Apply a Mega Evolution to Your Pokémon
During Battle
The most straightforward way to Mega Evolve is during combat. When your Pokémon is active in battle and you have the corresponding Mega Stone in your inventory, the option to Mega Evolve should appear in your battle menu. Select it to transform your Pokémon into its Mega form, gaining stat boosts and potentially new moves or abilities.
Using the Command
If you obtain a Mega Stone outside of normal crafting—through trading, commands, or creative mode—you can manually apply it using /msd apply mega msdextramegas:<mega name>. Replace <mega name> with the specific Mega Evolution you want (for example, msdextramegas:torterra for Mega Torterra). Your active Pokémon will receive the Mega Evolution.
Important Notes
Mega Evolutions are temporary and only last during battle. Your Pokémon returns to its normal form once the battle ends. You'll need a fresh Mega Stone for each transformation, so plan your stone crafting accordingly.
