For over a decade, Heidi Klum has proven herself Halloween's biggest fan by throwing epic parties and donning over-the-top costumes to match.

As we showed you in our retrospective slide show of Klum's fantastic getups, the supermodel has dressed as a sexy latex-clad Goth, sexy Betty Boop, horse-riding Lady Godiva, sexy pirate, sexy vampire, sexy apple and serpent, sexy cat, scary Hindu goddess, and a fishnets-wearing black crow.

Now, drumroll, her 2010 costume is... a sexy robotic superhero! (Created by Martin Izquierdo, of Victoria's Secret wings fame.)

In this sneak peek at Klum's high-tech costume, we get a glimpse at the red-and-purple contraption, which appears to be on stilts and has some nifty iron-clad armor in the boob area.

Klum will debut this amazing work of wearable (though, we're not sure walkable) art at her Halloween party on Oct. 31 at New York City's Lavo nightclub, where we're told the drink of choice will be, naturally, Bloody Absolut Fast Marys.
