I was very happy to find my first shiny which was a porygon and I bred it. I wish to do the same thing with staryu. The last time, I just bred a box full of porygon searching for modest. Is there any other method.( In fire red)
Unfortunately, the only way to search for Shinies in FireRed is to keep spamming random encounters, soft resetting certain Pokémon, or breeding (which all have the same odds). The Masuda Method and Poké Radar were added in Gen IV, the Shiny Charm in BW2, and chain fishing in Gen VI. Unfortunately, you are stuck with the odds of 1/8192. But don't give up if you really want that Staryu!
