The principal personal weapons of the Mandarin are the 10 rings which he wears on the fingers of both hands. The rings' operations cannot be explained by contemporary Earth science, but it is known that they served as near-limitless power sources for the warp-drive engines of the Makluan starship of Axonn-Karr. The Mandarin learned how to convert the rings to his personal uses and to make them respond to his mental commands. The fingers on which he wears each ring, and the known functions for which he uses each ring, are given below.
