There is no Groudon in Pokémon Crystal.
Actually you will not be able to find a Groudon in pokemon black or white. It's because you will not be able to find a Groudon in the wild. The only way you can get Groudon in pokemon black and white you will have to trade with someone who has a Groudon or you can use Global trade.
Groudon is unavailable in heartgold. You can only catch Kyogre. If you want groudon, you will have to trade from heartgold, or migrate from another game.
Wailord is the largest Pokemon followed by groudon.
Groudon can be found at: Cave of Origin, Terra cave.
no, ditto cannot breed withe legendarie pokemon.
No, the only legendary pokemon that can breed with a Ditto is Manaphy, to make the pokemon Phione
Not quite, but almost anything. Legendary pokemon, like Groudon, Kyogre and what-not, no. Most pokemon you can, and the pokemon egg will hatch into the first evolvement of the pokemon that isn't a ditto. But if the pokemon is a legendary pokemon, even if it isn't genderless like Latios or Latias, it can't breed with a ditto. So, generally, in Ruby/Emerald/Saphire, the ones that can't breed with a ditto are:Regirock/Regice/RegisteelLatias/LatiosKyogre/Groudon/RayquazaJirachiDeoxys.Hope I helped! :)
