This is a list of characters with articles or unnamed characters entries who were antagonists during Day 5.

Day 5's antagonists can be divided into two categories; the Dawn Brigade Russian separatists that acquired highly lethal Sentox gas, and the members of the Sentox nerve gas conspiracy whose plot to trick the separatists went awry.

Dawn Brigade separatists Edit

First cell Edit


Anton Beresch initiates the takeover of the Ontario Airport.

Anton Beresch: leader of the Dawn Brigade's plot at the Ontario Airport; martyred himself when nearing capture

  • Chevensky: terrorist and liaison between Beresch and Ivan Erwich at the Ontario Airport
  • Gunman #1: Beresch's lieutenant at the Ontario Airport
  • Ibrim: one of Beresch's terrorists at the Ontario Airport
  • Vlad: one of Beresch's terrorists
  • Ivan: one of Beresch's terrorists (not Ivan Erwich)
  • Ishmael: one of Beresch's terrorists
  • Achmed: one of Beresch's terrorists

Second cell Edit


Ivan Erwich, the man who activated the canisters and discovered the conspiracy.

Ivan Erwich: leader of this sub-cell; was secretly a plant among Beresch's hostages who was responsible for transferring out the gas canisters from the airport after Beresch's attack was used as a cover up; stabbed by Bierko

Primary cell Edit


The leader of the Dawn Brigade, Vladimir Bierko.

Vladimir Bierko: leader and financier of the Dawn Brigade, planned the later nerve gas attacks, the attack on the Suvarov motorcade and the Natalia takeover; neck snapped in self-defense by Jack Bauer

  • Collette Stenger: information broker who sold schematics of the Wilshire Gas Company to Bierko and framed Audrey Raines; incarcerated
  • Joseph Malina: arms dealer with connections to Henderson; sold information to help Bierko board the Natalia
  • Jenny McGill and Dwayne Thompkins: planned to sell Lynn McGill's keycard to Ostroff for money, but Ostroff murdered them instead to reprogram the key card to commit the Sentox attack

American Sentox nerve gas conspiracy participants Edit

Christopher Henderson & Omicron mercenariesEdit


Christopher Henderson, an important manager of the ground operations of the conspiracy.

Charles Logan's cabal and supporters Edit


The highest-ranking sponsors of the conspiracy, President Charles Logan and Graem Bauer.

President Charles Logan: a high level sponsor of the conspiracy; was exposed when Jack Bauer found a recording of a conversation between him and Henderson; after Miles Papazian destroyed this recording, Bauer, Chloe O'Brian, Mike Novick, Aaron Pierce, and Martha Logan worked together to expose him and remove him from office; arrested for murder and treason

  • Walt Cummings: Logan's Chief of Staff; involved in the early hours of the conspiracy with Nathanson; killed but framed as a suicide under orders from Graem and his associates, who planned to have him be the scapegoat of the plan from the beginning
    • Hank: an assassin hired by Cummings to eliminate Jack Bauer; failed, and killed by Jack; was entered into CTU by an unsuspecting Spenser Wolff
    • Schaeffer: Cummings' inside man within the terrorists; exposed then killed by either Ivan Erwich or his men
  • James Nathanson: Charles Logan's middleman and contact for Cummings; with the help of Russian Consul Anatoly Markov, he established communication with the separatists and supported Anton Beresch and his men; after being discovered, Nathanson cut a deal to gave Bauer a chip that lead to Omicron International and Henderson; killed by Ostroff's separatists
    • Spotter: a field operative of Nathanson who found Haas and his three men dead and was the middleman for communications between Haas and Nathanson

  • Justin Adams: a corrupt Secret Service agent loyal to President Logan; restrained Martha Logan; later was sent to murder Aaron Pierce, but was shot first by Martha Logan using his own gun
  • Miles Papazian: Homeland Security staffer; allegedly sexually harassed Shari Rothenberg several years ago; destroyed an important and incriminating audio recording of President Logan to gain favor and was rewarded with the promise of a high-ranking position at the White House; possibly arrested after Day 5

BXJ Technologies cabal members Edit

Graem Bauer: the leader of the four BXJ Technologies co-conspirators; directed President Logan through the cover-up in the last hours of the day; ordered Henderson to kill David Palmer and told Cheng Zhi that Jack is alive (after Logan's arrest, he was not implicated in the conspiracy and he remained at large; killed during Day 6 by his father Phillip)

  • Robert Joseph: one of Graem's three co-conspirators at BXJ
