He liked to think about the time he had spent in the vats, each one bigger than the last as he out-grew them. He missed the warmth most of all, especially now as he walked across the cold landscape towards the bunker. That's not to say he doesn't enjoy his life now, he is grateful towards his master for not only giving him this life, but for allowing him to pursue his dream. Once he had left the vats, he had shown a preference for mechanics and the way machines worked. Within a year of leaving the vats, he had made a mechanism that could walk by itself. It then took him another 3 days to make a machine that would obey instructions and not wander off of it's own accord.

As he approached the doorway of the bunker he had been instructed to open, he remembered the time he discovered that there was more "everything" outside the room he had been in for his early years: He had disassembled the door mechanism for parts and removed the door to use the metal and had then seen the corridor stretching away from him. It wasn't that the door had been locked, materials came in and his creations left. He had never questioned what was out there, all he needed was in the room or was brought to him. But now curiosity got the better of him, so he had created a machine with wheels and used it to explore this "new" world. That was when he had first met his master, his creator... The Scientist. He had been shown what he could achieve and what he had been "born" to do. He had worked happily for a long time after that meeting, building and repairing the various machines that were brought to him as plans or wrecks. Then one day, he had asked for one of his workshop assistants to pass him a new circular saw blade... The ork had thrown the blade "to" him and it had cut him in half at the waist. Unperturbed, and once stabilised, he had built his new legs... and they had been a significant improvement on his original legs.

Over time, he had added more and more to his mobile platform; useful tools etc... and now, here he was, striding over the battlefield, to open a door. The bunker held important equipment, so he was told, and that a gentler approach was required to open the door as the interior was not to be damaged in the process. He reached the door and studied the various locks. Two of the locks were simple, mechanical locks and these were easily opened with his electronic screwdriver device. Another, electrical, keypad lock was opened using his living-metal tentacle with the probe attachment. The magnetic lock required some drilling and finally being cut away with his welder. The door still did not move and he determined that there were two bolts on the inside of the door, these were cut through with his circular saw attachment. Finally, a gentle pull with his claw and the door opened.

As soon as the door was open, a small group of men attacked him, wielding crude weapons. The first man received a punch from the piston powered claw, this sent the man flying backwards with a caved-in chest. The second man was silenced with a rivet to the forehead, the hiss of it's mechanism always brought a smile to the Mechanic's face. The third swung his club, but this was caught by a tentacle and the man's arm was snipped off neatly, at the elbow, by another tentacle before the man was swept aside. The last man had stopped and was staring, wide-eyed, at the bloody slaughter in front of him, he had a damp patch in the front of his trousers. He was dismembered in the process of questioning and careful probing, but for the Mechanic, biology never held the same level of interest as machines did. The mechanic then reported that the bunker was open. He was eager to see what new toys he would have to play with inside.
