Caw

Caw was a big, golden bird who could speak and worked with Baltazar. Caw was living metal from Pheros and ate gold, and Baltazar promised him all the gold he could eat. Caw had a son called Squawk. Caw had turned on Baltazar and sent him to the prison planet Volag-Noc, but Caw worked with him again after tricking The Tenth Doctor and Martha Jones to find the Infinite for them. Caw's fate was sealed when he was shot by Gurney. (DW: The Infinite Quest)
