The Yawner is an Apache Indian who appears in the tale Small Medium, Large Headache. Technically dead, he and his compatriot Mangas Colorados are resurrected by the witch-doctor Misquamacus and given a borrowed body in an attempt to regain control among the Apache Indians and throw the pesky paleface, and brownface, and blackface, out of Howondaland. He is not a nice person to know and tends to shout things like "Geronimo!", with enthusiasm, if given a chance to display his creative whittling talent with sharp knives.
