Deanna Troi

Deanna Troi is Ship's Counsellor aboard the USS Enterprise. Being part Betazoid, Troi has empathic telepathic abilities, meaning that she can sense other people's emotions as well as detected when they are lying. This ability is useful for a Counsellor as it allows her to detect who needs help and when they are not telling the truth. It also allows her to detect the feelings of any potential enemies of the Enterprise, as well as detecting traps.

Her responsibilities greatly increased when she took on the rank of Commander, following in the footsteps of her friend Beverly Crusher, and allowing her to take command of the bridge if necessary.

Her mother is extremely annoying.

Troi dated Worf once and also had a thing for Riker, although no-one is really sure where they stand with each other. SHe also has a close friendship with Jean-Luc Picard.
