Ultraman Tiga
"Ultraman Gaia" takes place in yet another universe, one that is different from the world of the Shōwa era Ultramen ("Ultraman" to "Ultraman 80"), as well as the world of "Ultraman Tiga" and "Ultraman Dyna". In a departure from most of the other series, there are two Ultramen as the main characters. They have conflicting philosophies in regards to defending Earth from a mysterious, malevolent and extremely intelligent cosmic entity.
