Catch Pokémon in Pokémon Red/Blue

Sometimes, you're down to one Poké Ball and a rare Pokémon may appear! You may panic and wonder, "How on earth will I be able to catch this?" This guide will explain some ways to counter this fear and increase the odds of catching Pokémon in Pokémon Red, Blue, and Yellow.

Steps

Weakening the Pokémon

  1. Weaken the Pokémon. Go to Items and choose Poké Ball. The trick is to get its health as low as you can without letting it faint. Use a combination of weak and medium power attacks to do this. See the numbers after each technique? These are called the Power Points or PP. Generally, the higher the PP, the weaker the attack.
  2. Use status ailments.
    • Poisoning or burning the wild Pokémon will cause its HP to gradually deplete, making it easier to catch, but increasing the risk of causing it to faint.
    • Putting it to sleep or paralyzing it are more reliable methods, however sleep only lasts a few turns and paralysis still allows it to fight back sometimes.
    • If you can freeze a Pokémon, you can catch a Pokémon very easily, because in Generation 1 (Red, Blue and Yellow) the only way to thaw a Pokémon is to hit with a Fire-type attack.

Glitch method

  1. Use this at your own risk. This only works in the original Pokémon Red, Blue, and Yellow versions.
  2. If you would like to render yourself a 100 percent chance of catching a Pokémon, take your Master Ball, if you still have it.
  3. Place it in the sixth slot of your inventory. Use Select to move the items around.
  4. Go to Viridian City and ask the old man who blocked the way in the beginning of the game to demonstrate how to catch a Pokémon.
  5. After the demonstration, fly to Cinnabar Island. Surf alongside the coast of the island. Soon, you may find glitched Pokémon called MissingNo, or 'M'.
  6. If you decide to catch it, then be careful! It will glitch the current Hall of Fame data at the very least. Upon encountering it, you will suddenly have 128 Master Balls.
    • The game uses glitch characters to show that the number is over 99.

Safari Zone

  1. Visit the Safari Zone in Fuchsia City. You are given Safari Balls, which have the same catching power as Great Balls.
  2. Use rocks to make Pokémon easier to catch, but they will become more likely to flee.
  3. Use bait to do the opposite. They will be less likely to flee, but they will also be harder to catch.
  4. If you catch a Tauros or a Chansey and raise it up, few enemies will stand up to you.

Tips

  • To save steps in the Safari Zone, walk to patch and tap button so you spin, but don't move. This only works in Yellow version.
  • A Great Ball is better than a Poké Ball and an Ultra Ball is better than a Great Ball. Keep in mind that the Great and Ultra Balls cost more money than regular Poké Balls.
    • Purchasing lots of these is an easier way to catch Articuno, Zapdos, Moltres and Mewtwo.
    • The Master Ball is the only Poké Ball that has a 100% catch rate regardless of circumstances. Only 1 can be obtained in the game.
    • There is a 1 in 65,536 chance that the Master Ball will fail. If this happens, we're sorry, the game hates you. Restart and try again if it happens.
  • Beat the Elite 4 a lot to get money for Poké Balls. Beware, however, that if you black out, you'll lose money, so save before battling and restart if you lose.
  • Use false swipe. Then paralyze it. Keep tossing ultra balls and hope for the best.
  • You don't have to catch a MissingNo. for the glitch to work. You can just encounter it and run.

Warnings

  • The Ghost Marowak in Pokémon Tower in Lavender Town cannot be caught. A Master Ball will not work here.
  • Not all Pokémon can be acquired by finding them in the wild.

Things You'll Need

  • A Game Boy, Game Boy Color, or Game Boy Advance + AA batteries
  • A Pokémon Red, Blue or Yellow cartridge
  • Poké Balls, Great Balls, Ultra Balls and/or (a) Master Ball(s).
