Profile: First Aid hates seeing a machine in pain -even if the machine itself is unaware that it's hurting.  He's been known to fix broken street lamps and administer water to overheated cars on his travels.  This often delays him in performing his normal duties but his fellow Protectobots rarely take him to task over it.  He's simply too compassionate!  He's also overly cautious -he'll restrict an Autobot to the repair bay for a mere faulty directional signal.  Although his comrades sometimes take issue with First Aid's judgment in such cases, they know the quite, hard-working doctor is only looking out for their best interests, and that is a comforting thought.

Abilities:  In vehicle form, First Aid can travel at 140 mph with a range of 500 miles.  He carries a dual-barreled decrystalizer cannon, which disrupts the crystaline structure of most metals, reducing  their tensile strength and making them vulnerable to fracture.  In robot mode, he carries a photon pistol that shoots light-bursts with the equivalent brightness of 5,000 watt bulbs  enough to temporarily blind all but those whose optical sensors are the most heavily shielded.  Each of his fists can emit a high-temperature narrow laser beam which he uses for welding during surgical procedures.  He combines with his fellow Protectobots to form the giant robot known as Defensor.

Weaknesses: Other than his aforementioned tendency to be distracted, First Aid occasionally suffers from electrical systems breakdowns, particularly when he uses his decrystalizer cannon.  This sometimes leaves him unable to perform simple functions, such as turning on his lights, or worse, leaves him completely immobilized.
