Tiberius Finch

Tiberius Finch was a surgeon working under Sir Henry Montague. He studied as a surgeon at the Royal College of Medicine, but failed to graduate after an event in his final year. He began work on the HMS Hades around 1869, where he studied the aliens that came through the Cardiff Space-Time Rift. He tried to breed the perfect soldier, using Blowfish as his minions. When Jack Harkness was captured after an attempted murder, he also studied Jack's immortality. When Torchwood Three investigated the HMS Hades, Finch tried to escape, but was killed by his creations after Jack released them. (TWN: The Baby Farmers)
