If you want to count random NPC's on the bridge who had one line, go ahead. That's not what I would call a character however.
TOS's Kyle, TNG's Rager, VOY's Vorik... They often got barely more than being a two-line walk on, enough to gain them a screen credit, though - plus future episodes, in which they finally got more to do. Every possibility that someone like Hannity would become a fully-blown character in the next movie.
Give me Ensign Rager over Wesley Crusher any day! In fact Lanei Chapman did a great job in Space Above and Beyond too - why didn't they bring Rager back for the movies? WHYYYYY?

Plus I'll watch Christine Rose in anything - she absolutely ruled in Heroes. T'Pau? Hell yeah!
