I do not own Danny Phantom or Teen Titans. If I did, they'd still be on the air.

"I was protected by the monks of Azarath, I was raised by my friends." The massive demon continued to squirm in pain as he fell onto his knees, the white energy snaking along his body as he continued to scream. "They are my family, this is my home, and YOU ARE NOT WELCOME HERE!" A young woman, dressed in a white leotard and white cloak rose to the air, white magic swirling around her and shining from the red chakra stone on her forehead. "Azarath Metrion ZINTHOS!"

The woman was engulfed in the white light as it took the form of a massive white bird. The demon could only gape in horror before he too was engulfed in the white energy. A final scream escaped his mouth as the last of the bird transformed into a column of light, vaporizing the demon. The white light continued to spread until it engulfed the entire planet, changing the desolate landscape back to the way it was before his arrival.

Clockwork turned away from the viewing window as the last image flickered away, chuckling to himself as he moved through the halls of his citadel. No matter how many times it happened, it always brought a smile to his face to see someone challenge a destiny imposed upon them and overcome it. It was that very fact that caused him to look at the high-tech cylinder behind a shield of ectoplasmic energy. It could be argued that it was physical proof that the future wasn't a linear thing, that it was something that could take any form and go in any direction. 'Like a parade watching from above.'

Red lightning began appearing from behind the age-shifting ghost, scorching the smooth floor behind him. Clockwork's face remained calm as a silhouette appeared from the smoke, the four blood-red eyes glaring at him. "Clockwork," growled the figure in a deep, gravelly voice as he stepped out from the smoke. The age-shifting ghost said nothing as the figure approached him.

"Why have you summoned me to this realm?" asked the red skinned creature as he glared down on the toddler. "You know as well as I do that you can't be summoned to a realm without a Gem of Skath. You're daughter has merely done what you never believed was possible." The demon let out an inhuman roar as he lunged towards the master of time.

Clockwork did nothing as the creature grabbed his shoulders and brought him to eye level. "No one can kill me ghost!" growled the demon, fire seeming to erupt from his eyes. Clockwork merely looked back into them with his calm crimson eyes. The tension between them was broken when a dark laugh erupted from behind Clockwork.

"Who dares to laugh at Trigon the Terrible?" growled the demon ghost as he looked around for the source of the outburst. The laughter continued for a few moments dying out. "My guess would be my new roommate," said the voice as he chuckled again. Trigon let go of Clockwork and made his way over to the small ecto-shield and growled. "Don't think you are protected from my wrath because of this pitiful shield. I will escape this realm and that ungrateful wench will pay."

This enticed another laughing fit from the container, causing the demon to snarl at it again. "You won't be out for long before you share this fate," said the voice in a matter-of-fact tone. It was Trigon's turn to laugh. "What makes you think someone could trap me in such a ridiculous object?" "Because," said the voice, "there are only two definite locations with portals you can escape from, and both of them are protected by a ghost-human hybrid."

The demon let out a savage roar as he tore through the ectoplasmic shield and grabbed the metal cylinder in hands. "What makes you think a half ghost can defeat Trigon the Terrible?" growled the demon as his burning red eyes narrowed at the device.

"Because he can change the world."

Trigon turned to look at Clockwork as the words left his lips. A snarl grew on his face while a smile graced Clockwork's. "But with my help, you can get the revenge you so desire." Trigon looked back to the metal cylinder in his hands, a low growl emanating from his throat. "Let me out and the world will be yours again."

"And what would you ask of me if I grant you your freedom?" asked the demon ghost, his interest peaked. "A simple matter, you help me kill the one who defeated me and I'll return the favor. Then we just do whatever we want without interfering with each other." Trigon stared at the cylinder for what seemed like an eternity, contemplating the offer.

"Very well," said the demon as he reached for the shining cap at the top of the cylinder. A green blast of energy struck the demon in the back, causing him to bellow in pain and drop the container. Turning around, he saw several Clockworks, each dressed up in different outfits from different eras in time. The original Clockwork flew over to the demon and grabbed the cylinder, ripping it out of his hands. Letting out a massive roar, Trigon raised a hand towards them, red energy whips firing from his hands. The dark magic bound each of the Clockworks, causing them all to fall to the ground. The metal cylinder hovered in the air, surrounded by red energy, and flew back into Trigon's hands. The demon ghost grinned as he removed the silvery lid, causing a white flame to shoot out of the container.

The white flames congealed in front of the demon ghost before taking a humanoid form. The ghost stood for a moment, the white fire that made up his hair flickering in the air. His white cape hid most of his features until the ghost stretched, revealing the costume underneath.

Black spandex covered most of his body, with the exclusion of the white of his belt, boots, and arms. A white D outlining a P sat in the middle of his chest, completing the costume. His face was the only place his outfit didn't cover, revealing the spirit's blue skin and white goatee. Opening his eyes, he looked into the demon ghost's eyes with his own red eyes, a serious look on his face.

"What is your name?" growled Trigon as he eyed the ghost over. "Dan, Dan Phantom." The blue skinned ghost extended his hand and grabbed the metal cylinder from the demon ghost's hands. Stepping away, Dark Phantom aimed the device at each of the Clockworks, sucking them up in a flash of blue light. "Now, how to take care of both of our problems." Dan brought up one of his hands to his chin as he began to ponder, until a wicked smile appeared on his face. "I think a play date is in order." A smile grew on Trigon's face. "A most amusing idea. A most amusing idea indeed."
