So I'm trying to write a Pokemon fanfic but I've kind of hit a wall.
So one of the protagonists of said story manages to hatch a shiny Beldum and raise it into a Metagross. However, I just learned that Steven apparently had a Shiny Metagross in the anime (I only played RSE and ORAS a long time ago). I really don't want to make it seem like a blatant copy and I don't know what to do.
I really don't want to give up on the whole Shiny thing, and considering both protagonists are from Hoenn, I found it fitting for them to receive one Pseudo from said region each. Does anybody have any recommendations on what I should do?
