A Spiky Legend

I present, a yet unnamed legendary pokemon for my fake region, which is back to start with its name. Anyway, here is my dragon sprite, made out of pure boringness. He will form either a pair, or a trio. Anyway, whathever way this goes, here is the dragon/steel legendary for the Riocra region.

If this becomes a legendary duo, this is the Physical Dragon Legendary, and its reverse form is Robchast, the Special Dragon Legendary.
If this becomes a legendary trio, there will be a third dragon, the Mixed Dragon Legendary.

Upper sprite are normal colors, the pair underneath them are shiny.
Info:
Name: none yet.
Type: dragon/steel.
Ability: none yet.
