One way of representing a mechanical or electric being is it having a power cord for a tail or a tail that can function like a power cord. Like a regular power cord, this tail can be plugged into an outlet, or any sort of suitable electrical source, to draw energy. Usually does not have the issue of Cut the Juice (at least depending on the amount of energy the being has and can hold), although Achilles' Power Cord may come into play.

- Xurkitree is a collection of walking power cords, including its tail. It is known to plug itself to the ground to absorb energy.
- Meltan is a blob of liquid metal with a hex nut for a head and an electric wire for a tail. Strangely enough it's not an Electric-type like the others here, instead being pure Steel. Its evolution Melmetal has the same type of tail, if less visible.
