Totem Pokémon

Totem Pokémon (Japanese: ぬしポケモン Leader Pokémon) are a type of variant Pokémon that are battled at the end of every trial, having been up by the respective Trial Captain to fulfill that role. With the exception of Totem, these Pokémon appear larger and weigh approximately two to four times as much as other Pokémon of the same species.

In the games
At the start of a battle, Totem Pokémon are enveloped in a special aura which boosts one or more of its stats by a fixed number of stages. According to Wicke, their size and aura are a result of being bathed in the energy spilled from Ultra Wormholes, the same kind that the Ultra Beasts use to wield their Ability, which is further revealed in to be 's light. Totem Pokémon are battled in SOS Battles, which allows them to summon an ally to help.

SOS Battles with Totem Pokémon differ from regular SOS Battles in that their supply of allies may be limited, which allies they call is not influenced by the weather, and they call allies at specific times rather than at random (so their calls are unaffected by the Adrenaline Orb and status conditions). Both the Totem Pokémon and their allies have more advanced than wild Pokémon, mirroring Trainer behavior. Totem Pokémon each also hold a specific item, usually one that will synergize effectively with their particular strategies or cover their weaknesses. Due to the island challenge rules, Totem Pokémon and their allies cannot be.

Totem-sized Pokémon can be only obtained in Pokémon Ultra Sun and Ultra Moon, where they can be received from Samson Oak at Heahea Beach after meeting him for the first time at depending on the number of Totem Stickers the player has obtained.

Totem-sized Pokémon are -locked, and their sizes cannot be passed down through Pokémon breeding. Even if their species normally have multiple, Totem-sized Pokémon can only have a particular Ability, as listed below. The Ability is the species's Hidden Ability if the species has two standard Abilities, and the species's sole standard Ability otherwise; thus Totem-sized Pokémon's Ability cannot be changed by Ability Capsule. Totem-sized Pokémon always have at least three perfect IVs.

Totem-sized Pokémon that originally appeared as Totem Pokémon in are the only ones that can be traded to the original Sun and Moon games, and consequentially, can also be transferred to Pokémon Bank. Totem-sized Pokemon based on Totem Pokémon that only appear in Ultra Sun and Ultra Moon cannot be transferred to Pokémon Bank or traded to the original Sun and Moon games.
