What to do after beat misty SoulSilver?

Answer 1

1. After beating Misty, be sure to grab the Machine Part that's in the red and white inner tubes, located inside the upper-left part of Misty's gym.
2. Head back to the Power Plant by Surfing down Route 10 and give the Part to the Power Plant Manager.*
3. Go to Lavender Town and upgrade the Radio feature on your PokeGear.
4. Go back to Vermillian City and head east to find the sleeping Snorlax; wake him up using the PokeFlute on your new, upgraded Radio on the PokeGear. Warning: When he wakes up, he'll attack you.
5. Head inside Diglett Cave. Warning: Some Digletts/Dugtrios have the ability Arena Trap- meaning you won't be able to run away from them. However, they're pretty weak so it should be no problem.
6. After making your way through Diglett Cave, go north. You'll reach Pewter City. Brock, the Pewter City Gym Leader, is the next gym leader you'll have to face.
7. Once beating Brock, go back south, run through Viridian, and finally reach Pallet Town.
8. Surf down to Cinnabar Island. You'll see Blue, who will challenge you in Viridian once you have 7 Kanto badges (not Johto!).
9. Enter the Seafoam Islands and make your way through. You'll find Blane's new gym. When you beat him, go back and talk to Blue, who will go back to Viridian's Gym.
10. Beat Blue. Prof. Oak will call you. Go to Pallet Town and he'll give you Rock Climb (very helpful. Now you can explore all those places you couldn't before! Cliff Cave, Rock Cave, etc.).

After all this, a couple things are unlocked:

• Mt. Silver
• Moltres
• Articuno
• Zaptos

*Once you've gotten this far and done everything mentioned prior, Suicune will appear at Route 25 and will STAY THERE. Finally, you can battle and, if you want, capture Suicune! Eusine won't even get in your way this time!
