Now here are the Top 10 worst fictional sisters.
10: Agatha (Twin-sister of Sophia)(From Double Double Toil and Trouble): She's a real witch! She locked her twin-sister into a mirror, then planned to bury the mirror.
09: Blackfire (Sister of Starfire)(From Teen Titans): She's another awful sister. Even her face pisses me off.
08: Shelley Mash (Sister of Stan Marsh)(From South Park): She's just a mean-spirited bimbo who never lets Stan do what he wants.
07: Katie Ka-Boom (Sister of... uh... whatever-her-brother's-name-is)(From Animaniacs): I love Animaniacs, but I have to admit, Katie Ka-Boom is my least favorite character from it. I think her brother will be a psychically broken man when he grows up...
06: Holly Waits (Sister of Joshua Waits)(From Troll 2): I already showed you that she's in my Top 10 most hated characters list. I think she's a bad sister too.
05: Sarah (Sister of Ed)(From Ed Edd n Eddy): This annoying, loud-mouthed little bitch is a horrible sister. She treats her brother like crap. What she deserves is a good spanking so she can't sit down for two weeks.
04: Drizella Tremaine (Sisters of Anastasia Tremaine and stepsister of Cinderella)(From Cinderella): Why couldn't she redeem herself too?
03: Vicky (Sister of Tootie)(From Fairly Odd Parents): Not only does she treat Timmy like sh** but she also torments her own sister. I'm sure her real father is the Devil.
02: Cree Lincoln (Sister of Abigail "Numbuh 5" Lincoln)(From Codename: Kids Next Door): Another bad sister.
01: Suzy Johnson (Sister of Jeremy Johnson)(From Phineas and Ferb): MEANEST LITTLE BITCHBAG EVER!!! What makes it worse is that Jeremy doesn't know what Suzy is doing to Candace... So yes, Suzy is the fictional sister that I despise the most!!!
