* LGBTFanbase: Fans love the HoYay.
* MartyStu: A king, partly divine, all but invincible, SuperStrength, gets laid with every girl in his kingdom but snubs ''the goddess of [=R3D H0T S3XX0RS=]''... Gilgamesh is wish-fulfillment SnarkBait by modern standards. He's effectively protected by a GrandfatherClause, since he predates most tropes.
** UnbuiltTrope: A lot of the wish-fulfillment elements are portrayed as immature character flaws that needs to be overcome (consider how later ClassicalMythology might have treated the same subjects), his heroic adventures only sets of a chain of events leading to the death of his best friend and when going on the most important quest of his life what do he do? He fails.
* 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://images.encyclopediadramatica.com/images/a/ab/Girugameshguy.jpg 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?
* TearJerker: The death of Enkidu. Doubles as {{Mangst}}.
* ValuesDissonance: The tendency to paint Shamhat as a harlot and seductress. Despite Ishtar's less-than-flattering portrayal in this story, she was a very important and revered goddess and the sex is part of the sacred duties of her priestesses. Not to mention that the weeklong tryst with Enkidu isn't a fall, but the first event that ''raises'' him above the level of an animal.
* 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.
*** So basically, not only was Gilgamesh not an idiot, he was actually incredibly GenreSavvy! Impressive, considering the age of the tale.
*** The real problem wasn't whether Gilgamesh was GenreSavvy enough, it was that he was WrongGenreSavvy. Which might be understandable since he was the first to try to subvert many foolish actions, but because he was the first, he didn't realize option 2 could have just as many problem as option 1. For example, he knew it was bad luck to fall for Ishtar, but he didn't seem to realize just brushing her off and rebuking her was just as bad as accepting her advances.
* {{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.
