You have to flirt with them first.
you capture the ledgon dariy Pokemon
you simply defeat the gym leaders in the johto and kanto regions
Go to Mt.Silver and beat Red.

You can't. There is no way in Pokemon Gold, Silver, or Crystal to re-battle the gym leaders. The only Pokemon game that I've seen this in is the 3rd gen games (RSE).
To get a Master Ball in Pokemon Crystal you have to defeat all the gym leaders then talk to professor elm. I advise you to keep the master ball for luigia.
There are 8 gym leaders in Pokemon lake.
After you have defeated all 8 gym leaders, go to prof. elm. He will give you the masterball.
the only problem is you cannot catch a gym leaders Pokemon !!!!
Beat all the gym leaders.
There are different types of gym leaders and each gym leader has a different pokemon type.
You cannot rebattle Gym Leaders.
