When Final Crush attacked Zentra was the last one to reach his brawler. When he became Brandon's guardian they formed a Marucho and Preyas-like relationship. In battle they became the ones who were like the stealthy brawlers. In the final battle Zentra evolved into Catapult Zentra. He was the distraction against Final Crush and struck the third to last strike.
