It's not hard just damage the moltres that he has little HP left. And then use a ultra ball.
use a masterball
No, you don't. In Fire Red/Leaf Green you get Lapras in Silph Co.
I'm sorry dude but I don't think you can just migrate it from leaf green/fire red
Moltres, zapados, and articuno are the three main legendaries in leaf green/fire red
moltres is in leaf green and fire red not emerald.
i belive so my best friend transferred moltres, zapdos, etc from leaf green to platinum. i think you have to beat the elite four in one of the versions, maybe both and use migration. this might help you
in leaf green hes in mt ember ,in Pokemon ss and hg his in mt silver and in platinum you can find him randomly in the wild but he flees after the first move
If by that you mean Legendary Pokemon then the pokedex will let you have; Articuno Zapdos Moltres Mew Mewtwo Raiku Enti Suicoon Lugia Ho-Oh Celebi Regirock Regice Registeel Grudon Kyroge Raquiza But the only ones you can catch (that I'm aware of) are the 4 you can catch in Red/Blue/Green and Yellow; Articuno Zapdos Moltres and Mewtwo
Yes.
you really can't catch celebi in a Pokemon game without cheats
In Red, Blue, Yellow, Fire Red, and Leaf Green Moltres is in Victory Road. In Gold, Silver, Crystal, and Heart Gold and Soul Silver Moltres is in Mount Silver.
If you want a Moltres on Pokemon Emerald,you'll need to trade from Fire Red or Leaf Green. Or use a GameShark.
