Ion bonder
The ion bonder was an energy weapon owned by Nyssa of Traken, allegedly based on ion energy. It shot a green ray.
Stunning was its main effect, even if its ion rate could be stepped up. It was used by the Fourth Doctor as well. (TV: The Keeper of Traken [+]Loading...["The Keeper of Traken (TV story)"])
