ウルトラマンティガ
Starting from the 1998 trilogy, Dan had grew his hair and changed his outfit under Kohji Moritsugu's demand to be based on his favorite actor, Steven Seagal. According to director Shinichi Kamisawa, the central theme of "Ultraseven" was "protecting the Earth from extraterrestrial invaders", while the 1998 trilogy was "the coexistence of Earth and mankind". From here onwards, the collaboration with VAP for original video contents was due to their past association with Tsuburaya Productions during the making of "Moon Spiral" miniseries. With the exception of Kōji Nanjo, actors for the new members of Ultra Guard were carefully selected through an audition of 2,000 candidates. Shigeki Kagemaru was not able to reprise his role as Kaji due to the filming of "Ultraman Tiga" had already wrapped up by the time the trilogy's filming took place.
