Rise doesn't seem to understand the franchise much, so why wouldn't they screw that part up, too.
Honestly, those connections were so convoluted with Karai now somehow being Yoshi/Splinter's ancestor AND Shredder's daughter, I'm not sure it quite dawned on me that the name didn't even make sense. Either that or I quickly forgot because it was, for me, a pretty forgettable show.
Though I will say that I wish they'd made more use of this Karai as an ancestral spirit. Having her appear off and on
throughout the series, guiding the Turtles when Splinter would not, might have given the show more weight and an interesting twist to balance out it trying to be so derpy otherwise.
