Quetzalcoatl

Quezacotl, also known as Quetzalcoatl, is a recurring summon in the Final Fantasy series. It's appearance has changed greatly since it's first appearance in the relatively late Final Fantasy VIII. But it always appears as a Lightning-based Summon, and as a winged creature of some sort.

Final Fantasy VIII
Thunder Storm emwoRkhQNmo Quezacotl is one of the first two Guardian Forces available in Final Fantasy VIII. It is obtained by entering the tutorials from Squall's desk in the classroom at the very beginning of the game. If Squall does not access the tutorial before leaving Balamb Garden for the first time, Quistis will give both Quezacotl and Shiva to Squall before reaching the world map.

Its Japanese name is ケツァクウァトル (Ketsakuwatoru); in the French version, it is known as Golgotha.

Quezacotl's attack, Thunder Storm, is an elemental lightning attack that damages all enemies.

Etymology
Quezalcotl is named after Quetzalcoatl, one of the major deities in ancient Mesoamerican mythology. Quetzalcoatl was typically represented as a "feathered serpent", which is also where his name derives from in Nahuatl. Due to the many civilizations worshiping Quetzalcoatl (Maya, Aztec, Toltec, etc.) in the span of almost 2,000 years, the exact attributes and significance of this god varies. Though, most stories agree upon Quetzalcoatl being the god of the morning star and being known as the inventor of books, the calender and the giver of maize to mankind. The worship of Quetzalcoatl was, in some religions, connected with human sacrifices, while in others, opposed to human sacrifices - in Final Fantasy, the creature doesn't bear much resemblance to its source and is a replacement for other lightning-based summons, like Ramuh.
