Soft Machine is an armored humanoid figure with robotic eyes and no visible mouth or nose. Most of its entire body is covered in a series of large spiked nubs, with bullet-shaped objects protruding from the top of its head. In its right hand, the Stand holds a short, dagger-like rapier that is utilized for its ability.
As it only needs one stab to completely disable its victims, Soft Machine's puzzling ability makes its ambushes fearsome. But once in the open, its mediocre fighting abilities are clear.
Its only notable feature is that it is equipped with a short rapier that can act as a normal weapon if need be. With its sword, Soft Machine managed to scratch Moody Blues' hand.
Soft Machine is capable of literally deflating people (including its User) and objects by stabbing them with its small rapier.
Deflated people and objects have 'air' visibly escape from the puncture in their bodies and eventually become deflated, limp and rubbery, akin to a balloon. Deflated people also have their clothes deflated, and despite their state, are kept alive.
The deflated victims can then be pulled through small spaces, such as pipes, often by means of stretching them out. Among the best examples of the ability's usage is when Soft Machine covered a ship with the deflated version of an identical ship, allowing Zucchero to hide between the two layers and stay undetected.
