What moves do lugia and ho-oh know when you catch them in heartgold or soulsilver?

Lugia and Ho-Oh, when caught in HeartGold and SoulSilver, do not learn any moves upon being caught. They start with a set moveset that is fixed and cannot be changed by leveling up or through TMs/HMs.

Here are their starting movesets:

Lugia:

* Aeroblast: A powerful Flying-type move with high accuracy and a chance to flinch the opponent.

* Extrasensory: A Psychic-type move that hits both physical and special defense.

* Psycho Boost: A powerful Psychic-type move with high power, but lowers the user's Special Attack after use.

* Thunder: An Electric-type move with a chance to paralyze the opponent.

Ho-Oh:

* Sacred Fire: A powerful Fire-type move with a chance to burn the opponent.

* Brave Bird: A powerful Flying-type move that deals heavy damage, but also damages the user upon use.

* Sunny Day: A move that summons harsh sunlight, boosting Fire-type moves and lowering Water-type moves.

* Holy Flame: A Fire-type move with high power.

These moves are all very powerful and are well-suited for their respective types, making Lugia and Ho-Oh formidable opponents even from the start.
