HeartGold/SoulSilver Legendaries

Raikou and Entei:
Raikou and Entei must be woken up in the Burned Tower in Ecruteak City before you can catch them. After that they will roam around Johto. Be sure to have a Pokemon with mean look in your party so them wont flee. To see their current location check the PokeGears map.


Suicune:
Like Raikou and Entei Suicune must be woken up at the Burned Tower. But instead of it roaming Johto it will be in fixed locations and you must find it. The locations in order are Cianwood City, the middle entrance to Mt. Mortar, Vermilion City, Route 14, and lastly by Bill's house on route 25. You will be able to capture it by Bill's house but if you fail to capture it you have to beat the Elite Four again and then go to the Burned Tower to capture it. I suggest saving before attempting to catch it.

Ho-oh:
If you have HeartGold you will be able to encounter Ho-oh after you beat Claire and get the Rainbow Wing from the Radio Tower's Director after you beat Team Rocket in Goldenrod City. Then you must beat the Kimono Girls at the Ecruteak dance theater to get the Clear Bell. Then you must climb Bell Tower and once you are at the top you will be able to fight and catch Ho-oh after the Kimono Girls summon it. If you have SoulSilver you must go to Pewter City and get the Rainbow Wing from a man there then climb to the top of Bell Tower and Ho-oh will be there. I suggest saving before attempting to catch it.

Lugia:
If you have SoulSilver you will be able to encounter Lugia after you beat Claire and get the Silver Wing from the Radio Tower's Director after you beat Team Rocket in Goldenrod City. Then you must beat the Kimono Girls at the Ecruteak dance theater to get the Tidal Bell. Then make your way to the Whirl Islands and get to where the Kimono Girls are at then they will Summon Lugia and you can battle and catch it. If you have HeartGold you must go to Pewter City and get the Silver Wing from a man there then get through the Whirl Islands and Lugia will be there. I suggest saving before attempting to catch it.

Articuno:
Articuno can be found in the Seafoam Islands after earning all 16 badges. I suggest saving before attempting to catch it.


Zapdos:
Zapdos can be found in front of the Power Plant after earning all 16 badges. I suggest saving before attempting to catch it.


Moltres:
Moltres can be found in Mt. Silver after earning all 16 badges. I suggest saving before attempting to catch it.


Mewtwo:
After obtaining all 16 badges make your way through the Cerulean Cave to get Mewtwo. I suggest saving before attempting to catch it.

Latias/Latios:
After you fix the Power Plant go to the Vermilion Fan Club then walk outside and Steven will inform you that Latias (if you have HeartGold) Latios (if you have SoulSilver)is roaming Kanto. Check your PokeGears map to see Latias or Latios's Location. You will need a Pokemon with mean look so it wont flee. I suggest getting a Lv 40+ Golbat from the Seafoam Islands and Lv a bit so it is faster than Latias/Latios.

Groudon/Kyogre:
After obtaining a Kanto starter from Professor Oak go to Mr. Pokemon's house to collect a Blue Orb (HeartGold) or a Red Orb (SoulSilver). Then head to the Embedded Tower on Route 47. Once inside you will fight and try to catch Kyogre if you have HeartGold or Groudon if you have SoulSilver. I suggest saving before attempting to catch it.

Rayquaza: Once you have both Kyogre and Groudon Professor Oak will give you a Jade Orb which will allow you to fight and catch Rayquaza int he Embedded Tower. I suggest saving before attempting to catch it.

Dialga, Palkia, and Giratina:
Fist of all to get any of these Pokemon you must have a Arceus.Once you have it put it first in your party and go to the Ruins Of Alph research center. Theb you will be taken down the Ruins and then transported to the Sinjoh Ruins. Go outside and talk to the hiker who will take you to Cynthia. Deposite all of your Pokemon into the PC besides Arceus and then go talk to Cynthia. You will then be given the choice to choose from a lv 1 Dialga, Palkia, or Giratina. Choose wisely.
