Darko is the son of a wealthy Mafia head in Magix, seen in the comic series. He has romantically pursued both Icy and Bloom, though his only legitimate affections are for Icy.

Darko has vibrant blue hair styled in the "emo" fashion, with his bangs angled sharply towards one eye. He wears a ruffled white shirt under a dark blue leather jacket, both of which are tucked into fitted blue jeans. He also wears black leather boots, a turquoise ring on his index finger, a brown belt with a brass collar, and a dark blue gem affixed to his neck by a thin string. He also sports a mole under his right eye and he has a scar on the left side of his face.
