In a desperate attempt to escape the Red Sentient 5, Zemerik and Zug retreated into the Torborian Badlands, believing that Krytus would not follow them. Zug was damaged by an ion storm and offered his power core to Zemerik, who was then ambushed from behind by an Alpha Sark scout. Zemerik was then infected by the Alpha Code and offered his "worthless exo-skeleton" to the Alpha Code, but Battle Force 5 and the Red Sentient 5 intervened however. Zemerik's command codes were stolen by Battle Force 5 and Zemerik was then stabbed by Krytus, who proceeded to throw him into a pit. Later on, Zug's body was recovered by the Alpha Sark and dropped in the same pit. Zorax later reactivates Zemerik with the words "Arise my humble servant".
It is revealed that Zorax served Kromulax and was infecting Sark with the intent of building an army for the Karmordials. He and his Alpha Sark (including Zemerik) chased Battle Force 5 through many battle zones and managed to capture Sherman and Spinner but the rest of the team got away. Later Zorax attempted to make contact with Kromulax (likely to receive further orders), while Spinner showed Zemerik their handshake, which makes him recognize Spinner and get his memories back. Zemerik then shot Zorax claiming that he was nothing but a "False Prophet" and told the Zurk that they should follow their "true master." With these words Zemerik converted the remaining Zurk back to blue, thus ending the Alpha Sark threat
- It is possible that he is older than Zemerik as he serves Kromulax who created the Sentients. Zemerik was built by Krytus, who is Red Sentient.
- He has a similar head design to Tors-10.
