He takes on Michel Volban de Cabelle, the figurehead of the People's Army, and uses Michel as bait to lure out Cleo. He is the Holy Emperor, and wanted to unite the galaxy in order to be able to obtain the technology of the battleship that transcends space and time. He uses whatever means he can, even marriage to Rachel, the daughter of the Pope (who initially despises him). He also has an innate dislike (later turned obsession) for Cleo, (who he sees as a rival) and a fascination with Michel who was initially his rival before Cleo. He even goes as far as drugging and kissing Michel, who he did not know was a woman, and may have possibly raped her afterwards, as he does not confirm her accusations. After he finds out that she is a woman and not Michel, Vetti loses all interest in her and his attention turns to Cleo. Vetti revealed that he wants to obtain the technology because he has an incurable disease and may die soon. Vetti has Heterochromia - one of his eyes is gold, and one is gray.
