#245 Suicune

Suicune is somewhat different to the other Legendary Beasts in that it does not roam Johto in the manner Entei & Raikou do. Instead, it is a stationary legendary. However, before you can get it, you must chase it around. At some points in the game, you will meet Eusine and he will follow you as he is also tracking Suicune. Suicune, like Entei & Raikou is released into Johto when you access the basement of the Brass Tower.

Suicune is seen in the following places and you must follow it if you wish to capture it. First, it will be found in the north of Cianwood City. After you encounter it there, you will shortly find it outside the entrance of Mt. Mortar in Route 42. Once you find it here, it will leave Johto and head to Kanto where you will see it in Vermillion City soon after you arrive. Next you will see it in Route 14 where it will escape for the final time to be found outside Bill's House in Route 25 after Misty has returned to her gym. This is where you battle Suicune.

If you defeat it and don't capture it, it will re-appear at the Burnt Tower when you beat the Elite Four

Rayquaza is a legendary Pokémon whom you'll have the most trouble getting. To get Rayquaza, you have to take the Jade Orb to the same cave you obtained Kyogre or Groudon within.

This includes the one you captured in your game and one you obtained in a trade, but captured within the Heart Gold or Soul Silver game only. Once you have these two Pokémon, go to Professor Oak and show them to him. He will give you the Jade Orb. With it, just go to the Embedded Tower and Rayquaza will appear
