The new voice makes him sound a lot like Alpha 5 (even restoring the familiar expression of 'Ai-yi-yi'), only it sounds more female than male. During the installation of the new voice circuitry, Alpha is asked to describe his mission in life as a test. Alpha recites his mission as follows: "My mission is to protect the Power Rangers. And their quest: To protect the universe from the forces of evil. One goal, one team, known as the Power Rangers."

After Thrax is defeated, Adam recruits him as an employee at his new dojo. Exactly how Alpha 6, last seen on Mirinoi with the Galaxy Rangers, wound up dismantled in Angel Grove, is never explained. There are questions about his reference to Zordon, whom he was never seen encountering beyond a cameo in "Passing the Torch." However, when he was sent inside the Universal Morphing Grid to fix it in Once A Ranger, the first question he asked was, "Ay-yi-yi, what would Zordon do?"
