It's really not different from the comics at all, just directed at a younger audience.
I mean, it kinda is
I REALLY doubt THIS Starfire was being raped for 6 years, and that was a pretty "core" concept on her personality and backstory, she would be far more fucked up in the head if that was the case, and if she wasn't, then is a different version... which is totally OK... comics do that ALL THE TIME.
That background is just the classical version but not the her ONLY comics version, her newest one for example, Tamaran is a "free love" planet, so that's why she is the way she is regarding sex, no rape is mentioned (although not denied
), just the torture of the experiments she was forced to go through and how she awoke her powers because of it (in contrast of having her natural Tamaran abilities amplified in the classic version), her struggle this time was with
addiction, since the guards needed to drug her (a lot) to keep her newly discovered powers in control.
BTW Blackfire isn't even evil in this new version, she was "forced" so give Starfire
There are other versions too (Earth 1), superman style, where she was sent to earth as a baby and kept sedated for 16 years...
You know, comics doing comics stuff
So yeah, every version is a different version and sometimes they don't even have something in common.
From what i read in quick search the closest thing to rape in the show was Slade "abusing" Raven:
But even I think that a little exaggerated
