Trying to find an old specific fill

[fun-mockingbird.livejournal.com]

Hi, I am looking for a fic I read a while back. It was one where Kirk finds out that his crew members are actually characters previously portrayed by the actors, Spock as Sylar, Uhura as her avatar character who reverse engineered herself into a human body, Scotty as a zombie, Bones as Cupid etc. Their abilities help save the day from time to time. I remember a particularly funny line where Spock finds out Chekov can time travel and goes off to meditate to avoid eating his brain. i have been going crazy trying to find it.
