* Ho-Oh is a legendary Pokémon: Legendary Pokémon like Ho-Oh have extremely low catch rates, meaning they're incredibly difficult to capture.
* Poké Balls are ineffective: Regular Poké Balls are simply not powerful enough to have a good chance of catching a legendary Pokémon.
Here's what you need to do to increase your chances of catching Ho-Oh:
1. Use a Master Ball: The Master Ball is a guaranteed catch. You get one at the beginning of the game, so save it for Ho-Oh.
2. Weaken Ho-Oh: The lower Ho-Oh's HP, the higher your chances of catching it. Aim to bring it to as low HP as possible without knocking it out.
3. Status Ailments: A status ailment like sleep or freeze will further increase your chances of capture.
4. Use the best Poké Balls: Ultra Balls, Great Balls, and even Dusk Balls (if it's night) are much better than Poké Balls for legendary captures.
5. Increase your catch rate: You can equip your Pokémon with the "Catch Rate" ability or items like the "Shiny Charm" to further boost your catch rate.
Remember: Even with all of these strategies, catching Ho-Oh is still a challenge. You'll likely need a bit of luck on your side.
