Sandy Shocks is a robotic Pokémon with a body composed of three units that resemble ancient versions of Magnemite, all of which have yellow eyes. Unlike Magneton, each eye blinks independently of one another and not in unison. The top unit bears markings similar to tribal war paint as well as iron filings on its body and horseshoe magnets that resemble hair. The bottom units have only a single magnet each, which is elongated in a manner that makes them resemble legs; they are also covered with iron filings on their ends. Instead of floating like Magneton, it walks by bending these magnets. A series of screws with iron filings on the end floats between the two lower units, making it resemble a tail.
According to an article from a July issue of Occulture magazine, some scientists claim that Sandy Shocks is a Magneton that has lived for 10,000 years. It has allegedly been sighted numerous times in Paldea's more arid regions, but there are no reports of it ever having been caught. It is said to have an aggressive disposition and some people who have seen it claim to have been attacked. Sandy Shocks purportedly takes its name from a beast with a matching description in the Scarlet Book.
According to AI Sada, Sandy Shocks are ancient Pokémon and apparent relatives of Magneton that were brought to the present in the depths of Area Zero through the Time Machine created by the real Professor Sada 10 years ago.
- Sandy Shocks is the only known Paradox Pokémon to share its weight with its apparent relatives.
- It is also the only known ancient Pokémon not to weigh more than its apparent relatives.
Sandy Shocks is based on Magneton. The tufts around and on its body may be iron filings or ironsand (as suggested by its name and typing), and they resemble the messy and unkempt hair that cavemen are typically depicted to have. Its stilt-like legs and elongated tail may serve to reference dinosaurs of the Diplodocidae family. Its tail may also draw inspiration from transmission towers, with it specifically resembling an electrical insulator. Its presence among the ancient Paradox Pokémon despite being composed of modern objects may be a reference to out-of-place artifacts.
Its dual Electric/Ground typing may be a pun on electrical ground, due to it touching the ground rather than levitating like Magneton.
Sandy Shocks is literally sandy shocks. The word shock may refer to both a burst of electrical energy and a tuft of hair or fur.
Sunanokegawa can be taken literally as 砂の毛皮 suna no kegawa (sandy fur).
