Or you can use the setwildbattle command like how other legendaries are battled. I'll provide an example later on.
What i mean is that
1. when i battle that pokemon an i kill that pokemon i can still fight it again.
2. when i was lost with that pokemon i can still fight it again.
3. when i captured it the pokemon will vanish forever.
you see i can't understand well the tutorial part of "compare".
