Battery Biscuit

Battery Biscuits were a device used to feed Rush. They resembled dog biscuits, only with the positive and negative signs on each end similar to a battery.

They primarily appeared in the Ruby-Spears Mega Man TV show as a means of coersion for Rush if he is reluctant to carry out a command, similar to the character Scooby Doo from the franchise of the same name.

A battery biscuit also briefly appeared in Issue 19 of the Mega Man comic serial by Archie Comics.
