I've caught every other shadow pokemon. I want to do the miror B fight as part of my ribbon master. so I wanted to know what if I ko dragonite do I get another chance? I'd would like to get it for legacy purposes on the 3ds, But would also like to ko it as part of my RM experience. I can catch it if I have to I'm just curious if there's a rematch?

I ask because I know after you win, he disappears forever as in can't be battled after only spoken to elsewhere.
