His strength is on par with Four Arms, and he has a large mace instead of a hand. He also has immense durability, able to withstand fire blasts and diamond shards.
Technorg appears in Grudge Match starting as an enemy of Ben and Kevin 11. Slix Vigma forced Ben and Kevin 11 to fight Technorg and they defeated him. Slix Vigma commanded Ben and Kevin to kill him and though Kevin 11 did not hesitate to do so, Ben stopped him. When they returned to their cell, Technorg, in contrast with his species's reputation for treachery, showed his honourable nature by bowing before Ben and Kevin 11 and declaring that he would serve Ben forever for sparing his life. With the help of Technorg and the other prisoners, Ben and Kevin were able to escape the cell.
Later, though the prisoners got into their escape pods and went to their home planets. Technorg did not, repeating to Upgrade that his life belonged to him but Upgrade pushed him into his escape pod. Just when Kevin 11 was about to keep Cannonbolt from escaping, Technorg pulled him away from his escape pod. Before his departure, Cannonbolt believed that he and Technorg were even. Technorg is last seen about to assault Kevin as the Megacruiser leaves for the next galaxy.
During the Ben 10 Week in a pop-up factoid, it was revealed that he defeated Kevin and escaped.
