Omg I can't believe I finished this in one day.
I was looking through my gallery and I noticed that I didn't have any pics of Rai not in human form o-o So here you go. Shadow Dragon Rairai is basically Raiden without any magic to make him look human. Stands around 50ft~ or so and is capable of both shadow and lightning attacks.
I like his claws too. They are kind of a toss up between Kurai's fins and Eve's true claws. If Rai spreads out his fingers you can see the webbing between each one so those make him a good fighter and swimmer. Each talon isn't a true talon either. It's actually the first finger bone grown way out past the skin and into a point, so just like bones, they break, but they're flexible and take hits easily. Unlike true bone though, they're nearly solid inside so that makes them a bit heavy to throw around.
Since he's a shadow dragon, I thought it fitting to throw a shadow aura in there. x3 I love how this came out and I like the background for it. I'll probably do backgrounds from now on since it took me maybe 5 min to make it.
