Seymour transforms into Seymour Natus with a mechanical, hovering creature called Mortibody to assist him. Tidus, Yuna, and Auron can speak to Seymour at the start of the battle with Trigger Commands to raise their Strength or Magic Defense. The Mortibody starts a round by casting a basic elemental spell on the party. Seymour will follow with a Doublecast of that spell's Level 2. Mortibody will regularly use Desperado, which removes all positive statuses.
