The C.D. ROM Ram is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a gigantic quadruped robot, modeled on a male sheep, otherwise known as a ram. It is extremely powerful, and can charge enemies at great speed. It is programmed by means of a CD slot on its hind leg.
The C.D. ROM Ram was activated by Crocbot to defeat the Downunda Freedom Fighters, who were a threat to his plan to take over Downunda and overthrow Robotnik. Although the Ram kept the Freedom Fighters busy for a while, even butting Barby Koala so hard that she was sent flying all the way to the Great Crater, it was destroyed by one of Walt Wallabee's Bomberangs.
