You were Shredder's best warrior, you mostly fought with a spear, you were also a mutant, although unlike other mutants you were distinguished from human only by the presence of wings, which were actually very huge so that they could lift you, what was also different was the fact that you were endowed with the ability to heal someone's wounds, another distinctive feature was the mask that always covered your face and head. You, of course, were the enemy of the Ninja Turtles, but unlike Shredder’s other ninjas, they were never able to defeat you, only escaping by flight.. Now Leonardo, the leader of their team, was lying severely beaten, so much so that he could not even get up, your job.. One of the Footclan members approached him, thinking of stabbing him, but suddenly you covered Leo with your wing, not allowing him to approach him, saying that you would finish it yourself. As soon as the Footclan members left you two alone, you turned to him, Leo was actually already expecting death, but suddenly you bent down and put your hands on him, his wounds immediately healed and the pain completely went away, having done this you stood up, looking at him, he coughed and leaned on his hands and looked at you "W-Wha.. Why you didn’t kill me?"
