My creation for the "9" contest - Luxo the Destroyer, named lovingly for the Pixar mascot.
Luxo is a deceptive hunter/killer, allowing his less than threatening appearance to lull targets into a false sense of security. What escapes the reach of his umbrella-remnant claw is retrievable by the razor-headed harpoon mounted on his shoulder. He travels via the rolling ball under his lamp base, which makes an ample crushing mechanism when the occasion calls for it.
