[Rvnl]

Hi, im creating the GEN III on PkHex and i notice that all shiny pokemons have different SID, its that ok? and normal Pokemon have all the same SID.

No Shiny:

That isn't how they normally generate in-game, no. All Pokémon caught or hatched by you should have your exact Trainer Name and IDs. The reason the SID is different is likely a result of you holding down the ALT key when clicking the Shiny button, which alters the Trainer or Secret ID instead of the PID to turn it Shiny. 

This means they're legal shiny Pokémon, but not legitimate, and they won't behave as if you caught them on that savefile. See the guide for PID mismatch if you want to change the PID instead.
