LV 45
lugia is level 45.
Lugia learns Sky Attack at level 99.
The only way you can get a Level 3 Lugia in "Pokémon SoulSilver" is by using a cheating device such as an Action Replay or Pokésav.
Lvl 45 If You Have Soulsilver. If You Catch Him In Heartgold He Is Lvl 70.
HeartGold: Lugia lv 70; Ho-oh lv 45 SoulSilver: Lugia lv 45; Ho-oh lv 70
Ditto and Lugia do not breed. I tried it.
As of right now the answer is yes because it's the same as Gold, Silver and Crystal were. Yes, you can. If you get HeartGold you encounter Ho-oh at level 45 and Lugia at level 70. If you get SoulSilver you get Lugia at level 45 and Ho-oh at level 70.
Lugia is located in the whirl islands
No. Lugia for SoulSilver and Ho-oh for HeartGold. Yes, you just get them at different times. You get Ho-oh in Johto and Lugia in Kanto in HeartGold, and vise versa in SoulSilver.
On whirl island
yes you can. but if you have Pokemon soulsilver, the first encounter will be a lugia and vice versa for ho-oh.
I recommend Soul Silver because Lugia is Psychic and flying and can use water moves to destroy ho-oh and I like Lugia Better. While Lugia DOES have the type advantage, if you get Heart Gold, you get Lugia later on anyway, AND it's a level 70 instead of level 40.
