Egil is a Machina, Vanea's brother, and Miqol's son.
He is the leader of the Mechon army, creator of the Faced Mechon, and the mastermind behind their invasion of Bionis. Egil is described as kind, brave, and helpful towards the poor by his own people. He was friends with the giant Arglas, with whom he discussed the idea of leaving the world of Bionis and Mechonis in search of new worlds. Yaldabaoth is the name of his faced-mechon.
After Meyneth's death, Egil bids farewell to Vanea and encourages everyone's escape from Mechonis. As they escape from Zanza aboard Junks, Egil uses Mechonis as a shield so they can escape. Egil is killed as his Mechon blows up.
