no but its spelt gyarados lol
there are two ways of getting a gyrados in Pokemon diamond: 1. you can use a super rod. 2.you can also use your old rod to catch a magikarp and then train it to level 20 or i think 22 so that it can evolve to a gyrados.
1) catch a magicarp with an old rod 2) evolve it. or catch 130 "gyrados" with a super rod at various locations.
