Uhura - Star Trek: The Original Series
When someone says the word "fierce," TOS Uhura is where my mind automatically goes -- thanks to the approximately two scenes the writers of the series deigned to allow her to shine. In "Space Seed," the one where Khan hijacks the Enterprise, Uhura refuses to follow his orders and gets slapped across the face. She takes it because she doesn't have a choice, but the sheer fury in her eyes terrified me even from my TV screen. And did you see her abs in "Mirror, Mirror?" That woman had muscles and curves, and she knew how to work them both -- not to mention wield a dagger to threaten her enemies. Nichelle Nichols knew how precious each and every one of her seconds on screen was, and she made the absolute most of them that she could. It's a damned shame she so rarely got to do more than say, "open hailing frequencies."
