Battery Biscuit

Battery Biscuit is a device used to feed Rush in the Mega Man animated series. They resembled dog biscuits, only with the positive and negative signs on each end similar to a battery.

They are primarily used as a means of coercion for Rush if he is reluctant to carry out a command, similar to the character Scooby-Doo from the franchise of the same name.

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