The Mechanic of Flesh

"'As it approached, what exactly it was became much clearer. It was almost like a centipede dragon - though with human legs instead of whatever insectoid legs such a creature would have. The wings - if you could call them that - were made of glass and solar panels, and reflected the moonlight. It had no head to speak of - instead, it had essentially a crow's nest sticking out of the back of it, from which its captain - The Mechanic - piloted it.' - Description of The Fleshmobile that was created from parts of AURANOS-1"

Summary
The Mechanic of Flesh is the former Mafioso under Boss Vinterlig for The Mafia. They were capable of creating strange fusions of metal and flesh that they could pilot, which they lovingly referred to as Fleshmobiles. They were also sometimes referred to as "The Hound" for their ability to smell souls, and then follow those scents for thousands of miles.

History
Their history before their being launched to the larger moon in one of Strangelove's rockets is unknown, though it is confirmed that the Red Right Hand had met them once before, which presumably allowed them to track Hand to AURANOS-1 and kill them while they fought alongside Umbra and 2573.

They then went back to Earth to report the good news to their boss, only to find them dead. They then went rogue, and followed their most recent scent - Warren's, which they had learned from 2573's friendship bracelets. They then fought Warren, Rakuen, and Star, after Star had a Book which formerly belonged to Hand. They were killed by Rakuen, whom smashed their head in, and the Fleshmobile ran off.

They have been revealed to be a distant relative of LADY CORDELIA.
