Monster-brother was the term given by Cody Sunn-Childe to the psychic external manifestations of his violent passions.
He let them roam free in the jungles of the Kingdom of Dreams so that he could maintain inner peace. When some of the beasts were provoked into violence by Chewbacca and Lando Calrissian, Sunn-Childe was forced to reabsorb them into himself.
Later, Captain Plikk's attack caused Cody to lose his temper, releasing the monster-brothers as giant demons which attacked the Imperial fleet.
