Kazakku transformed into Numa O to trick Banban Akaza and was successful in slashing him. He led a whole fleet to Earth when the planet's DekaBase was compromised and turned against the Dekaranger, knowing that they are not capable of regaining control of their Dekabase, and that the greater good must be accomplished regardless of what sacrifices must be made as a result. However once the Dekaranger regain control of the Dekabase Banban Akaza warns of the trap set up by Rainian Agent Abrella, narrowly saving both him and the fleet in time.
