Agent N is a robot in the service of Dr. Robotnik, as an operative of the Robotnik Intelligence Agency.
Agent N was assigned to oversee the production of Robotnik's Grabber spy-watch robots being produced by Mr. LaTour, though the scheme was eventually uncovered by the Sonic Underground. In the aftermath of this, Agent N succeeded in taking Sonia, Manic, and the LaTours prisoner aboard his gunship. However, Sonic managed to board the vessel, and Agent N was literally taken apart by a swarm of spy-watch robots reprogrammed by Manic.
