In the Comics, the Annihilators appear to be tall humanoids that resemble the Meridianites (namely Cedric and Daltar). They wear Green Hoods and light-greenish-brown robs. They have the symbol of the Meridian royal family or the Seal of Phobos on their hoods and belts. In the animated series, they appear more Golem-like, with greyish-black granite-like skin. Their clothes are also completely greyish-black and their faces are not visible.
