Stacks'n! [sees pronunciation] OH, okay. I'm wondering if the name's resemblance to "Satan" is coincidental or intentional, considering this guy definitely looks like he's got a demonic theme going.
Anyway, this design is really frickin' cool, and coherently goes together with Cobaltus's normal appearance. Now that I know that the rusty stuff on Cobaltus is an infection, I really like the rusty appearance for it. I also like how the infection/evil lightning is colored more sinisterly than the lightning for Cobaltus's normal powers, and how the eyes resemble the lightning. Really cool. Great execution as always, and congrats on the front page!
