I was playing White 2 on my 3DS and I encountered Virizion and I accidentally defeated it with my Cobalion. Will it come back and if it does, how can I find it again?
After you defeat the Elite 4 and enter the Hall of fame you get another chance to catch Virizion/Terrakion/Cobalion.
They appear in the same location at level 65 instead of level 45.
Hope I helped.
Yes it will. All you have to do is go defeat the elite 4 and it will be back. Hope I helped!
After you complete the game, (a.k.a Defeat the Elite Four) you can go back to the same spot where you defeated Virizion and try again. If you don't catch it, you have to repeat the process until you do. Hope I helped.
