The main protagonist of the series is Nikko Zond, a young teen, whose father is involved in many different archaeological expeditions ranging from Antarctica to harsh deserts. Nikko is at first reluctant to participate in many of the adventures, but throughout the series, it would appear that there is a hidden destiny for Nikko.
In the episode “Skulls,” a mysterious figure (Conrad Dunn) appears out of nowhere, whom only Nikko can see, and guides Nikko. The episode ends with a crystal skull that is central to the plot of the episode modelled to reveal what someone would look like with skin and muscle added to that skull. The image formed matches the mysterious man who helped Nikko.
In the episode “Eternal,” Nikko is poisoned and the only cure is for him to drink water that heals, and assures eternal life. While it is unknown if he gained eternal life or not, he did heal.
In the final episode, he suffered from hallucinations that led him to find a fragment of an artifact called the “Ring of Truth”. Before the episode ends, he has another hallucination that reveals that the fragment of the “Ring” also joins together with another fragment that his father had acquired earlier in the series. The episode ends with Nikko displaying telekinetic powers: when he reaches for his soda, it slides across the table into his hand.
