Pokemon riddle #4

I am small in stature but high in spark,

A glowing signal in the quiet dark.

I carry the whiskers of a feline friend,

But my long, black tail is where my wires end.

I’m a master of airwaves, a radio thief,

Communicating with others to bring them relief.

I share the typing of a giant from the moon,

A tiny golden orb that hums a static tune.

Who am I?

Hint: I'm an electric Pokémon/unlike richue!
