The young leader of the Yunos Knights, a squadron of robot fighter pilots. Uptight but very responsible, he is extremely loyal to Dhianeila. He initially dislikes Age and gets jealous over Dhianeila becoming close to him, but quickly becomes Age's friend. Iolaus has a secret collection of holographic pictures of Dhianeila.
Iolaous has the ability to teleport himself and another, when he touches them. The range of this ability has so far been shown to be intra-planetary, with his longest teleport so far being from orbit around Titarros to the surface of said planet. Iolaous can only teleport others along with him if they are mentally willing to do so. His mecha can teleport when a special engine is engaged, and the engine is also capable of transporting other mechas along with his own, if distance between Iolaous' and the other mechas allows.
His character represents the Theban hero, Iolaous, friend to Heracles.
