trade
u cant
you cant
You can't, it must be traded from ruby, sapphire, or emerald.
Regirock, Regice, and Registeel (and for that matter, Regigigas) are unobtainable in Fire Red and Leaf Green.
You catch regice
Well... In FireRed and LeafGreen, you cannot actually catch Regice without using cheats. The only way to legitimately catch Regice is to have Sapphire, Ruby, or Emerald. In one of those games, you need to have a Wailord and Relicanth. You also need to know how to read Braille. You follow the instructions in the underwater cave southwest of Sootopolis. Then you simply go west of Petalburg, surf westward until you reach a cave. Inside, you follow the instructions and it opens up the path to Regice. It is at level 40 and is an Ice type, so be prepared. As it is a lengendary, it is significantly harder to catch than most pokemon, so bring a lot of ultra balls. I recommend putting it to sleep.
You cant get it anywhere in the game. If you want it, u should be playing Pokemon on the comp. and u gonna have to use the gameshark cheat. I think u can get it if u are playing on the gameboy but I dunno how?
You can find regigigas in the snowpoint temple, but you'll need regirock,regice,registeel to battle it, it will be at lvl70
there is not regice in pearl. but if you have ruby, emerald, or sapphire you could trade regice,regirock, and registeel to get rigigious.
Maybe but i would recomend that you used emerald, ruby, or Sapphire which is very easy because all you have to do is read the dots in the under ground cave and the rest is for you to find out love ya.
u don't get regice on Pokemon pearl
There was no regice on the iceberg Titanic hit.
