The titan is a monster in NetHack. It is infamous for its guaranteed appearance on one of four variants of Medusa's Island and can be difficult for a player at that stage of the game to defeat due to its tendency to summon large swarms of monsters. Titans are therefore one of two significant obstacles on the average dig for victory (the other being minotaurs).
The greatest threat titans pose is the ability to summon monster swarms, so be prepared for any nasty to spawn. Note that titans cannot be genocided, so don't even try it if you're in trouble. Titans do respect Elbereth, which can be a lifesaver. It will not, however, stop them from continuing to summon nasties, including the Elbereth-ignoring minotaurs, elf-lords, elvenkings, captains, and couatls. One can also try taming them, although getting a charm monster spell past their high magic resistance can be difficult.
Yet another option is to put them to sleep. A wand will sometimes miss due to their low armor class, but is usually worth trying several times. Titans' magic resistance will make spells of sleep difficult. Potions are a good choice.
Cockatrice corpses are an excellent way to rid yourself of a titan, provided you have gloves. A titan may even summon a cockatrice for you!
The combination of spell-casting, a decent melee attack, and excellent speed, as well as low AC and high magic resistance makes titans superb fighters, especially if you equip them with a powerful weapon and strong armor. Titans are obtainable from polymorph traps, and contest balrogs as the best monster obtainable by such means. One drawback is that they do eat, though you will be grateful of this the next time you fall down a shaft and find all your pet titans remain tame. But be prepared to handle a titan confused from hunger!
Titans can be genocided in SLASH'EM.
Gaea, mother earth, arose from the Chaos and gave birth to
Uranus, heaven, who became her consort. Uranus hated all
their children, because he feared they might challenge his
own authority. Those children, the Titans, the Gigantes,
and the Cyclops, were banished to the nether world. Their
enraged mother eventually released the youngest titan,
Chronos (time), and encouraged him to castrate his father and
rule in his place. Later, he too was challenged by his own
son, Zeus, and he and his fellow titans were ousted from
