Though Scalpel "The Doctor" looks harmless, he is very evil. He's pretty much the Decepticon version of Perceptor, but more sadistic, cruel, and smaller. He tortures people so much they die, then brings them back to life so he can do it again.
Revenge of the Fallen film
The Doctor went to the the bottom of the Laurentian Abyss along with Long Haul, Rampage, Ravage, Mixmaster and the little one. Using the All Spark fragment stolen by Ravage, the Doctor orders the Decepticons to kill the little one to obtain the parts to repair Megatron's body.
He later waits in the warehouse where Grindor captured and took Sam, Mikaela and Leo. Megatron orders him to extract the knowledge of the Cybertonian language Sam had been seeing. He was able to probe into his nose and brain, but demanded to take out the brain for a full scan. However, he was interrupted in his preparation to drill into Sam's brain when Bumblebee and Optimus came to the rescue and had a brief battle.
Scalpel (Scout, 2009)
- Scalpel transforms into a microscope. In microscope mode, he isn't life sized, since he is very tiny for a microscope. However, his humanoid form is almost a perfect life-sized version of the one in the Revenge of the Fallen film.
- His fate isn't shown in the film, but the novelization and comic depict him being destroyed by Optimus Prime upon arrival.
- When Scalpel ordered the others to kill "zeh little one", he was the smallest Transformer in the area... perhaps he has issues. Scale issues.
- Someone drew scalpel in animated style.
