Astro Zombieg

Zombex is the frightening zombie robot in Mega Man 7, and is (appropriately enough) only in Shade Man's stage. They emerge from coffins; in the first part of the stage (as a nod to the zombie horror movies) these coffins rise from the ground to unleash them. When shot, some of their parts fall off (sometimes an arm or even the head!). They need to be dismantled completely to be destroyed.
