you can't get ho-oh in Pokemon platinum only by cheating with AR or r4 or migrate it of Pokemon gold
you need to migrate it from one of those original games
You can catch Hoho at night.
trade from hg/ss or migrate from fire red/leaf green otherwise its impossible without cheating.
no
the elite four.
master ball.
You must trade it from Emerald, FireRed, or LeafGreen versions.
you don't.....you trade them......
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
It is Ho-Oh and you cannot catch it on a gameboy you need an emulator on a PC to catch it and even with that you need cheats.
you can't catch him in platinum but in soulsilver or heartgold you can catch him then trade it to platinum.
With some kind of pokeball. Maybe you should have asked how to find/get to ho-oh instead and not how to catch it.
