To catch a shiny Gastly, there are three things you can try. First off, you can try catching a shiny Gastly in the wild. However, there is a 1 in 8192 chance of encountering a shiny Gastly and may take you hours to find one. Second, you can try breeding a shiny Gastly. There is a greater chance to find a shiny Gastly by breeding, but it still takes a few hours depending on how well you breed. Last, you can use your PokeRadar to chain Gastly. Depending on your luck and how well you chain, you can find a shiny Gastly within minutes or more. If your chain of Gastly reach up to 40 or more, your chance of finding a shiny patch is 1 in 200. A shiny patch will contain a shiny Gastly. You may even find several shiny Gastly from chaining. If you're really lucky, you can get a shiny Gastly from your first or second or even tenth chain.

You can find them in the Lost tower(South of Solacean town)and In the Old Chateau (In Eterna forest). They are mostly found at night. A Shiny gastly has a blue aura surrounding it. Gastly will evolve at lvl 25 into Haunter. and to obtain Gengar, you must trade. (btw, it is a ghost type meaning that it is useless against normal types.) Good luck trainers!
at night in sprout tower or in route east of Violet city.
