6 is the visionary of the stitchpunks. He is constantly drawing what he sees in his visions, most prominately an odd device which he calls 'the source'. He has pen nibs for fingers, making it easy for him to fingerpaint.

He was rendered partially insane, as The Scientist already gave half of his artistic personality to The Machine. He tends to speak in confusing ways, which is the reason he is usually ignored. 9 is the first one to believe in 6, and figures out 6's ability to predict the future through his drawings. These images are used to riddle out the mysteries behind how and why the stitchpunks were created in the first place.

He is the fourth to die.
