In the original Pokémon Red and Blue versions for the Game Boy, you can find and catch several Legendary Pokémon, each with its unique location and method of capture. Below are the details for finding and catching Articuno, Zapdos, Moltres, and Mewtwo: ### Articuno - **Location:** Seafoam Islands - **Method:** Navigate through the Seafoam Islands by using moves like Strength and Surf to alter water currents and access new areas. Articuno is located at the lowest level of the cave. Be prepared for a tough battle, and use Ice-type counters if possible. - **Capture Tips:** Weaken Articuno using super effective Electric or Rock-type moves and then use Ultra Balls for a higher chance of capture. It's also helpful to inflict a status ailment like Sleep or Paralysis to make capture easier. ### Zapdos - **Location:** Power Plant - **Method:** After obtaining the ability to Surf, travel to the Power Plant from Route 10. Within the Power Plant, navigate your way through various Electric-type Pokémon until you encounter Zapdos. - **Capture Tips:** Similar to Articuno, weaken Zapdos with super effective Rock or Ice-type moves, use status ailments to your advantage, and throw Ultra Balls for a successful catch. ### Moltres - **Location:** Victory Road - **Method:** While making your way through Victory Road on your journey to the Pokémon League, you'll encounter Moltres. Ensure you have strong Pokémon on hand as this dungeon is filled with tough trainer battles and wild Pokémon encounters. - **Capture Tips:** Lower Moltres' HP with super effective Rock or Water-type moves, utilize status conditions to make catching it easier, and use Ultra Balls or even the Master Ball if you've saved it. ### Mewtwo - **Location:** Cerulean Cave - **Method:** Mewtwo is available only after you have defeated the Elite Four and obtained the National Dex. You can then access Cerulean Cave north of Cerulean City by surfing across the water. Mewtwo is deep in the cave and is one of the toughest Pokémon to capture. - **Capture Tips:** Mewtwo is at a very high level, so it's crucial to have a strong team. Use Dark or Bug-type moves to chip away at its health, inflict a status ailment like Sleep or Paralysis, and then throw Ultra Balls to capture it. The Master Ball is ideally used here, as Mewtwo is the most difficult Legendary to catch. ### Notes - Save your game before attempting to battle any Legendary Pokémon. If you accidentally knock them out or run out of Poké Balls, you can restart and try again. - Ensure you have a good stock of Ultra Balls and healing items, as these encounters can be lengthy. - Utilize status effects such as Sleep or Paralysis to increase the odds of capture. - Remember that the Master Ball has a 100% catch rate, so you may want to reserve it for the toughest catch, typically Mewtwo. ### Mew You mentioned "Mew" in your question as well. It's worth noting that Mew is not officially obtainable in the standard gameplay of Pokémon Red and Blue. Mew was typically distributed through special Nintendo events. However, there is a well-known glitch in the game, often referred to as the "Mew Glitch," that allows players to encounter and catch Mew. Since it is a glitch, it was not an intended part of the gameplay, and using such methods should be done with understanding that it may affect game stability. By following these instructions, with patience and preparedness, you will be able to capture all of the Legendary Pokémon in Pokémon Red and Blue. Good luck on your journey to become a Pokémon Master!
