No, that is not Sari Sumdac standing there!
It's actually Witchie-poo from Adam Warren's future Titans Scissors, Paper, Stone comic. This was a design I had done a couple years before TFA and Sari, to pitch the idea of using the SPS Titans in the Teen Titans cartoon at the time.
Now, all these years later, the Adam Warren Titans finally get to make their animated debut in a New Teen Titans short for DC Nation!
I don't remember Witchie-Poo being involved in my thought process with Sari at all. I don't recall referring back to it. Especially since in the very beginning, I don't think 1 knew Sari would be upgrading and aging up. Anyway, I guess the design, especially the color, made a memorable impact on my brain.
