When I fought Darkrai in the last fight and caught it, my game crashed and when I joined again, I was in the Pokemon Center and Darkrai was gone. Was it all in vain what I did in the last 3 days? Would it be possible to give me a Darkrai! I ask you for help!

You can fight the mini-boss Horus to get another chance at fighting him again and being able to capture him, as far as I know. You will need to defeat him without having a single pokemon faint (if I am not mistaken). Good luck!

Greetings, @DangerMV

If you got disconnected while you was catching Darkrai you can get another chance to get it defeating the boss Horon, you can find it above Necropolis.

You will have to defeat this boss without lose any of your pokemons.

 

I hope this have clarified your doubts.

Have a great day,

Nezuko

I doesnt have a pokemon for him :(
