Super Freak
I was a little worried about fighting Cheetah, as I was only a level 12 and I thought the level 20 thing seemed super daunting. It took me a few tries, but I beat her. Even got the credit challenge.
It took me one try, but I had her leveled up the ray after release, and had her with some epic gear. I almost lost though lol. Wish she had flipping moves like Canary and Aquaman.
