This was followed by a return to past-style series in the form of Ultraman Max (2005, CBC). In the course of "Max" series, another new hero known as Ultraman Xenon was also introduced. April 2006 saw the 40th anniversary series, Ultraman Mebius, a rookie who will defeat the emperor of all Ultra Monsters, the Empera Seijin which will create a connection between the Ultra Kyodai.
