Scalpel

The tiny Scalpel, also known as "the Doctor", looks harmless enough with his big, inquisitive eyes. But beware—in the world of the Transformers, things are not what they seem! Scalpel has vast databases of anatomical and mechanical knowledge, being familiar with most species in the galaxy. He's extremely adept at getting to the root of a problem and can handily disassemble most technological devices... or life-forms. Unfortunately, when he goes to put them back together, he always has a few parts left over. This has left most of the Decepticons reluctant to come to him for care, in spite of his duties as their field medic.
