American actor who played Tolaris, the emotion-embracing Vulcan who draws T'Pol into a mind meld and then forces it on her, in the first-season Star Trek: Enterprise episode Fusion.
Enrique Murciano is an American actor who guest-starred in Star Trek: Enterprise shortly before becoming a regular on a long-running crime drama.
In Fusion he plays Tolaris, a member of a group of Vulcan wanderers who reject the total suppression of emotion. He takes an interest in T'Pol, urges her to stop her nightly meditation so that she can dream, and introduces her to the mind meld, a practice then all but forgotten.
When she tries to break off the meld he refuses to stop, and Archer afterwards goads him into revealing his violent temper before ordering the visitors to leave. The assault has lasting consequences for T'Pol, explored in Stigma.
