Quezacotl
Lightning Elemental
Quezacotl looks much like a giant bird when summoned. It uses the element lightning against all opponents and is usually strong enough to wipe out most lesser opponents. His card and card-mod abilities are useful when your party want to upgrade their weapons, as they can provide many useful items. Mid Mag-RF is also very useful early on in the game and can provide you with powerful spells.
Quezacotl can be found early on in the game simply by making Squall use his study desk and look at the tutorial.
