Pokemon Soul Silver Requests [ NDS ]
Secret - Beating Red (also Masterball location):
Here are a few tips for kicking Red to the curb.
1. Get a Shuckle. Having this guy out can be very handy. The insane defense and SP. defense make Shuckle a good Pokemon to have on the field when you are healing your team.
2. Have a Toxic user. Sure Red has several Full Restores, but Toxic can still help out a lot.
3. Have high levels. Red's levels are in the high 80s, so make sure your Pokemon are level 60 or higher.
Hope this helps!
