As we mentioned a few days ago, today it is already possible to capture Pokémon Ditto GO, though, come not appear how a Pokémon anyone.
Specifically, Ditto appears transformed into another Pokémon, so to make us deal with it we will have to try luck with other Pokémon until we finally find him.
For the moment, and from what I've been reading, Ditto appears transformed into Pidgey, Rattata, Magikarp or Zubat, so as I said, all you have to do is try luck by capturing those Pokémon.
Moreover, I remind you that today has begun a new event which will get double experience and stellar dust than usual, so do not hesitate to go out and use it .
Pokémon GO is available free and universal.
