Amber

"She's 35 percent cyborg, trained by three different masters in killing, an unstoppable will to survive and 110 percent bent on revenge! Otherwise she is the least vile ninja of the 7th Division!"

-Random Ku clan ninja account of Amber

The last of Crimson Tracker's apprentices. Family and Fiancé were killed in a drug deal gone bad. Left to die near an erupting volcano, Amber crawled to safety even though all her limbs and parts of her torso were destroyed by lava. Found by Dr. Sun 5th Division commander she had her body remade into a killing machine. She eventually joined the 7th division to be trained by Crimson Tracker. She is still looking for the leader of the drug cartel to finally get her revenge.
