Titan Pokémon (Japanese: ヌシポケモンLeader Pokémon) are a type of variant Pokémon encountered in the "Path of Legends" storyline of Pokémon Scarlet and Violet. They appear much larger than other Pokémon of their kind, and they guard the Herba Mystica, rare ingredients said to be able to restore health instantly when eaten.
200 years ago, the Area Zero exploration team, led by Heath, discovered the Herba Mystica hidden deep within Area Zero, in the Great Crater of Paldea, located in the center of the region. They recorded information on the herbs in the Scarlet BookS/Violet BookV and gave the Herba Mystica their proper name. They subsequently discovered that the Herba Mystica comes in five different flavor varieties with separate healing effects. Due to this discovery, the team attempted to grow the herbs outside of Area Zero, in different sites around Paldea, but before they were able to harvest them, the herbs were eaten by Pokémon, leading to the first appearances of Titan Pokémon. As a result, the project was abandoned.
During the events of Pokémon Scarlet and Violet, specifically the Path of Legends story, Arven and the player would face off against the six respective Titan Pokémon. After defeating each Titan, Arven collects the herbs and makes sandwiches in order to heal his wounded partner, Mabosstiff.
Pokémon Scarlet and Violet
Titan Pokémon are ordinary Pokémon empowered and grown to gigantic proportions by the Herba Mystica they eat. There are a total of five Titan Pokémon fights to accomplish. Each Titan Pokémon is fought twice; the first fight is done alone, while the second fight is done together with Arven. After defeating a Titan Pokémon as part of the story, it can be encountered again in the same area it was fought as a normal-sized Pokémon (albeit one that is the largest possible size for their species), where it can be caught. These Pokémon will have the Titan Mark, which allows them to be given the title "the Former Titan"; they are also guaranteed to have an IV of 30 for all stats.
The Teal Mask
In The Teal Mask DLC, a similar battle state known as Titanic is achieved by the Loyal Three after being resurrected, implied to be caused by the villagers of Mossui Town feeding them Kitakami Mochi made with special herbs.

Every Titan Pokémon is battled in multiple phases. First, the player will encounter one as larger-than-usual static encounters in the overworld and battle it. Once its HP is below 10%, it will retreat to its Herba Mystica location to recover and power up. Arven will then join the player to defeat the powered-up Titan Pokémon, which will be fully healed and have twice as much HP as normal in this phase. Once they are defeated, they can be re-battled and caught as Former Titans at the location they were originally encountered.
The Titan Pokémon are battled at the same level and using the same move set each time, including as Former Titans. Former Titans have fixed natures and will have 30 IVs in every stat. If the Titan has two types, its Tera Type will be randomized between its two base types.
The False Dragon Titan includes three battles, instead of two. Once the player finds Titan Tatsugiri, a Dondozo will suddenly appear and swallow the Tatsugiri, and a battle against Dondozo immediately begins. Once Dondozo's HP is low, it will retreat to its Herba Mystica location, where the player must battle it again, teaming up with Arven. Dondozo does not have stat boosts from Tatsugiri's Commander Ability in either of these battles. Once Dondozo is defeated, Titan Tatsugiri will reappear and battle; the player's party will be healed and their Tera Orb restored before this battle.
Because Dondozo is not the true Titan Pokémon, only Former Titan Tatsugiri can be re-battled and caught. Former Titan Tatsugiri always has a Quiet nature.
Carmine will join the player to help fight the Titanic Loyal Three, which grew in size after being fed Kitakami Mochi by the villagers at Kitakami Hall. Her team stays the same between all three battles, only changing based on whether or not the player has completed The Way Home. These Titanic Pokémon have four times their standard amount of health.
Okidogi guards the Cornerstone Mask, and can be found at Paradise Barrens. At the beginning of battle, it will receive a two-stage boost to its Defense. The first time the player's Pokémon ends a turn below half health, Ogerpon will cheer and provide both teammates with a one-stage boost to Attack.
Munkidori guards the Wellspring Mask, and can be found next to Wisteria Pond. At the beginning of battle, it will receive a two-stage boost to its Special Defense. The first time the player's Pokémon ends a turn below half health, Ogerpon will cheer and provide both teammates with a one-stage boost to Special Attack.
Fezandipiti guards the Hearthflame Mask, and can be found on the east side of Oni Mountain. Upon being spotted, it will retreat into a nearby cave, and the player must follow it down through the cave to its other exit, overlooking Fellhorn Gorge where the battle will take place. At the beginning of battle, it will receive a two-stage boost to its Speed. The first time the player's Pokémon ends a turn below half health, Ogerpon will cheer and provide both teammates with a one-stage boost to Speed.
In all languages of the games except English and Chinese, the same terms are used to refer to both Titan Pokémon and Totem Pokémon.
The Japanese term for Titan Pokémon (Japanese: ヌシポケモンLeader Pokémon) is fully written in katakana, distinguishing it from Totem Pokémon (Japanese: ぬしポケモンLeader Pokémon), but the two terms are otherwise identical, being pronounced the same and having the same meaning.
