The Atomic Punk
Octi-Prime is a radical departure from your other designs. I like your other heroes but this is unexpected. Almost out of his element, not to be confused with a villain.
The design flows. I don’t see him carrying a planet; a blue moon in the background. The spiked gloves add to his menace. The purple and red background against the otherwise green body. With the glaring crown on his head. Very interesting. My curiosity is piqued.
