In-story information
Alter ego Seymour P. Fine

Sci-Fi is a character from the G.I. Joe: A Real American Hero comic books and animated series. He is the G.I. Joe Team's laser trooper and debuted in 1986.


His real name is Seymour P. Fine, and his rank is that of corporal E-4. Sci-Fi was born in Geraldine, Montana.

Sci-Fi's primary military specialty is infantry, and his secondary military specialty is electronics. Sci-Fi is known for being patient and taking his time, traits which aid him in aiming a laser over long distances for extended periods of time. When Sci-Fi braces his weapon and sights in on a target, he becomes as immobile as a rock, with no discernible movement of any kind. At a range of 2 1/2 miles, the impact spot of laser light will jump one hundred feet for every one thousandth of an inch movement at the source. Sci-Fi transcends mere stillness to hold that spot on target, long enough to burn through that source.

Sci-Fi took a leave of absence to complete his master's degree in electrical engineering, returning with the skill set necessary to enact unparalleled enhancements to the security systems in G.I. Joe headquarters.

As part of the Star Brigade aeronautical group, Sci-Fi was the designated pilot for the G.I. Joe Starfighter.

Sci-Fi makes an appearance in issue 25 of the Devil's Due G.I. Joe series. He is part of a demolitions team sent in to destroy EMP generators on Cobra Island. Led by the Joe Mercer, the team does so, but not without the deaths of Flash, Mainframe and the rookie Joe member, 'Hacker'. Jinx, another member of the team, survives.

Other works

Sci-Fi's figure is briefly featured in the fiction novel 6 Sick Hipsters. In the story, the character Paul Achting spent four years collecting G.I. Joe figures to set up a battle scene between the Joes and Cobra. As he imagined the characters in his head, he described four of the Joes on front lines of the battle: Hawk, Leatherneck, Wet Suit, and Sci-Fi "stood in procession, weapons raised, adrenaline pumping feverishly. Anxious for another victory over the dreaded Cobra". He described how "Sci-Fi's lackadaisical attitude was in check today. The laser trooper in the neon green jumpsuit was leading the charge. Out front, it would be his battle cry that the enemy would hear first".
