If Roberta wasn't niche enough!
This is the character Cybersix, from M rated Argentine comic titled... Cybersix.
For some reason, a few Canadian kid's show producers looked at this vulgar, gritty and explicit comic and thought "this is perfect to adapt for children's television" -- and they were right! Well, in my opinion. It was cancelled after the first season due to low viewership, but this was my all-time favourite show as a child. Perhaps I'm biased, but I'd argue that it holds up today.
Anyway, if you're reading all this, it likely doesn't matter since because the series is so niche, I can't see why anyone who isn't already familiar with it would be here!
Cheers.
