Predator and Prey

"Oh! Is this a riddle? I don't know Mei Xing, what is purple in the center, covered in red before turning to green and then blue and walks on two feet?" asked Sha Should with too much excitement. Especially since whatever it was was coming straight at me.

"I don't know," I replied with a sarcastic smile. "I was hoping you would. Are you sure that nothing will be able to find me in camouflage mode?" I continued as I watched the humanoid shape pause for a second before completely disappearing.

"Well, the Saalistaja might still be able to see you. Did you want me to change that? I probably could make you invisible to them as well, with a little help from Jun Li."
