Catch an Ultra Beast After Defeating It

Prepare Your Beast Ball in Advance

To catch the boss after your team defeats it, you must have a Beast Ball in your inventory *before* the fight ends. The mod will prompt you with a catch option only if you're holding one.

Before joining the battle:

• Obtain a Beast Ball through crafting, trading, or other mod mechanics
• Keep it in your main inventory (not in a storage box or Pokémon)
• Make sure you have an open slot in your Pokémon team if you want to actually catch it

Complete the Catch After Victory

Once your group defeats the Ultra Beast:

• A prompt will appear asking if you want to use your Beast Ball
• Accept the prompt to attempt the catch
• The boss will be added to your team if successful
• If you don't have a Beast Ball or decline, the boss simply faints and you receive standard rewards instead

Note that catching is optional—you'll get rewards either way. Multiple players can attempt catches simultaneously, so coordinate with your team if you all want the same boss.
