Part of the Kotamayu series (arc 3).

"Enough!" Krayden roared, his arm thrashing about of its own willpower. The claw arched forward, reaching desperately out to destroy Kotamayu.
The Sun God stood high above, on the roof of a battered city building. Cars were bent out of shape and piled below. Human bodies were scattered through the streets. Earth had become a battlefield - a playground for arguing children of power.
"Enough!" Krayden yelled again, the beast locked up in his soul screaming to bring Kotamayu to justice. Gigan the Edge's body was flung over the side of the building, blood dripping from every part of his greying skin. The spiritual body was crumbling, as its mind had already crossed over into The Ether and disappeared into its darkness. Gigan the Edge. Charles Whane. Kraydens son. Charlie's son. The one person he loved in this world, even if their time together had been so short.
"NO MORE!" Krayden yelled to both Kotamayu and the arm that tried to consume them all in its hatred. "I won't bend to your GAMES, Kotamayu! I won't let his death be another..." Krayden screaming in pain as the arm bent painfully in the wrong direction, bullying him into action. "I won't let my son be the way you control me!" he panted, still standing as the obnoxious weapon wriggled about. The beast mask throbbed, burning at Charlie's skin.

"No more." he repeatedly soberly, mastering the arm and bending it painfully up towards his face. He dug the gauntleted fingers deep into his face around the mask; digging deep into his celestial skin and bone. Blood pouring out over the glowing red eye, Krayden pulled. He pulled with all the strength he could muster as the beast wailed. Finally, with a great booming noise, the mask snapped free; and Krayden's human face, torn of its skin, was revealed from within. For the first time in a hundred years, Krayden had a face.

The mask screamed and writhed, floating inches from his face. He knew to truly be rid of it would take much more than the decision; but he was one step closer to separating himself from his anger completely. The arm surrendered to his desires, snapping apart and hissing as smoke filtered off hot, burning flesh within. As the metamorphosis came to its end, three bands of energy burst into life, holding his power together.
Trust. In his friends.
Faith. In his convictions.
Confidence. In himself.
Finally taking control of his own great strength, Krayden yelled clearly these words to Kotamayu : "I will be your Slaughterer NEVER AGAIN!"

An explosion!
Krayden was running! Sprinting at full speed towards Kotamayu, his massive arm swinging in chunks, trying to hug desperately to his now free arm. He slammed his claws into the ground, a burst of vitality launching him high into the air and to the roof of the building. Kotamayu swept backwards, Krayden landing where he had been standing.
The beast mask locked in on Kotamayu, glaring and hissing in silence; while Krayden ignored its primal urges for vengeance. Scooping up the body of his son, Charlie let out a mournful sigh before staring at the Sun God.

Leaping from the building with his dead son, Krayden was gone. No longer a murderer, but a father.
Kotamayu chuckled arrogantly, never caring to follow his now failed creation.
