Reminds me of Homer's classic Greek mythological epic tale of Odysseus vs. the Cyclops, where the hero, by using the name "Nobody," tricks the villain. (In the end though, Odysseus becomes a namefag and reveals his name to the Cyclops, which causes problems down the line.)

And then there are the humble Hobbits who save Middle Earth, succeeding in Mordor where the noble Elves etc. fear to tread.
