I honestly just took slight inspiration from iron giant and that one robot from the movie 9

This abandoned milking machine lies dormant in the forgotten corners of a once-bustling laboratory, its sleek black exterior adorned with an array of buttons that hint at its advanced capabilities. Designed with precision and care, it was deemed too effective for public use, a prototype ahead of its time. Its unassuming appearance belies the power within; the large black box hides a symphony of sensual wonders.

A powerful cyborg Machina who is a lot more friendly than other Machina, opting to seduce and cooperate with humans than just breeding them.

A Queen class Machina who started the invasion of Saturn in a secret container from Pluto. Due to being at the start of the Machina outbreak, REPAIR hasn't been formed yet and human weaponry cannot harm Machina.

Shandra was designed and created in a high-tech laboratory as part of a secret government project to develop the next generation of aeromorphs. Her sleek body and advanced abilities were meant for reconnaissance and training purposes.
