That's actually a really difficult question because I have two characters that I greatly enjoy: Data and Worf.

And what makes this so hard is that my absolute favorite part about both of these characters is their interactions with each other, particularly when they share knowing "those crazy humans and whatever they're up to now" glances.

So for a while I was leaning toward Worf because of that one time he said "You may now give birth" to Keiko O'Brien, but then again, he had that episode where he dressed like a ninja and tried to make the colony of peace-loving Klingons more belligerent.

Data, on the other hand, provided me with more regular comic relief and "straight man" value, so I think I'm going to have to go with Data.

Yep, Data.
