Viridian Gym
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."
vs. Giovanni
Giovanni's Pokémon
Rhyhorn Lv45
Rhydon Lv50
Dugtrio Lv42
Nidoqueen Lv44
Nidoking Lv45
Giovanni's Pokémon "Pikachu Version"
Rhydon Lv55
Dugtrio Lv50
Persian Lv53
Nidoqueen Lv53
Nidoking Lv55
Giovanni's Strategy
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.
Route 22
After defeating Giovanni at the Viridian Gym, battle your rival on Route 22.
Win against your rival and proceed to the Pokémon League.
Victory Road
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.
Indigo Plateau
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
Lorelei's Pokémon
Dewgong Lv54
Slowbro Lv54
Cloyster Lv53
Jynx Lv56
Lapras Lv56
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.

Hitmonlee Lv55
Hitmonchan Lv55
Machamp Lv58
Key Points for Bruno's Battle

Battle with Psychic-type or Flying-type Pokémon.
E lite Four Agatha Battle
Agatha's Pokémon
Gengar Lv56
Arbok Lv58
Golbat Lv56
Haunter Lv55
Gengar Lv60
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
Lance's Pokémon
Gyarados Lv58
Dragonair Lv56
Aerodactyl Lv60
Dragonair Lv56
Dragonite Lv62
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.
