The Wrist Gauntlet was a small computer device worn, as its name implies, on the wrist, and featured numerous controls for various items of Predator technology, as well as a digitized, apparently numerical display. The Gauntlet was linked directly into a Predator's Bio-Mask and governed many of its functions, including its alternate vision modes. It also operated the user's Cloak and, in some cases, control a Yautja's Plasmacaster as well. The Gauntlet also acted as a power source for these tools, although it had only limited capacity and would become depleted with repeated use.However, despite the clearly advanced nature of the technology involved, Wrist Gauntlet could be recharged from any common power source, including junction boxes and standard human-manufactured battery units.
