According to the information provided, the novel "I signed in Dark Sparks at Otter" mentioned the three kings of the dark, including Golzan, Meerba, and Super Geb. Therefore, the strongest Three Dark Lords in Ultraman were Golzan, Meerba, and Super Geb. The plot of the novel is similar to the materialization of darkness. The protagonist obtains the power of Ultraman's star pattern in battle, but the power comes from the darkness. He has to fight against the darkness and finally become a man of justice.
