The Hand Behind The Scene.

Legion-7 was very angry. 

"That thief stole my prize." He said in anger. "She stole the title of child of the plane."

Razor was his prey. He was supposed to infect the boy with his soul virus. But She stole him from his hands. The tide of the situation turned with the change in title. He began losing the plane as soon as he lost the title. 

The major issue is that Kilorita is too powerful now. She can also sense every being that has been parasitized by him so can direct her immense power to the right place. She was able to quickly cut off his avenues of attack at the will of the plane. 

That's the first thing she did. She targeted the clones he made to attack the Will of the plane above the other infected.
