Provided you've challenged Ho-Oh to a battle in Pokémon SoulSilver and caused it to faint and then you ended up saving the game after the fact then you can head over to the Indigo Plateau in the Kanto region and go into the Pokémon League building in order to challenge the 4 Elite 4 Pokémon Trainers as well as the Pokémon League Champion, Lance. Once you defeat Lance, his defeat will activate the regeneration system that will allow all one-off Pokémon that have been KOed such as Entei, Ho-Oh, Suicune, Lugia, Articuno, Mewtwo and Raikou among others to regenerate in the wild with the exception of Suicune because it will regenerate in the Burned Tower.
Nothing, you just can't catch him.
it wil never come back...
Once you kill Tornadus, you have two chances. Since it is a legendary Pokemon, there is only one of its kind, and will appear after the first one.
Well technically, you can't KILL a Pokemon. You can just make it faint. When you make a legendary Pokemon faint, it will be gone until you start a new game.
I'm pretty sure they go away permanently if you kill ANY type of legendary pokemon. well when i killed tornadus a few days later it came back
you cant kill people on Pokemon!!!!!!
If you have killed him ... your f*cked, sorry :(
if you kill Lugia in Pokemon soulsilver you can re-match him after you beat the elite four.
You go off and train it and start defeating the gym leaders
No, and SoulSilver DOES have Ho-Oh. If you consider yourself a Pokemon fan, please kill yourself, because you aren't
You can find Ho-oh by taking the left path in Island #8. Pack some balls and potions Save first before fighting with Ho-oh then you can fight with it but be careful not to kill it or just use the masterball, that ball catches any pokemon without fail. Jean:)
nothing
If you kill azlef, It will FNT. so... save while you are in the cave.

In platinum it would be better not to kill mesprit uxie and azelf, it would be better to catch them.
