Star Trek: The Next Generation - Ranking Every Major Character Worst To Best

While Guinan is a static character throughout the series, she plays a pivotal role in the show. She is the character that all the other characters seem to orbit around. Which makes sense, she is the bartender after all.

Every major character comes to Guinan at some point for direction and guidance. These conversations always give the viewer a deeper understanding of the characters involved. She also has a unique relationship with Picard that’s only ever hinted at, and she even makes Q nervous. She's "fascinating" as certain Vulcans might say.
