Odin

Non - Elemental
Odin is the Norse horseman back from FFVII to help your party in times of need. He attacks with Zantetsuken. An attack that splits the enemy in half, instantly ending in a victory for your team. He dosn't appear in boss battles excluding Seifer on Lunatic Pandora.
Odin can be gained by travelling to the ruins on the Centra Continent. You will notice their is a timer of twenty minutes to find him. After this timeer runs out you will die. To find him you must travel up the tower using lifts and ladders, creating invisible platforms. Eventually you will reach a dead end. Here you must pull the eye from a statue and place it into the socket of a statue on the roof. This will give you a code. Input this code by placing both eyes into the lower statue and a door will open. Odin is in here. Just defeat him and he will join you.
