The Metarex Carrer was an angular Metarex with a single dark blue eye and a matching orb on the chest.
The Metarex Carrer was dispatched by Dark Oak to retrieve the Planet Egg of Sonic's planet, and succeeded in doing so despite the efforts of Sonic, Knuckles the Echidna, and several of their allies. Later he was deployed to guard Metarex Kingape's departure with another Planet Egg from a jungle-covered planet, only to run into Sonic's allies aboard the Blue Typhoon. This time the heroes proved triumphant, with Carrer meeting his end on the receiving end of a blast from the Sonic Power Cannon.
Powers and abilities
The Metarex Carrer was immensely powerful as even the united efforts of Sonic and Knuckles the Echidna could not defeat it. It was equipped with claws, tentacles and various electrical energy weapons.
