I've got to find a new picture, that was my stern look...

  I  can manage a good one, but it's not my usual look :)

a brilliant inventor and technician who designs advanced weaponry for criminals and sometimes undertakes crimes of his own. As the Tinkerer, he runs an underground fix-it shop disguised as a radio repair shop.

?The Tinkerer has a genius intellect, with extensive knowledge in a wide variety of scientific disciplines. He has a high degree of expertise in the design and manufacture of inventive weapons and devices derived from pre-existing technologies. The Tinkerer has invented a wide variety of scientific and technological devices, and often has access to these devices as needed.

?? Lol, WikipediA ;)

Yes, I will ask things of you, perhaps some that will be hard for you, but rest assured I would never do any harm. I'm not someone who does things without thought and consideration. I don't get off on hurting people. I can cause pain when appropriate, but I'd rather see you writhe as I control you. .
