Challenge the Gym Leader Giovanni in the back.
Basically, you can smoothly progress using type-matching moves of Venusaur, Blastoise, Lapras, and Articuno.
Watch out for slow Pokémon like Snorlax, as they might get hit by "Fissure."
If using Pokémon like Snorlax or Slowbro, keep their levels high to a void getting affected by "Fissure."
Giovanni's Pokémon "Pikachu Version"
In Red, Blue, Green, Ground-type moves can easily defeat them, but in Pikachu Version, Persian is added instead of Rhydon.
Persian is a Normal-type Pokémon and has high speed.
Use moves like "Thunder Wa ve" to lower its speed or defeat it quickly with a fast Pokémon.
After defeating Giovanni at the Viridian Gym, battle your rival on Route 22.
Win against your rival and proceed to the Pokémon League.
Inside Victory Road, you need the HM move "Str ength" to solve puzzles.
It is inhabited by Pokémon like Machop.
Be cautious of high-level Pokémon battles, and keep an eye on HP and PP.
Once you've prepared at the Pokémon Center and Friendly Shop, challenge the E lite Four.
Here, even with a decent level, knowledge of type matchups becomes essential.
Fire-type is strong against Water-type, and Electric-type is strong against Water-type.
Water-type is strong against Dragon-type, and Ice-type is strong against Dragon-type.
Grass-type is strong against Fire-type, and Rock-type is strong against Ice-type.
Electric-type is strong against Dragon-type, and Ice-type is strong against Dragon-type.
Progressing while replenishing type matchups makes the journey easier.
Before challenging the E lite Four, capture Articuno and Zapdos.
In this game, especially Articuno is outstanding.
The move it can use, "Blizzard," has a power of 120, an accuracy of 90, and only 5 PP, but it has a 30% chance of freezing the opponent.
The frozen status, according to the mechanics of the first generation, won't be lifted unless hit by a Fire-type move, essentially equivalent to defeating a Pokémon.
Due to the challenging balance of the first generation battles, which is harsher than the current Pokémon environment, the battle balance was largely revised in Gold/Silver and Ruby/Sapphire.
E lite Four Lorelei Battle
Key Points for Lorelei's Battle
Lorelei's Pokémon ha ve high physical resistance, and battles can extend if hit by moves like "Sing" or "Minimize."
Using "Toxic" against all but Dewgong makes the battle easier.
With many Water-types, use Thunder with Zapdos to defeat them quickly.
E lite Four Bruno Battle
Key Points for Bruno's Battle
Bruno is a Fighting-type specialist.
Although he has two Rock-type Pokémon for Flying-type covera ge, Onix's attack power is not significant.
Battle with Psychic-type or Flying-type Pokémon.
E lite Four Agatha Battle
Key Points for Agatha's Battle
Despite the impression of being a Ghost-type specialist, Agatha is a Poison-type user.
Overall, the speed is high, and there are scenes where Gengar's two HP reduction moves can be problematic.
It is the most challenging part of the E lite Four, and starting with moves like "Agility" from Pokémon like Zapdos or Articuno is safe.
When there's an opening, use Chansey to endure while healing with "Potion."
E lite Four Lance Battle
Key Points for Lance's Battle
The battle changes depending on the player's actions at the beginning.
After defeating Agatha and placing Articuno at the front of your party, write a report at Agatha's location, proceed to Lance's room, and freeze Gyarados with "Blizzard."
Increase the sweeping performance of the entire party while raising Speed and Special Attack with "X Special," "X Speed," and "Agility."
Once Speed and Special Attack are sufficiently raised, defeat one Gyarados with Articuno.
As for Dragonite, it can be defeated with an Ice-type move, so while Gyarados is frozen, raise Articuno's Speed.
