Ratchet

Autobot Ratchet tirelessly serves the Autobot cause; putting his versatile and unequaled medical skills to work as both a battlefield medic and doctor. He has devoted his career to the preservation of life in all its forms, and is selfless in protecting humans from the destruction often caused as a result of the Autobot / Decepticon war. Autobot Ratchet puts every fiber of his being into his job; extending his skills to make sure his fellow Autobots are kept as mentally healthy as possible. As a 4WD Rescue Vehicle, Autobot Rachet can travel over the roughest terrain and reach speeds up to 140 mph. He is an incredibly skilled and well-versed doctor, often limited more by time and possible lack of materials more than anything else. In battle, he's armed with an arc-welder blaster as well as a battle mace, which also can provide a small-localized force field shielding its user for brief durations. Autobot Ratchet often pushes himself to the point of physical exhaustion in performing his duties. He's usually so caught up in the healing of others, that he neglects his own maintenance.
