The Battle of New York

The Mighty Morphin Clone Rangers were created by Violetta Delnosivo to cause chaos during the tenure in which the team they resemble. They were found out by Nancy Drew and her clue crew before being defeated by the very first and (what would end up being) very last teams in the Power Rangers franchise.

Post Mortem
Later, Lord Drakkon killed the version of Tommy Oliver of this dimension (Greater Saban-verse).
