Here you go!
Regidraco, Use any pallete. I decided, though. I want the gray body to be blue, please. Salamence would be best.
Regidark, I want you to use Sabelye's pallete, making the body deep purple instead of gray, but the cloak should remain black.
Regipsy, ironic I almost forgot my favorite type. Just sprite it as it's shown. The body should be "Shiny" considering it's made of metal.
That will be all.
