I saw some discussion upthread about Christine Chapel. I haven't seen the entire run of the original series in about two decades, but I seem to remember her being a major supporting character along with Sulu, Chekov and Uhura. Maybe I'm mistaken and she wasn't, but that's what I remember. I always wondered why she wasn't part of a "big 8". As for her not being included in the comics or the reboot, I figured it was because they may want to include her in a future movie.
