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.
- Sleet says in the episode, "Those RIA metalheads are always trying to hog the glory", implying Agent N is not the only operative of the agency.
- Agent N references Robotnik's catchphrase from the earlier Adventures of Sonic the Hedgehog cartoon by saying Robotnik "hates hedgehogs" in a similar tone.
