Why HMs can't be removed:
* Gameplay Requirement: HMs were designed to be essential for navigating the game world. They often open up new areas, solve puzzles, or allow you to progress the story.
* Permanent Learning: In most games, once a Pokemon learns an HM, it can't forget it through normal means (like using a Move Deleter).
What you can do instead:
1. Teach it to another Pokemon: If you have another Pokemon that doesn't need the HM, you can teach it to them. This frees up the move slot on your primary Pokemon.
2. Use a "HM Slave": Some players dedicate a specific Pokemon to learning all the HMs, leaving their valuable moveslots open on their main team.
3. Use a specific item: In some games, like Pokemon Black and White, you can use the "TM Case" to remove HM moves from Pokemon. However, this is a rare case.
4. Utilize "HM Cut" (Generation 6 and later): Some games allow you to learn an alternative move called "Cut" that fulfills the same purpose as the HM Cut. This allows you to remove HM Cut from your Pokemon and replace it with a more useful move.
Important Note: The ability to remove HMs varies greatly depending on the specific Pokemon game you're playing. Always consult the game's guide or online resources to see what options are available.
