Scalpel (Transformers)

Scalpel, also known as The Doctor, is a minor antagonist from the Transformers series, specifically the live action film Revenge of the Fallen.

He is an extremely small Decepticon medic who speaks in a German accent.

History
In the film, after Megatron was killed, the Decepticons had Ravage capture the All Spark shard before heading out to Megatron's watery resting place. With the shard and the remains of a Decepticon warrior who unwillingly sacrificed himself, Scalpel resurrected their fallen leader.

Afterwards, the Decepticons were in hot pursuit of the human Sam Witwicky. Once Grindor captured him, he flew the boy over to the Decepticon's base, a small abandoned factory, before Megatron held Sam down as the Doctor readied to rip his brain apart as an interrogation method. However, Optimus Prime and his Autobot peers arrived just in time to save Sam and the Doctor was never seen again.
