Mutant Charge
Zack returned to take over Earth, but he didn't expect Power Rangers to stop his 1st monster. He also had a rivalry with Joey Bloom, the Red Ranger because Joey was just like his most despised brother Walter so he wanted Joey's destruction the most. Every monster who was destroyed soul secretly went to a box that could make Zack stronger and he could bring them all back to life. In his final stand, he released the power of the souls and went on a raid against the Rangers but, it would be in vain as he was defeated by his rival the Red Ranger and sent to jail.

Kingdom Power
Zack's friend Zenix made a Hybrid monster so that he could break Zack out of jail so that he could get revenge. When Zack heard there were 2 team, he asked for the help of the Knight of Evil and together they defeated the 1st 9 Rangers, forcing them to call in the other Rangers. Together they not only destroyed the Hybrid but, sent Zack back to jail.
