Too many wild pixelmon spawned, how can I kill them?

Due to excessive use of spawn boxes, too many wild pixelmon are walking around in my local game. This is slowing down the game to a crawl.

Is there an operator command to kill them easily and get the game back in a playable state?

Version is Forge 1.7.


Solution 1:

I assume Pixelmon are registered as standard entities. If this is true, you can run /kill @e to kill all entities in the world.
