A Ferengi, Rom's son and Quark's nephew; grandson of Ishka; who at first did various odd jobs around his uncle's bar. Nog had a far from spotless record; in fact, in "Emissary", he was caught fleeing after looting the assay office, and was used by Sisko to blackmail Quark into staying on the station. Not long after that (in "A Man Alone"), Nog and Jake met, and became inseparable, much to Sisko's chagrin.
During the first two seasons, Nog and Jake were quite the terrible twosome. Among other things, they were partners in a business venture that ended up with 5 bars of latinum ("Progress"); and they tried to pilot a runabout together after Sisko and Quark were captured by the Jem'Hadar ("The Jem'Hadar").
Then, in 2371 ("Heart of Stone"), after undergoing his Attainment Ceremony, Nog suddenly declared that he wanted to become a Starfleet officer, offering Sisko latinum to become his apprentice. Sisko finally agreed to write him a letter of recommendation to the Academy, after Nog proved he could work hard, and after the young Ferengi admitted his real reason for wanting to join Starfleet: he didn't want to repeat his father's mistake of going into business without having the lobes for it. Finally, in "Little Green Men", Nog was taken to the Academy by his father and uncle, though they took an inadvertent side trip through a time warp to 1947 Earth.
For a year, Nog attended the Academy, and was seen only in "Homefront"/"Paradise Lost". Then, in "The Ascent", he returned to DS9 for a year of field study (though he never did go back to the Academy), and he and Jake became roommates. Nog's first bridge position on the Defiant was relaying orders from the bridge to engineering in "For the Uniform". He was one of the Starfleet officers who evacuated the station in "Call to Arms", but not before he attended his father's wedding to Leeta.
Nog, who had been field-promoted to Ensign, returned to the station again (in "Sacrifice of Angels"), and later that year was one of the Ferengi team that Quark put together to rescue Ishka ("The Magnificent Ferengi"). In "Valiant", he was also sent with Jake to Ferenginar with a diplomatic message for the Grand Nagus; but they were attacked by a Jem'Hadar ship, and rescued by the Valiant. Nog was caught up in it all when Watters made him chief engineer and a Lt. Commander; however, after all the other officers were killed, he chose to escape with Jake and Chief Collins.
In "The Siege of AR-558", Nog was doing recon when he was shot by the Jem'Hadar, and had to have the lower half of his left leg amputated. After returning to DS9 with his new biosynthetic leg, Nog took refuge in a holosuite, in the Vic Fontaine program ("It's Only a Paper Moon"). Finally, though, after a confrontation with Vic in which he confessed his fears, he was able to face reality again. He returned the favor to Vic by helping pull off a holographic casino robbery ("Badda-Bing, Badda-Bang").
After Nog proudly watched his father become Grand Nagus ("The Dogs of War"), he helmed the new Defiant in the final battle against the Dominion, and was made a lieutenant. Putting Nog in for the promotion had been one of Sisko's last official acts ("What You Leave Behind").
Other facts: Nog's year of birth was never stated, but he was older than Jake. He did not know how to read until Jake taught him in "The Nagus". Nog was seen as a Starfleet captain in an alternate future in "The Visitor".
