From Bulbapedia, the community-driven Pokémon encyclopedia.
A Pokémon that is a trio master is one who, in some way, oversees a legendary trio of Pokémon.
The trio master and the trio itself may relate in different ways. For example, Lugia is the trio master of the legendary birds; it is the only one who can quell their fighting when Lawrence III captures one of them in The Power of One.
Catching trio masters
In the games, the trio master sometimes will require that the members of its legendary trio be caught beforehand.
In Crystal, Ho-Oh cannot be caught until all three of the legendary beasts have been captured.
Pokémon Diamond, Pearl, and Platinum
In Diamond, Pearl, and Platinum, Regigigas will not awaken unless the player has the legendary golems in his or her party. Conversely, an event Regigigas unlocks the legendary golems in Platinum.
Pokémon HeartGold and SoulSilver
In HeartGold and SoulSilver, Rayquaza is only obtainable after both Kyogre and Groudon have been obtained in the same game, an impossible feat without trading or cheating.
Pokémon Black and White
In Black and White, Landorus is only obtainable after both Tornadus and Thundurus have been obtained in the same game, also an impossible feat without trading or cheating.

- Arceus is the only trio master that is related to more than one legendary trio.
- Lugia and Regigigas are two trio masters who were not present in the same generation as their trio. Also, they were both introduced in the generation directly after the generation their trio was introduced. This also makes their trios the only ones who did not have a known trio master in the generation they were introduced in, then gain one later.
