Okay, this one was pretty simple. I got the idea from a Star Trek short story from the book, "Star Trek: The New Voyages". The story, called "Mind-Sifter", details an adventure in which Kirk is subjected to the Klingon Mind-Sifter device and is deposited on 20th Century Earth, completely insane. While Kirk is treated in a 20th Century insane asylum, Spock is promoted to the rank of Captain, and put in command of the Enterprise.
Given that I already had a broken Spock figure, I went out and purchased a Kirk and commenced with a head swap. Pretty simple job. I ran the two figures heads under hot water to loosen the plastic, removed them from their original bodies, and then proceeded to attach the Spock head to the Kirk body. To finish it off, I gave the captain's body the Spock hands, and ta-da...Captain Spock, Original Series Style!
Please let me know what you guys think of him, and as always, comments are appreciated.
