Shiny Hunter...again
I think Game Freak must do their work well,and tell us if can exist more than 1 Arceus,Giratina,Dialga or Palkia. etc.
I saw a shiny Entei once. It ran off and is still running around so I don't know if he is still shiny.
i think he won't be shiny anymore. you'll just have to flee and encounter again and again to get him shiny. :\
