Few things say "instant Godlike" in the RPGDL like being a Spiran Summoner, and Maester Seymour Guado is certainly no exception. He was strong enough to complete a pilgrimmage and earn his Final Aeon, Anima, although he never did use it to fight Sin. Even death couldn't slow him down; as an Unsent, he gained the power to manipulate the pyreflies of his own body, instead of his Aeons, and the result was one of Final Fantasy X's most feared bosses.

In its most advanced stage, Omnis, Seymour's gel-like body is almost impervious to physical damage, and he can cast four -aga spells a turn. This combination makes him a brutal Godlike, one who sports a winning record despite having faced three powerful Godlike champions.
