Resurrection gauntlet

The Resurrection Gauntlet was a metal gauntlet (also known as The Glove and jokingly dubbed the Risen Mitten by Ianto Jones) with the ability to bring the dead back to life for a limited time (TWEverything Changes''). It has a strange but unspecified connection to a knife made of the same metal. It was recovered from Cardiff Bay by Torchwood 3 some 40 years prior to Gwen Cooper joining Torchwood, and Jack Harkness theorised that whoever owned it wanted to be rid of it. Jack put Suzie Costello in charge of testing the glove. It transpired that those who used the glove could become obsessed with the possibility of being able to bring people back to life. After Suzie's suicided it was revealed that Suzie had been buying goldfish in bulk and killing them to test the Glove. Suzie's research showed that the glove was slightly radioactive and that the glove possesses "low psych levels" which allows it to directly respond to brain activity. It was later established it has an empathic link with its wearer, like "a rope from [the] heart to the glove" and that transfers the life force of the wearer to keep the dead alive. The Glove is more effective on recent, violent trauma victims, prompting Suzie Costello to murder several Cardiff residents in order to improve her proficiency in using it. Following Suzie's suicide, the Glove was placed in Jack's safe and sealed with a "DO NOT USE" tag.

It was later used to bring Suzie back to life. Gwen Cooper was the only one with the degree of empathy required to operate the glove without Suzie. When the glove was used on Suzie, Gwen's life force was slowly drained from her into Suzie and she even began developing the same wound as Suzie in the back of her head where Suzie's was. The only way to break this connection was to destroy the glove, which Toshiko Sato did, saving Gwen and killing Suzie again. However, Ianto Jones pointed out that "gloves come in pairs", implying that there may be another glove.
