Secret Agent N

Secret Agent N is a character from The Super Mario Bros. Super Show! episode "On Her Majesty's Sewer Service / 9001: A Mario Odyssey".

A wise man with a British accent, Agent N runs Super Spy Headquarters, a base located beneath Spy Land. When his top agent James Blonde was turned to stone by Koopfinger, Agent N asked Princess Toadstool to recruit Mario and Luigi into stopping Koopfinger.

Upon meeting the Mario Bros., Agent N presented Mario and Luigi with their Spymobile, along with various plumber-related spy tools, like a laser drill and an atomic screwdriver. Afterwards, he sent the plumbers on their mission to Fort Hard Knox to stop Koopfinger.

Agent N didn't appear again until Mario and Luigi had succeeded in defeating Koopfinger, to which he congratulated them. He was then unable to stop Mario from testing his new spaghetti bomb, but Mario didn't mind, for he claimed to like spicy food.
