Organic battery

An organic battery is a key component of Robotnik's early badnik designs in Sonic the Comic.

In this continuity, badniks are not roboticized animals (unlike other continuities, such as the Archie Comics series). Rather, they are autonomous robots that can install animals as "organic batteries" or power sources. The presence of an organic battery also acts as a defense mechanism: Sonic is forced to hold back the strength of his Spin Attacks for fear of harming the captive within.

Some more advanced badniks, in particular Trooper badniks and the Metallix series, do not possess organic batteries.
