Mt. Silver

Becoming Champion is not the end. Two trainers are still stronger than you.

The story

1. Find Professor Oak. A fierce heat blocks the Mt. Silver entrance in the Thor Volcano thor_v01. Only Indigo League Champions may pass. Professor Oak is waiting at the base.
2. Battle Blue. Oak sends you after his grandson, your rival, who is training at the dojo.
3. Enter Mt. Silver. After you beat Blue, the old cave entrance in the frozen depths of the ice dungeon ice_dun03 opens for you.
4. Battle Red. He waits at the very top.

Blue and Red

Both are double battles with a team of six each, sent out two at a time, with a 20 minute time limit.

Trainer	Requires	Team	Level
Blue	Champion title	Alakazam, Rhydon, Exeggutor, Gyarados, Pidgeot, Arcanine	95-99
Red	Victory over Blue	Pikachu, Snorlax, Venusaur, Espeon, then two Mega Evolutions	95-99

Both give a special prize the first time you win, and can be rematched once per day for rewards.

After Red

Beating Red completes the story, and it is also what lets you try to catch the Mythics during Mythic raids.
