* BadassBoast: After Gilgamesh and Enkidu destroy the Bull of Heaven - the divine beast sent to destroy them for mocking the goddess Ishtar - Enkidu shakes the bull's torn off haunches at Ishtar, threatening to do the same to her if he catches her.
* DesignatedHero: Gilgamesh is a tyrant whose outrages against his people drive them to pray to the gods for aid. Later, he and Enkidu kill Humbaba solely to win glory, then anger the gods with their arrogant actions. By 21st century standards, Gilgamesh is ''not'' very heroic.
* EscapistCharacter: A king, partly divine, all but invincible, SuperStrength, gets laid with every girl in his kingdom but snubs the goddess of sex... Gilgamesh is wish-fulfillment SnarkBait by modern standards. He's effectively protected by a GrandfatherClause, since he predates most tropes.
** This may be an UnbuiltTrope since Gilgamesh is a tyrant which no one is liking, killing the monster causes his best friend Enkidu to die, and Gilgamesh's heroic quest fails.
* LGBTFanbase: Fans love the HoYay.
* MemeticBadass: The sole reason why the story survives today. We wouldn't have so many tablets if they weren't being made and put all over Mesopotamia just to tell everyone how badass he was and how you can never hope to reach the level of sheer badassery he was at.
** FridgeBrilliance can be applied here when you figure that well, though he may have failed to achieve ''literal'' immortality within his own story; the Epic of Gilgamesh in the meta sense ''has'' become immortal and survives to this day.
* MemeticMutation: A Japanese metal band named themselves after this story, which then resulted in [[http://i0.kym-cdn.com/photos/images/original/000/210/414/Girugamesh01.png one of their fans being immortalized on the internet]].
* {{Narm}}: "Enkidu you son of a fish" silliest line from a truly historic story ever!
** NarmCharm: Who ''doesn't'' want to use that line on someone now?
* NightmareFuel:
** Perhaps the most memorable moment in the story -- what finally leads Gilgamesh to accept that Enkidu is dead -- is when he sees a worm ''crawling out of his nose''.
** Gilgamesh decapitates the Bull of Heaven and throws one of its body parts at Ishtar.
* SignatureScene: Enkidu's death.
* TearJerker: The death of Enkidu. Doubles as {{Mangst}}.
* TranslationWithAnAgenda: The Stephen Mitchell translation could be seen as {{Bowdlerization}} that HideYourGays from the original, changing the literal, "they kissed each other and formed a friendship," to "they embraced and kissed. They held hands like brothers."
* ValuesDissonance:
** Despite all of his previous outrages, Gilgamesh is accepted back as king of Uruk at the end of the epic, with neither humans nor gods nursing resentment against him. Many 21st century readers would find this unbelievable.
** The tendency to paint Shamhat as a harlot and seductress. In the story, her sexual encounter with Enkidu humanizes him. Her week-long tryst with Enkidu isn't a fall, but the first event that ''raises'' him above the level of an animal.
** Despite Ishtar's less-than-flattering portrayal in this story, she was a very important and revered goddess and sex is part of the sacred duties of her priestesses.
* WhatAnIdiot: If you have a plant that will make you immortal, ''don't'' wait until after you've taken a bath to use it.
** He was actually going to give it to an old man to see if it would turn him young again, so he was probably playing it safe since he didn't know if it would actually kill him instead.
* {{Woolseyism}}: Since some portions of the story have been lost, some translations feature original material to fill the gaps which occasionally works quite well. Most notably, at least one changes Gilgamesh's motivation from wanting immortality for himself to wanting to bring Enkidu back to life.
