Made for Ramox/Bootleg's series, Scrapmaker is my robotic character.
I'll try to make his backstory as short as possible...

When Scrapmaker was first created, he was a nameless repair drone, the only notable part of hia construction being the welding dvice mounted on his right arm. One day, though, the Corrupt Machines attacked the facility Scrapmaker was positioned in, killing his creator and all other drones in the building. Scrapmaker managed to survive by hiding under a random pile of scrap and rubble. After the Corrupt Machines left, he used his welding tool and began to upgrade his own armor, body, and weaponry by using the metal corpses of his fallen drone comrades.

Then, he thought about the event that just happened, and came to the conclusion that he must direct the rest of his life to one saying- "Survival of the Fittest". Soon after, he began killing other robots for sport, collecting their armor and weapons to upgrade himself. In fact, he even has a secret junk yard base, where the scrapped metal bodies of his victims stay. Scrapmaker is also a very skilled fighter, and has added technology to his arms that allows his arms to form 2 different weapons: a gun mode and a blade mode. Scrapmaker prefers to fight dirty though, and sides with no one. He's basically a rogue that kills for sport.

(There's joints on his arms in the normal mode that are supposed to make his arms transforming look more realistic when he's being animated.)
