Limb Enhancers

"My limb enhancers! Where are my limb enhancers?!"

The "Limb Enhancers" were mechanical tools that were worn by Peridot. They appeared on her throughout most of her early appearances, and were confirmed to be separate body parts from her Gem's hologram in the episode "Catch and Release". The limb enhancers (except for her left foot, which Steven returned to her) are currently underwater near the Galaxy Warp, after having been disposed of by Amethyst.

Arms Attachments
The arms can create a tractor beam (used to levitate broken Warp Pad pieces, Pearl, and Steven), and also fire blasts of plasma.

Fingers
The fingers can create a screen, shaped by four fingers and operated with one. This can be used to operate machinery such as the Gem Warship by tracing different lines on the screen. The fingers also can generate jolts of electricity; and were also seen to rotate as helicopter blades. The touchpad can interface with Gem technology, including Warp Pad status, the Plug Robonoid (as a lift), remote Gem Warship operation, and for several uses in the Kindergarten. It is currently unknown how the fingers were able to float independently from the body, but when inactive, the fingers don't levitate anymore.

Legs
The legs increased Peridot's height, but appeared to have had no abilities otherwise.

Feet
In an emergency, the feet can be separated from the legs by pressing on the side of the foot. Peridot ejected her left foot during her escape in "Friend Ship". Peridot is able to scale vertical walls with relative ease when using her feet enhancers, as she ran straight up a wall in the Kindergarten in "Keeping it Together".
