Consumer of All (Morphing reader x RWBY)

Thunder rumbled across the skies above Vale. In a mad rush, Fenrir called upon Hecate to smite his enemies. Although there were only three, Hecate's power was not so pinpoint when so hurriedly called upon. She hastily threw a bolt of red lightning at the Amity Colosseum. In her haste and Fenrir's rage, the entire colosseum was annihilated in a single bolt. 

All but Fenrir died.

He hovered in the air, flapping his wings as he gazed coldly upon the smoking remains of the colosseum as it fell to the ground thousands of feet below. However, his bloodlust and wrath were not quenched. He didn't even think about his dead teammates. All he could think of was further carnage. 

Fenrir descended upon the city of Vale and razed it to the ground. Hunters and forces of Atlas which arrived in the evening tried to stop him, but he was untouchable to their weaponry. Bullets bounced off his skin. Blades broke upon his being. Ozpin and Ironwood could only despair as the enraged demon annihilated everything in its wake.

Why was this happening, though? What set him off so badly that he could become so heartless and cold?

There was a simple answer. In outer space, upon a meteor, sat two figures. One was a large humanoid with a shiny black exoskeleton and great wings, clearly a demon by his horns. He radiated a dark and deprived aura. The other was a golden figure so bright that mortal eyes could not behold it. For those who could, it was a maiden of light so beautiful it would snatch one's heart on sight. White feathery wings billowed behind her along with her long and flowing green hair. 

"Dost thou sense it, Akros? Another demon has fallen to hatred..." 

"I... sense it... my lady. Who... is it?"

"A foolish mortal demon. He shall be consumed by himself... a witless monster... what a rancid scene to behold indeed," The angel scrunched her beautiful nose in contempt. "Let us remain here no longer. I need not view this."

"Oh, no you don't!" 

The angel gasped as a scythe nearly tore her head off. She ducked at the last moment and leapt off the meteor. "Who dares?!"

"I dare, bitch," Hecate snarled. Golden flame and red lightning surged around her, distorting reality itself with the raw power behind her magic. No, it wasn't magic. She had authority over the plasma itself. She wasn't using magic, she was bending matter to her will. "I won't forgive you! First, you shackle my master! If that wasn't enough, you ruined my entertainment! I swear I'll kill you this time, Linnea!"

"Oh, dear Hecate..." Linnea grinned at her. "Thou can deliver as many threats as thy have scales, it maketh no difference. Akros!"

"Yes..." The black humanoid spread his wings and got between Hecate and Linnea. The former grit her teeth in frustration and hesitation while the latter laughed wickedly. 

"Thine attempts to fell me are no more significant than the wails of a dying animal," Linnea taunted. "Thou must reflect on thy actions. I shall let thou live. I am satisfied at the moment. Come along, Akros."

She opened a portal for Akros to pass through before leaving herself. After they left, Hecate stashed her scythe in her separate space and began to weep uncontrollably. 

"Damn it... damn it! I can't fight him, no matter how hard I try!" She bawled into her hands. "Why must fate be so cruel to me? To my dearest master? Why...?"

Hecate then realized that Fenrir was still running rampant on Remnant. She wiped her eyes and descended back into the atmosphere as fast as she could. She wouldn't lose another ally. Akros' miserable state reminded her how important it was to treasure what she had left.
