Played By: Luke Perry and Shannen Doherty
 
It could have very well been Doherty's real life tension with 90210 creator's daughter Tori Spelling that made Brenda unlikeable enough to get kicked off the prime-time soap opera after its fourth season, but it was mostly her rookie mistakes when moving to Beverly Hills that caused her character to simply become an obstacle in getting Dylan and Kelly together. C'mon, Brenda even went as far to dye her hair blonde because she heard Dylan preferred blondes. Desperate much?
