Nothing fancy, just some sprite editing. The idea was that just as Sindel gets ready to finish Kahn, his blood poured forth and Skarlet emerges to defend him. Not sure if that's how it looks. I'm quite pleased with Sindel but I think Skarlet could've been better. Those UMK3 ninja sprites aren't as versatile as I thought. I also didn't do a whole lot to the Pit III because the Pit III is perfect as is and its exclusion from MK9 was criminal.
These were the original sprites I used (the Skarlet sprite is Mileena using Jade's staff):
