Other media

 * In Captain N: The Game Master, the Doc Robot is a small and thin doctor robot with glasses and beard that assists Dr. Wily (A literal "Doc" Robot). He only uses Metal Man's Metal Blades to attack, and was smashed by a giant pipe he cut with a Metal Blade.
 * In the manga Rockman Gigamix, Doc Robot appears in the story Asteroid Blues, which is based on the events of Mega Man 3.
 * In Sega's renowned Sonic the Hedgehog series, Doc Robot is usually the main antagonist.

Trivia

 * His Japanese name, "dokurobotto", is actually the combination of two words -- "dokuro", which means "skull", and "robotto", which means "robot". The name basically translates to "skull robot," though the joke was lost in translation and resulted in the name "Doc Robot".
 * According to an interview with Keiji Inafune, the Doc Robot's design served as an inspiration for Sigma, the main antagonist of the Mega Man X series as it is one of the few characters not designed by Inafune himself. Both antagonists feature a jewel on their head, if anything else.
 * The devices seen attached to Doc Robot at various places are what may be a buster on his right arm, a Quick-Boomerang launcher on his left wrist, and a copy of Bubble Man's Bubble Lead and Crash Man's Crash Bomber module on his back.
