In Bell Tower after you have the Ecruteak City Badge and the Rainbow wing. Also you must have defeated the Elite 4. However, it's like a maze and it's hard to get to the top so go to YouTube and look up a video to catch HO-OH.
You can catch Hoho at night.
no
nowhere.. its impossible youd have to trade from leafgreen or firered or soulsilver and heart gold
the elite four.
no you can not, you can only get ho-oh in Pokemon heart gold or soul silver, or you can get it in global trade.
It depends. If it is on Gold, Silver, Firered, leafgreen, or emerald, then no. If it's on Soul Silver or heart gold, then I think it reappears at the tower after a week.
master ball.
i catched him with 7 badges on gold with a pokeball you have to have a rainbow wing (gold you have to get to the top of radio tower)(silver you have to get to pewter city) after you fly or travel to tin tower go to the top and he will be waiting for you and the easiest way to catch him is by master ball
You can't catch Arceus in Pokemon heart gold. You must bet it from Pearl, Daimond, or Platinum.
you don't.....you trade them......
Heart gold I think so gold no
You cant
