"Bell" (1950 - 15 March 1981) was a Soviet agent that defected to Perseus in the 1970s before being brainwashed by the CIA into helping them stop Perseus. He assisted in the capture of Anton Volkov, the infiltration of Zakarpatska Facility and discovery of Operation Greenlight, the discovery of Robert Aldrich in the US and Vadim Rudnik's agents across Europe, the infiltration of the Lubyanka, and the failed Cuba operation before undergoing an intense interrogation, where Bell realized he was brainwashed and manipulated by Russell Adler.
However, Bell realized that Perseus was insane and would doom the world should his plans succeed, so he instead told Adler that the Greenlight broadcast would come from the Solovetsky Islands. Bell was killed by Adler afterward at the orders of Emerson Black, to tie up loose ends.
