you cant fight it again
It should come back after you beat the Pokemon league or if you saved b4 battling Cobalion which most people do you can just turn off the ds/ds lite/dsi/dsi Xl and battle him
Pokemon Are Not Evil they just faint the opjectson of the game is to beat the champion in the Pokemon league
Go to Mistralton Cave and Cobalion will be there waiting...he is lvl. 40-42. Thanks for reading -VOID
Yes, you beat the Pokemon League first.
well there are two ways one you can get a really powerful Pokemon and second battle the league and hope for the best. I recommend at least 15 full restores and at least 10 revives because your Pokemon will faint and get low on hp.
Beat them again
Yes, if you have KOed Cobalion and have already saved your game then you need to defeat the Elite 4 in order to activate the respawning system so that the game will return Cobalion.
The Pokemon League is basically the point of all the Pokemon adventure games. It has the Elite Four (and your rival) which are the most skilled trainers in the Pokemon world and if you beat them, you can call yourself the Pokemon Master. You must face the Elite Four (and your rival) all in a row without letting your Pokemon faint, if they do, you must start over again.
You can beat the Pokemon League it is just one of the harder Leagues than in Pokemon Emerald or Diamond.
You need to beat the elite four and then beat the Pokemon league champion
beat the league and he will be gone
