Adam Park was the second Black Ranger of the 'modern era' of the Mighty Morphin Power Rangers and the Black Ninja Ranger of the Ninja Rangers. Two years later, Adam becomes Zeo Ranger IV - Green of the Zeo Rangers. During the events of Power Rangers Turbo, he briefly becomes the first Green Turbo Ranger of the Turbo Rangers. Retroactively, he is also referred to as the Mighty Morphin Black Ranger or Black Mighty Morphin Ranger, as well as Zeo Green Ranger or Green Zeo Ranger, though these are in reference to the show, as opposed to proper labels. He has also been labeled Turbo Green Ranger, a variation on his in-show label. Despite his apparent retirement following his tenure as a Turbo Ranger, Adam continued to support future teams of Power Rangers. A year later in Power Rangers in Space, he helped his successor, Carlos Vallerte recover his will to fight as the Black Ranger against Lizwizard, while temporary gaining access to his Black Ranger powers. Years later in Power Rangers Operation Overdrive, his powers would be completely restored by the Sentinel Knight. Adam is recruited by Sentinel Knight for conforming part of the Retro Rangers that Adam led helping the Overdrive Rangers against Thrax and his Evil Alliance.
