Doranikov is a robotic cat inspired by Doraemon and originating from Russia. He lives in the cold regions of Siberia, where he serves as a local public servant. A notable documented behavioral characteristic is his tendency to transform into a wolf upon seeing round objects.

He belongs to a seven-robot team called The Doraemons, an old boys' association from the Robot School. Each member has a unique variation of the standard four-dimensional pocket; Doranikov possesses a four-dimensional hat. He shares his teammates' fondness for dorayaki but customizes his with sour cream, reflecting his Siberian background.

The group stays connected using a gadget known as the Friendship Telecard, enabling communication and mutual assistance. Doranikov contributes as a dedicated participant in the team's activities and missions.

Beyond a single film, the character appears with the group in various manga series and animated short films. These adventures often involve confronting antagonists and safeguarding their friendship through collective efforts.
