Revenge of Vexecutor: A Cluster Prime Story

Revenge of Vexecutor: A Cluster Prime Story is a spin-off special of Alex Adventure. It aired on October 12, 2008. The special was going to be a setup for a new series, but Rob Renzetti's contract with Nickelodeon had expired before the series could be greenlit, so the special was the end of the franchise.

Synopsis
Three years after the events of Hero of the Year, a despairing Vexus has returned to Cluster Prime in surrender, as the ousted queen begins to question her own actions and goals. Her would-be transformation, unfortunately, is cut short when she is possessed by a corrupt spirit.

This spirit turns out to be that of "the Persecutor", an enigmatic, superpowered Cluster bot responsible for creating the anti-human philosophy that would later be espoused by much of Cluster Prime. His attempt several millennia prior to take over the planet resulted in the monarch of the time ordering the creation of a special "platinum" power chip, used to seal the Persecutor's powerful malevolent spirit away deep within the core of Cluster Prime itself. However, by indirectly manipulating outside events from inside the planet, he has played the entire universe to his advantage for thousands of years.

Now facing catastrophe at the hands of a Persecutor-possessed Vexus (or "Vexecutor"), Queen Vega is forced to call on the help of her self-exiled brother, Prince Zentraeus, to find the platinum chip originally used to defeat the Persecutor. Vexecutor's gambits and exploits, however, may destroy the two before they can even begin to look...

Background
Revenge of Vexecutor was initially conceived as an original story idea in August 2018 by Alex Adventure fan and avid TV Tropes reader Travis "Wedge" Hawkins.

Rather than adapting the action-centric format of the original Alex Adventure series, Hawkins has stated that his vision for the fic can be better described as a plot-heavy thriller that contains bouts of action. A proponent of adding new elements to Alex Adventure in an effort to keep it fresh for both old and new audiences (as seen in this post), his idea is to write one large story that can captivate audiences in ways the series never attempted.
