Ultimate DC - Doomsday

Made for a Ultimate DC challenge at www.animotions.com

Here's the story:

The Ultimate was created by the ancient Kryptonians to be the Ultimate Warrior, undestructible, adaptable to be stronger with every defeat, but got out of control and nearly wiped all traces of civilization. Thanks to the combined effort of the greatest minds of Krypton, the creature was captured, trapped inside the Phantom Zone held down to a Kryptonite meteorite by kryptonite energized chains, linked to the device's control. Those minds became the first Elders of Krypton, and the planet knew peace for a thousand years.
While searching a suitable location for his secret base, General Zod, a renegade militarist, came across a hidden ancient Phantom Zone device. Inside it, he found The Ultimate.
Zod took the device, and brought it to the Council of the Elders under the excuse to have the Elders examine it, only to switch places with the creature and let it run loose. He and his most trusted lieutenants hid in the Phantom Zone while The Ultimate obliterated the Capitol City, killing everyone in it's path. But the creature, not as mindless as it seemed, knew what the devide was and the first thing it made was to toss it into space in a fit of anger. The Elders were the first to fall. One by one, the buildings of Krypton's Capitol City were tore down, and the Kryptonians killed by the Ultimate.
This was the moment that Jor-El, witnessing the destruction around him sent his son, Kal-El on a rocket away from Krypton, as The Ultimate was unstoppable. The Kryptonian supercomputer Brainiac left the planet shortly afterwards, to keep an eye on Jor-El's son, and found the Phantom Zone device. Deeming them the only survivors of Krypton, Brainic freed Zod and his crew. They took control and reprogrammed Brainiac to find a suitable planet to conquer as New Krypton.
Finally, The Ultimate killed all the people in the planet, and when then turned his rage and hatred of Kryptonian on the planet itself, pounding the floor with such strenght that it began to crack. At that time, Zod commanded Brainiac to use it's weaponry against the creature, and when the explosives warheads mixed with the fumes of the molten Krytonian Core the planet exploded.
The Ultimate was launched into deep space, unconcious, to be found 30 years later by Siniestro. The evil Green Lantern knew what the creature was and decided to drop it into the third planet of the sol system, to erradicate the main obstacule to start his conquest of the planet... Superman.
It's a little long, but I think it's worth it I tried to tie it to the Ultimate DC stories that Wizard made some time ago, while being somewhat faithfull to the character.
