After becoming the Pokemon League Champion of Kanto, new Master Trainers will begin to appear around the region. These are very powerful Trainers that specialize in one species of Pokemon. Challenge them to a battle using the same Pokemon without using any items (Mega Stones are an exception), or show them the Pokemon they ask for at a certain CP level to earn a new title. For example, if you defeat the Charizard Master Trainer, you will display the ‘Charizard Master’ title every time you trade, battle with a real person, or heal at the Pokemon Center. This title can be changed by speaking with one of the Game Freak staff in the Game Freak office of the Celadon Condominiums.
Defeat six Master Trainers to gain the ability to battle Pokemon Trainer Red at the Indigo Plateau. He will be waiting outside the front doors. Defeat Red to earn the title ‘Battle Master.’ Once you defeat all Master Trainers in the game, you will receive the title ‘Grand Master’ from the Game Freak office in the Celadon Condominiums.
Make sure to increase your Pokemon’s stats with candies or they won’t stand much of a chance even at a higher level than your opponent. I will list a few tips in the table below. Feel free to share more tips in the comments section!

Route 23, north near the Indigo Plateau
Lv 75; Moves: Protect, Thunder Punch, Dragon Pulse. Charizard will use Protect as its first move to see if you will use a Mega Stone. If you evolve to Mega Charizard X, your opponent will use Dragon Pulse. If you evolve to Mega Charizard Y or don’t mega evolve at all, your opponent will use Thunder Punch. You can do nothing for the first move, then evolve to Mega Charizard X and use Rock Slide or Thunder Punch to deal massive damage while receiving little in return. A second attack should put him down before he can knock out your Charizard.

Route 16, near Celadon City
Lv 75; Moves: Reflect, Facade, Rest. Use Reflect to increase your Snorlax’s defense. He will do the same for the first turn and every time it wears off. Next, use Brick Break to take down his reflect and deal 2x damage. Another option is to use Crunch to deal damage and possibly make him flinch, but this option is only if your Snorlax is faster than your opponent. Once the opponent’s HP is in the lower orange or red, he will use Rest to fully restore his health and status condition. Try to knock him out before that happens, but do not use status conditions or his Facade will deal massive damage. You can use Body Slam while he’s sleeping to deal more damage than Facade, and he will not get a status condition while asleep.
