Pokémon Red and Blue/Walkthrough

'You are about to begin the StrategyWiki walkthrough for Pokémon Red, Blue & Yellow, from the first step of your journey in Pallet Town to the final battle that will prove once and for all who is the world's greatest Pokémon Trainer. Pokémon is a deep and complicated game, and each page is packed with as much useful information as possible. Before you begin, please take a few minutes to read through this section.'

''Because of the sheer amount of information included on each page, special attention has been paid to the layout of the tables and images in this guide. It is recommended that you view this guide with a minimum desktop resolution of 1024 × 768, or higher if possible. Maximize your browser as wide as possible in order to see the pages the way they were intended. Some pages will simply not display correctly in smaller widths.''

Local Maps
You will find a map of each area of the game in that area's section. In the cases where they are too wide, they have been shrunk to allow room for other useful information. If a map has been shrunk and there's not enough detail for you to make something out, click on the map for an expanded view.

Pokémon Profiles
As new Pokémon become available, you'll find little profiles on them. These profiles aren't designed to give you background on the Pokémon or anything, just to give you an evaluation of whether they're worth using, and maybe some tips on how to use them correctly. Bear in mind that you may find certain Pokémon to be more useful than what the profiles say, so don't take them as an authority, but as a suggestion.

Pokémon that are only available in Blue (such as ) have blue borders, Red-only Pokémon have red borders, and Pokémon that only Yellow players can get at the point shown have yellow borders. If they appear in multiple versions, the border is lavender.

Newly Available Pokémon
Somewhere towards the top of each section, you'll find a table that illustrates which new Pokémon you'll be able to acquire in that area. These tables only list Pokémon when it's your best opportunity to get them in each version, and only list each Pokémon once. If you catch all of the Pokémon shown in these tables, at the end of the game you'll have every single Pokémon that's possible to catch, trade for, buy, or earn in your version of the game. The one exception is evolved forms, which aren't listed, since it's usually easiest to get those by leveling up your Pokémon from their base forms.

Junior Trainer Data
As you progress through the various Routes and dungeons, you'll run into a variety of Junior Trainers and bosses you will challenge you whenever you cross their line of vision. To help you determine whether it's a fight you can win, or even a fight worth fighting, each trainer's name, bench, and the amount of money they hold is listed either to the side or below each map. The Pokémon that exist in every version are in lavender, the ones that are only in Blue/Red are in purple , and the ones that are only in Yellow are, of course, yellow.

Pokémon Finder
The probability of running into certain Pokémon varies wildly from area to area, and version to version. The percentages listed here roughly reflect how much work each Pokémon is going to be to get in each version. (The colour of the border around the number indicates which version of the game is being represented. They always appear in the order: Red, Blue, Yellow.)

If the name of the Pokémon is in blue instead of red, that means the numbers reflect the odds of running into Pokémon while you're using Surf to walk on water.
