When Daphne goes to meet Samir Mellouk after their theft of the Mona Lisa from The Louvre, Mellouk's assigner, Dr. Livitz, meets her. He doesn't reveal his name to her but says that Samir was unreliable and would no longer be working for his group. He then offers Daphne a job and hands her a folder containing a photo of Kaito Nakamura.
Dr. Livitz and Arthur Petrelli greet Mohinder when he comes to the Pinehearst building. Later, Dr. Livitz looks on as Mohinder is about to inject Peter with the formula. Sylar arrives and telekinetically throws both Mohinder and Dr. Livitz against the wall. Dr. Livitz is impaled on some wall fixtures, killing him.
Livitz is the attending physician when Arthur Petrelli is brought in after his "heart attack." He lies to Angela and Nathan, informing them Arthur is dead. He receives telepathic orders from Arthur saying to substitute a body for cremation, and informs Arthur that the poison caused permanent damage to his peripheral nervous system, causing paralysis. Later, Dr. Livitz attends Arthur's funeral at the Petrelli mansion and speaks with the priest there.
- The name of Dr. Livitz for Arthur's doctor was revealed by writer Chuck Kim in the commentary for the episode Dying of the Light. According to Chuck, the character is named after a friend of Oliver Grigsby.
- In the October 23, 2008 issue of CBR's Behind the Eclipse, it was confirmed that Arthur's doctor is the same person who hired Daphne in Paris (Our Lady of Blessed Acceleration, Part 1).
