u need 2 either catch groudon on soul silver and trade it onto heart gold yourself or u can find some1 else who has a groudon on soul silver and trade with them.
You get Groudon in Pokemon Heart Gold by trading with somebody who's found Groudon in Soul Silver. You can't find Groudon in Heart Gold, you find Kyogre. Soul Silver players find Groudon.
You have to trade it from soul silver to heart gold this is the only way
you can catch lugia ho-oh suicune raikou and entei latios on soul silver and latias on heart gold groudon on soul slver and kyogre on heart gold arcticuno zapdos and moltres hope this helps:x
In Heart Gold I don't think you can get Groudon (unless you trade). Instead though, I think you can catch Kyrogue - (although I don't know the exact location of where to find it). Hope this helps
yes but you need the groudon from soul silver along with a Kyogre that you catch in heart gold. he will be in the same area as kyogre. further questions are easier to look up on serebii.net
