(When the personalities of all Ultraman Tiga's abilities change)
Twenty years ago, light came to the world and then disappeared quietly after saving the world.
That day, countless meteorites fell, darkness engulfed the earth, and mankind was on the verge of extinction. A man turned into light and transformed into a giant in the sky. With a gentle wave of his hand, he drove away the doomsday. No one knows where he came from or where he went. There is only one sentence, "Everyone can become light", which has been circulated in the ruins for twenty years.
Twenty years later, darkness awakens again.
A black giant stepped out of the seal and awakened the ancient monster sleeping underground. When Golzan and Melba trampled on the earth again, mankind finally discovered that the war they thought they had won has never really ended.
