C. Rodgers was a maintenance worker assigned to the Mars City Underground on Mars.
When the player meets C. Rodgers in Doom 3, he correctly assumes that the player is looking for the missing scientist, Jonathan Ishii. He says that you shouldn't go looking for him, but refuses to reveal why. If the player persists in speaking to him, he will just refuse to talk about it.
During the demon invasion, when the player passes through the area where he last saw Rodgers, all that can be found are body parts scattered about, indicating he was killed.
- In the PC version of Doom 3, his body parts are scattered around his bloody workstation. However, in the Xbox version there are no body parts, but a trail of blood can be seen leading to the security office door which has bloody hand prints on it, which could possibly be Rodgers'.
- Unlike the other characters in the Underground, C. Rodgers will not flinch if you discharge your pistol.
