- Set in two years after Tiga's final battle, Daigo was approached by a mysterious woman, Kamila, who possessed a dark version of the Spark Lens. It is then revealed that more than 30,000,000 years ago, Tiga was originally evil in nature, part of a group of four that dominated Earth. The group consisted of Dark Tiga, the woman in gold(Kamila) with telepathic abilities, an evil Ultraman in red with superhuman strength and another in purple with superhuman speed. One day, Tiga fell in love with a local human, and decided to convert from darkness to protect her from harm. Being the weakest of the four, Tiga quickly became a target of the group. However, unbeknownst to the group, the original "talentless" Dark Tiga possessed the ability to absorb powers from fallen enemies. As he eliminated each of the three dark members and sealed them away, he absorbed their powers which explains new Tiga's color patterns (purple, red and gold lined with his original silver). Convinced by his ability to convert the last known Spark Lens to good, Daigo accepts the gift and becomes Tiga once again, survives his inner struggles and vanishes the darkness within. After leaving the Black Spark Lens in the hands of the dying Kamila, he eventually marries Rena Yamase, fellow GUTS member and longtime love interest.(Shin Asuka has also appeared at the last scene as Daigo was leaving earth,he was the guy who greeted him).
