Save it before you catch dialga then every time he is not shiny restart it until he is shiny.
With luck and with the right game you can get rare colored or shiny dialga

No, the shiny DIALGA dos'nt give any added stats even if it is shiny or not however if you want to have a green DIALGA with a shine when it enters battles, why not?
You don't know?!It's Dialga of course!
Yes, however the odds that the Pokemon you pick is shiny are 1 in 8912 and there is no way to reduce that without cheating.
