Tobin Dax (played by Colm Meaney during Jadzia Dax's zhian'tara in the episode "Facets") was the second host of the Dax symbiont. (DS9: "Invasive Procedures") He had a child named Raifi, who caused him a number of difficulties over the years. (DS9: "Nor the Battle to the Strong")

He was a vegetarian and was known to bite his nails. (DS9: "Afterimage", "Facets")

Years later, Jadzia Dax felt that Tobin was socially inept and unimaginative, but he was a skilled engineer who was known for his intimate knowledge of phase coil inverters. Tobin once tried to learn some botany, but he didn't have much luck at it - he was the only Dax host to try it. (DS9: "The Siege", "The Wire", "The Siege of AR-558")

He also once tried his hand at learning magic tricks. (DS9: "Rejoined") One of his hobbies was developing an alternative proof to Fermat's last theorem. (DS9: "Facets")

Tobin once met the famous Cardassian poet Iloja of Prim while the latter was exiled on Vulcan. (DS9: "Destiny")

During Jadzia Dax's zhian'tara in 2371, Miles O'Brien embodied Tobin's memories and personality. When Curzon Dax undertook the ritual, he got Tobin drunk - for the first time in his existence. (DS9: "Facets")

Background

According to rumors, Tobin Dax was due to appear in an episode of Star Trek: Enterprise. Stargate SG-1 actor Michael Shanks, who was famed for playing Dr. Daniel Jackson on that show, was the fans' favorite to portray Tobin. Interestingly, Shanks had also auditions for the role of Shinzon in Star Trek Nemesis but lost out to Tom Hardy. ^{(citation needed • edit)}
