Rocco: Vulture guy, The Red Amazon's right hand. I don't have much sketches or concepts about him, though. (Curse you, deadline!)

The Red Amazon and Faris.
Faris, from the rival gang the "Magnolia Vandals" is a nechromancer with smokey hair. He pulls out corpses from there.

Gabriel: A silver-tongued demon. He's a lone wolf (antihero) who sides with whoever gains his approval, or offers him a reward.

The Red Amazon: Leader of the Hero's biker gang. She is a vampire, and usually wears full-body armour to protect her from the Sun in daytime

Leapfrog: Leader of the rival gang: "The Magnolia Vandals". She is very vain, has great taste in clothes and drinks. She's also kind of a douche. I was exploring the ideas of toad+frog+spider area.

KING: The "mascot" of the main biker gang. It ss always seen with Klaus, and never leaves his side. It only speaks to Klaus.

Klau's design variations

Klaus: Main character of the story. The Gang's main fighter/muscle. He's a very though, silent guy with a heart of gold. After a bike accident, his main arms were ripped off. He can not drive his bike, KING is more than happy to sit on his lap and drive for him.
