The Original Characters are the four main characters of the RGS (Richtofen's Grand Scheme) Timeline.
This group consists of four characters.
- "Tank" Dempsey - A Caucasian American, former U.S. Marine during World War II in the Pacific Theatre
- Nikolai Belinski - A Caucasian Russian, former member of the Red Army in the Western Fronts
- Takeo Masaki - A Japanese Asian, former member of the Japanese Imperial Army in the Pacific Theatre
- Edward Richtofen - A Caucasian German, former member of Group 935 and Illuminati in the Western Fronts, as a Nazi.
They are playable in Nacht Der Untoten (Black Ops only), Verruct (Tank only in World at War) (Black Ops only), Shi No Numa, Der Riese, Kino Der Toten, Ascension, Call of the Dead: Director's Cut, Shangri-La, and Moon.
They also make appearances in Call of the Dead (Console and PC), Green Run (Richtofen only), Nevada (Richtofen only), Great Leap Forward (Richtofen only), and Resolution 1295 (Richtofen only as Demonic Announcer or Zombie) for the RGS Timeline, and The Giant (Richtofen only), Der Eisendrache (Tank only), Zetsubou No Shima (Takeo only), Gorod Krovi (Nikolai only), and Revelations (child form) as part of the ABT (A Better Tomorrow) Timeline.
Richtofen and "Tank" make appearances as NPCs (Non-Playable Characters) in both Tutorial levels in Call of Duty: ZOMBIES and Call of Duty: Black Ops Zombies, respectively, teaching Rook the basic schematics of the game.
In Verruct, Tank is playable alongside the three other marines.
In Call of Duty: Black Ops II, Richtofen is the Demonic Announcer for the majority of the game. On Moon and Nuketown Zombies, Samantha Maxis is replaced by Edward Richtofen after completing the map's second major Easter Egg and reaching round 25, respectively.
