Use HeartGold or SoulSilver. You can catch both in one game.
Assuming you mean Ho-oh or Lugia, Lugia would win because he's a Psychic type and could control Ho-oh. And if you mean Hoho junk food, Lugia would still win.
you don't.....you trade them......
If you are talking about Hoho, Lugia, etc... then you will need a cheat.
you get the wing of the hoho in soulsilver and the wing of lugia in heartgold
Yes. You will be able to find Hoho on top of the bell tower after you have the rainbow wing and the clear bell and you can get lugia too
i don't know who would win lugia has a higher defence but ho-oh has a higher attack
you have to migrate or use action replay
i say they are same because lugia has more speed then ho-ho but ho-ho has more power and lugia also lugia better looking but does not matter of the looks
trade from hg/ss or migrate from fire red/leaf green otherwise its impossible without cheating.
You can get Lugia from playing Pokemon XD and Ho-Oh from playing Pokemon Collesium. Then you can trade them from there to Sapphire and then move them to the Pal Park in Diamond.
I'm Very Sorry but you can't. You have to Migrate from Ruby, Sapphire, Fire Red, LeafGreen, or Emerald. And if you don't want to Migrate or trade from somebody that has a Lugia it's obtainable with the AR Code
you need to migrate it from one of those original games
