In the series, Tony is the natural son of Karina and Yui (who is not in the movie). In the movie, Tony is the natural son of Jomy and Karina, and in the manga he is the son of Karina and an unnamed father who is only shown in one panel. The first baby not born in a test tube. He is protective of his father and suspicious of Physis, whom he believes Jomy loves more than Karina (in the movie). Tony leads the Mu for a while, although his methods are rather ruthless.
