Chrono Morpher
From Power Rangers Universe
"Time for Time Force!”
The Chrono Morphers were created by the crime fighting unit of the future, Time Force. They lock on to a user's DNA so that only they, or one who's DNA matches closely enough to be related to the wearer, can use it to morph into a Time Force Ranger. The Chrono Morpher can also display holographic images, such as when communicating with a fellow Ranger. The Chrono Morphers could only be activated individually once the Red Chrono Morpher was activated.
