Okay if you seen the movie THE DARK KNIGHT RISES there is 3 thought out DC characters and they are villians. Okay this may refresh your memory and thoughts but imma get into it.

Cameos are people who are not known in the movie but yet appear in them.

1st. Cameo: Okay the first one is catwomens friend as you see her getting mugged by a man in the appartment hallway and catwomen saves her, but if you see how she looks and see her personality its a cameo and that is the well known"Harley Quinn" who is Jokers wife or Girlfriend IDK.Thats the first one.

2nd. Cameo: Okay this might be alittle hard but the 2 guys who worked for eayne enterprises and work for bane and in the scene where bane comes in when the two guys were talking the guy with his hair back and weird face and not the guy bane squeezes but the other guy is to be known as"The Riddler" hard to believe but it is.

3rd Cameo: Lastly this guy was in the first batman which was Batman Begins and he was the villian and in this film the judge for the death and exhile he is known as"Scarecrow" and that was pretty easy but yet simple.

Well i hope this helped to figure out people but yeah.Comment and do whatever.
