What is after the Johto elite four?

Question

After the Elite four, most people go and start again in Kanto, but I want to complete everything in Johto first. This doesn't mean train, it means explore as much as I can. But is there anything I need before doing this?
I know if I want to catch the other legendary, I need to go to Kanto first. What can I do in Johto without going to Kanto?

Answer 1

With the help of the source and my knowledge:

• Get a Tyrogue! This is a rare Pokemon to get, which is why its so exciting. I'm unsure if you need Rock Climb for this, but if you do, ignore this... but deep in the bowels of Mt. Mortar you can meet the guy who previously owned the Dojo in Kanto. If you battle him successfully, you will get a Tyrogue if you have free space.

• Be the best Pokeathlete out there! Yeah, you can get your Pokemon and get to the fonal room of the Pokeathlete Hall of Fame. It's cool cos when you do that, you gwt to verse a few familiar faces. ;)

• Catch Entei, Raikou and Suicune! Yeah.

There are probably more I'm forgetting, but just remember that you can always fly back to Johto and do what you want to do. There's nothing you actually need to do; just fly to New Bark, get an SS Anne ticket, fly to Olivine City and sail to Vermilion!

Hope I helped. :)

Do you mean Pokéathlon? This feature is only available on HGSS.

Answer 2

Visiting Kanto is the postgame in those games.

Every Pokemon game has some sort of postgame, but they tend to differ. Visiting Kanto is the postgame for G/S and HG/SS.
