It is Dark Dialga of the appearance and my Dialga than the most new work of Pokemon Mysterious Dungeon.
(My Dialga treats you like a female as there is it judging from far in advance.)
I who cannot help loving Dialga can see Dark Dialga.
Since "Dark" and the name arrive, Dark Dialga is wicked and it seems to be harmful to genuine Dialga.
It is put a logo of Wii on it and a T-shirt wearing of Dialga in secret.
