  ok emily, 1st of all matrix revolutions is the 3rd movie not the 2nd 1) the oracle was black in the 1st and 2nd movies, she just had lighter skin and they had 2 switch actors in the 3rd movie because the lady who played the oracle died. 2) Well since the whole thing is just a computer programm, so is the oracle, and the agents are technically a program that has become a virus and is spreading itself around by turning all other programs into agents. hope that helps and im so bloody bored that i'll answer any questions rite now
