Astro Zombieg

Astro Zombieg (アストロゾンビーグ) 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. Pharaoh Man summons them in Mega Man 2: The Power Fighters.

Trivia

 * Astro Zombieg is a reference to the zombie enemies from the Ghosts 'n Goblins games.
 * The name Astro Zombieg may also be a joking reference to B-Movie legend Ted. V. Mikels who directed the 1968 movie The Astro-Zombies and its 2002 sequel/reinterpritation Mark of the Astro-Zombies.
