Question

Is there a way to get a Crobat with Nasty Plot and Infiltrator?

Answer 1

You're gonna have to start with a Zubat with Infiltrator. Make sure it's female, or breed it with a Ditto until you get a female Zubat with Infiltrator. Breed it with a male Honchkrow that knows Nasty Plot, then you've got a chance of getting a Zubat with both Infiltrator and Nasty Plot.

Answer 2

Well here is how you do this if this is oras then all you need to do is keep doing that dexnav thingy until you see it have that infiltrator. If your lucky you might get one with nasty plot but if you aren't here is how you breed it you get a Male honchkrow that knows that plot of the nasty breed it with the female inflitrator zubat and you get a zubat with inner focus or inflitrator
