gilgamesh (final fantasy)
Recurring character of the Final Fantasy series, originating from FFV. Enkidu is his sidekick. Role varies greatly from enemy to summon to rival to random NPC. Known to carry various legendary weapons, sometimes taken from various games in the series; in particular, he is on a seemingly endless quest for Excalibur.
Something of an unofficial mascot, Gilgamesh has had more appearances than any other character in the Final Fantasy series, and has been confirmed to be cross-dimensional: The Gilgamesh appearing in each game is the same Gilgamesh, despite the games existing in their own independent settings.
