I don't think anyone else has asked this, but - I raised my Pokemon quickly early on and blew through the Gyms with my beggining Pokemon, then through the Elite Four with little help from Zekrom since it was rather weak when I got it. Anyway - I already defeated the Elite Four, and I accidentally caused a legendary Pokemon to faint when I wanted to capture it and put it away in a storage box. I did read that they reappear after the Elite Four or Pokemon League, right? Does this mean I have to re-battle and totally dominate them for a second time ooorrr am I out of luck with a reappearance and second chance at catching them?
I apologize for the long explanation and question. Thanks for any help.
