4000. Montgomery "Scotty" Scott

Montgomery "Scotty" Scott is a Scottish engineer in the Star Trek media franchise. First portrayed by James Doohan in the original Star Trek series, Scotty also appears in the animated Star Trek series, seven Star Trek movies, the Star Trek: The Next Generation episode "Relics", and in numerous books, comics, and video games. Simon Pegg assumed the character for the 2009 film Star Trek.

Montgomery Scott was born in Linlithgow, Scotland in 2222. Doohan claimed to have based Scotty's accent on an Aberdeen accent he once heard. During the events of Star Trek, Scotty holds the rank of lieutenant commander and serves as the Enterprise's second officer and "miracle worker" chief engineer. Scotty's technical knowledge and skill allow him to devise unconventional and effective last-minute solutions to dire problems. Scotty's identity is strongly connected to the Enterprise itself, and the character often takes a paternal attitude toward the ship. He is frequently the liaison between Captain James T. Kirk's (William Shatner) ambitious tactical plans and what is technically feasible in the realm of the starship's capabilities. Although he sometimes commands the ship when both Captain Kirk and first officer Spock (Leonard Nimoy) are off the ship (as third senior officer), Scotty asserts in the TNG episode "Relics" that he "never wanted to be anything else but an engineer".

Scotty oversaw the Enterprise's refit prior to the events of Star Trek: The Motion Picture (1979), and is part of the crew when the Enterprise confronts Khan Noonien Singh (Ricardo Montalbán) in Star Trek II: The Wrath of Khan (1982). Although not stated when this occurred in the original release of the film, Peter Preston, who dies with Scotty at his bedside, was Scotty's nephew. Scotty was promoted to captain of engineering of the USS Excelsior in Star Trek III: The Search for Spock (1984), Scotty sabotages his new ship and helps Kirk steal the Enterprise to rescue Spock. Scotty joins Kirk's crew aboard the USS Enterprise-A at the end of Star Trek IV: The Voyage Home (1986). In Star Trek V: The Final Frontier, he helps Kirk, Spock and Dr. Leonard McCoy (DeForest Kelley) escape the brig and retake the hijacked Enterprise. Scotty kills Colonel West (René Auberjonois) before the latter can assassinate the Federation president (Kurtwood Smith) in Star Trek VI: The Undiscovered Country (1991). Scotty joins Kirk and Pavel Chekov (Walter Koenig) for the USS Enterprise-B's maiden voyage in Star Trek Generations (1994), saving the ship through technical wizardry.
Scotty was aboard a transport shuttle en route to a retirement colony when it crashed into a Dyson sphere; stranded, he set the transporter to cycle indefinitely and "stored" himself in the buffer for decades before being recovered by the USS Enterprise-D crew in "Relics". A "relic" no longer able to serve effectively as an engineer and struggling to acclimate to 24th-century life, Scotty nevertheless manages to help save the Enterprise-D through technical know-how and chicanery.
