Here are a few examples:
* Pokémon Essentials: This mod focuses on catching and battling Pokemon in a way similar to the mainline games.
* Pixelmon: This mod is widely popular and aims to provide a complete Pokemon experience within Minecraft, including catching, battling, breeding, and even trading.
* PokeCraft: This mod focuses on adding Pokemon as companions and allows you to build Pokeballs and use them to catch Pokemon.
These are just a few examples, and there are many other Pokemon mods available. You can find them on websites like CurseForge and Minecraft Forge.
However, it's important to note that these mods are unofficial and may not be as polished or bug-free as official Minecraft content. You should always install mods at your own risk, and make sure you back up your Minecraft world before installing any mods.
