|Doctor Ari Weiss|
|Portrayed by||William Atherton|
Doctor Ari Weiss was the head of the Passageway cryogenics company, who froze their clients at the moment of death to be revived in the future when technology had reached the point where they could be healed. He encountered the team when he claimed the body of Doctor Lester Hamilton after Hamilton was murdered, Hamilton's body being taken and frozen for future resurrection in accordance with his wishes despite the lack of a body hampering the team's ability to find his killer. Despite various legal complications as the team were eventually able to claim Hamilton's body- although initially deprived of his head-, the case was eventually solved, with Weiss reclaiming Hamilton's head and the body of Hamilton's wife (Who committed suicide after it was revealed that she had killed her husband to preserve him for future resurrection before a brain tumour killed him) ("Head Case").
