"Mako!!" Asami yelled. 

"I have returned to the mortal world. How long I've waited." The Beast of Fue said. 

It was a huge monster. Its eyes were like fire. It was steaming. It had cracks like magma. It shot out fire.  They dodged it. Korra bended it out of the way. 

"Sucess." One doctor said. 

"She has reawakened." The other one said. 

"Macko, come back!" Asami yelled.

"Shut up." The Beast of Fue said. 

It charged. Korra slapped it with air. The Beast of Fue dug her claws into the ground. She hissed. 

"Give us back my brother!" Bolin yelled throwing rocks. 

"The teenager is gone. His existence disappeared." She said.

She broke his rocks. 

"How do we stop it?!" Asami yelled. 

She glared at the Dread Doctors. She charged. She grabbed the main one.

"How can we get Macko back?!" She yelled. 

"You can't. He's gone." He answered. 

Asami's eyes swelled up with tears. She punched the mask off the Dread Doctors. She stares at his face. His face was corpse like. His eyes were a milky white. His skin was wrinkled and dark. His mouth dripped black ooze. Asami drew back. He quickly put his mask back on. 

They starred at the beast. It turned into black smoke that circled around. Where the Beast once stood. A woman now stood. Her hair was as red as fire. She wore a black robe. She opened her eyes. They were a flaming gold. 

"Su Yin." Korra said. 

"Yes." She responded.
