Tony Husbando

The very first natural birth since the implementation of the SD system, Tony was born to Mu parents on Nazca. He marks the first of several similarly born Mu children who experience rapid growth and possess Type-Blue powers far superior to many of the other Mu. Despite being hot-headed and rebellious, he holds a deep affection for Jomy, calling him "Grandpa" (despite having no relation to him; however, in the movie version, Tony is depicted as Jomy's son). In the manga, his mother explained to him that Jomy was the "father" of all married couples (in that he allowed the marriages), hence the "Grandpa" nickname.
