Doc Robot
Doc Robot is interesting for several reasons. First, Mega Man must face him eight times across four special stages. In each battle, Doc Robot channels the power of a Robot Master from Mega Man 2, essentially making these encounters rematches from Mega Man’s previous mission and bringing the grand total of Robot Masters faced in Mega Man 3 to 16.
Additionally, Doc Robot’s Japanese name (“Dokurobotto”) translates to “skull robot,” matching his appearance as well as that of Dr. Wily’s skull-themed castles. This was lost in the Western localization, however, and “Dokurobotto” was interpreted phonetically as “Doc Robot.” Because of this and despite his menacing in-game design, Doc Robot appears as a small, elderly robotic doctor in the Captain N: The Game Master cartoon.
Mega Man 3 was the first game to have Mega Man run to the middle of the room and teleport upward after defeating each Robot Master.

Several cheats were left in the original NES version. Holding right on the d-pad of the second controller enables Mega Man to jump much higher than normal. This also allows players to jump in and out of bottomless pits and can be used to enable invincibility. Holding up on the second controller makes the game run in slow motion, while holding up and A freezes everything on screen, including Mega Man.
