The galvaniser was a torture device used by Anzor, appearing as a short blue rod with a glowing orange tip. Anzor used the galvaniser on his classmates to ensure that they did as he said. He particularly bullied the Doctor, forcing him to do his navigational homework as he was too stupid to do it himself. He used the galvaniser on the Doctor at least once, as he later threatened to "revive your memory of my galvaniser" to terrify him.
Only one person ever stood up to Anzor, a boy named Cheevah. Anzor sealed Cheevah in a block of crystal and dropped him from the academy bell tower into the school yard as a punishment. The Doctor later told Peri that Anzor had forced the rest of the children to laugh at this under threat of a shock from his galvaniser. (AUDIO: Mission to Magnus)
