with stats that are higher than that of regular Pokémon. Once defeated, they will shrink down to normal size and can be captured. Also, as in recent core series games, Pokémon vary in size; Pokémon that are size L, XL, and XXL are larger than average for their species.
In the manga
The Electric Tale of Pikachu
In Haunting My Dreams, Sabrina was attacked by a giant Haunter called the Black Fog. The Black Fog was an unusually large Haunter which had lived in Lavender Town since ancient times and had a Dream Eater attack powerful enough to suck out one's soul. Ancient people had treated it like a god, and due to this, it eventually chose to kill itself with Self-Destruct rather than be caught by Ash.
Ash caught a giant Slowpoke in Ash vs. Gary, but gave it to Gary soon after in exchange for a photo of his sister, May Oak. After being traded, it evolved into a Slowbro.
Pokémon Adventures
In Pokémon Adventures, Dragonite are generally shown larger than they usually are, as with some other Pokémon.
Yellow arc
In Make Way for Magikarp, a giant wild Onix was used by Bruno as a battlefield in his battle against Bill and Lt. Surge on Cerise Island. This particular Onix is much longer than normal, allowing it to be used as a stone bridge.
Pokémon Gold & Silver: The Golden Boys
In A Huge Mysterious Tree!!, Gold encountered a giant Sudowoodo blocking Route 36. However, it soon turned out that Sudowoodo only seemed giant due to the multiple layers of mud it had gathered on itself, and once those were removed, all that was left was a normal-sized Sudowoodo.
In The Truth About The Mysterious Whirl Islands!!, Gold encountered a giant, one-hundred-year-old Blastoise at the Whirl Islands. He was forced to defeat it in order to obtain a Silver Wing and meet Lugia.
In other media
Detective Pikachu
In Detective Pikachu, Tim, Pikachu, and Lucy encountered several genetically modified Torterra that had grown to the size of small mountains, referred to as the "Torterra Garden".
