A favorite song of ours to play, and to hear.
She's got six arms by default. One pair splits into two pairs, totalling eight arms.
Her legs may also split in two, granting four lower limbs.
Hardlight discs float around her, granting percussion and defensive blades.
When she taps her foot, a deep bass sound ripples through the ground, booming to the beat.
One head has a black-and-yellow CRT for eyes, a second head is a ghostly holographic. The second appears and disappears at will.
Her halo is a fusion generating tesla coil, in this case used as a Zeusaphone.
Her body is surrounded by a dynamic hard-light aura.
She can play any song, any instrument, in singular or multitude, for her chosen function is to play.
Her mane is hard-light, floating in the air as if she's underwater.

More on her later.

Vex/Aria, the Mare Automata, corrupted Ghost in the Shell, is one of my many characters, and few fursonas.
