A friend traded me a shiny Kyurem and I have a normal Reshiram so if I fuse them, will the result be shiny? I can't find the answer myself because I haven't encountered Kyurem in ORAS to get the DNA splicers.
Everything remains from Kyurem: IV's, EV's, Nature, Shiny or not, Nickname, Pokeball caught with, the only thing it get's from the other dragon is the signature move.
