I mean, we sometimes get shiny legendaries, so I was thinkingmaybe there is a 1 in 8192 chance that the shiny Gyarados can be a normal Gyarados. Probably not, but just thinking.
No, Its Always Shiny. As Team Rockets radio Waves Did That To it, unless the waves didnt work(which in that case, the whole plot would be ruined) whcih would be stupid.
Now Ive Got Movesets to do, don't i?
No, shiny garydos is shiny. the girl in front of the lake says: "Maybe he is red with rage." after the 12 times I played that game, I got him every time.
I think it must be programmed into the game or something that he can ONLY be shiny, that he doesn't have even the slightest chance of not being.
