More soon, this is a very old (and beloved) character but for some reason I don't draw him much.
Dar is a chaos-induced "copy" of Rad, but he's obviously not an exact duplicate.
Main differences between them, apart from colors:
-- Dar has more markings on his skin, and they extend further down his limbs and torso
-- Dar is slightly curvier with slightly softer features, and hair is naturally flatter, while Rad's naturally tends to curl
-- Dar has one extra piercing on his right ear, on the helix, giving him a total of five ear piercings
