Habunake

Habunake is a serpentine Pokémon that is usually depicted scrunched up like an accordion. It is mostly black in color but has several markings on its body. It has yellow hexagon markings that run from its head to its tail, small yellow bumps where it touches the ground, and various purple scar-like marks. It has elongated red fangs that protrude from its upper jaw and fierce red eyes. Its tail is partially red and has a blade-like shape. Habunake sharpens its tail on rocks and can use it for its former signature move, Poison Tail.

Habunake wraps around its opponents to make them unable to move. Its tail and fangs are venomous and are used for striking and poisoning prey or enemies. It has been bitter enemies with Zangoose for many generations. It lives in grasslands and savannas.
