5. Doctor Emmett Brown (Back To The Future Series)
Great Scott! No list of scientists would be complete without Doctor Brown bringing the power of 1.21 gigawatts. Goofy, eccentric, and your quintessential screwball, Emmett Lathrop Brown, better known as Doc to his friend Marty, is the creator of the flux capacitor after hitting his head and having a vision of the essential component of making time travel possible. Doc is driven by his passion for science and inventions, like his failed mind-reading device or his most famous creation, the DeLorean time machine. One of the most iconic images of cinematic history, the DeLorean time machine can travel back and forth through time after hitting 88 miles-per-hour. If you're going to mess with timelines, your mind-as-well do it in style. Accompanied by his dog, Einstein, Doc can be absent-minded and innocent, yet he has found himself at the wrong end of a deal with Libyan terrorists. Not wise to steal their plutonium. This physically animated character has spent his entire family fortune on his science, but funds have never resulted in a lack of imagination and ambition for Doc Brown.
