Ben 10: Secret of the Omnitrix

Ben 10: Secret of the Omnitrix is the first Ben 10 film released and a three part episode in the series.

Plot
Ben fights Dr. Animo, who has kidnapped Gwen and Grandpa Max, and threatens to release his DNA Bomb and de-evolutionize the world. Ben (as Heatblast, XLR8, or Eye Guy in different beginnings) rescues Max and Gwen, defeats Animo's latest invention, and sets off an error in the bomb by overloading the system. A DNA wave blows through and damages the Omnitrix. Ben changes into Grey Matter and knocks out Dr. Animo. Gwen, Ben, and Max then go to the shopping mall, but the Omnitrix releases a sudden energy burst, banning them from the mall.

Tetrax senses the Omnitrix and comes to Earth to warn Ben about it. The watch is in self-destruct mode and will destroy itself along with Ben (and the universe, but Tetrax does not reveal this until later). Ben, Tetrax, and his pilot, Gluto, travel across the galaxy to find Azmuth, the creator of the Omnitrix. Gwen soon appears on the ship to help Ben. They find the DNA signature of Azmuth in the Omnitrix and find that he is on Incarcecon, the prison planet.

After some time of searching on Incarcecon, Ben (in a costume with Gwen) thinks he spots Vilgax. He changes into Upchuck, and fights him, only to reveal that "Vilgax" is a female Chimera Sui Generis named Myaxx, who claims she created the Omnitrix. Ben, Gwen, and Tetrax get themselves into a street-fight. After escaping the fight, she reveals that she was Azmuth's assistant and directs Ben and the others to Xenon, where Azmuth lives. Their ship was intercepted and boarded by Vilgax and his Drones, but they were stopped by Ben, Gwen, Tetrax, Gluto, and Myaxx. In that action, Gluto was assumed dead.

When they got to Xenon, they were attacked by a group of wild Floraunas, where Gwen was captured by them and was assumed dead. After Ben's sadness, Tetrax told him the tragic story about him bringing Vilgax the final element he needed to destroy his home planet, Petropia. Even though transforming would accelerate the self-destruct, Ben transformed into Cannonbolt to break into Azmuth's lab, but Azmuth refused to help them. Ben then sees Vilgax, Sixsix, and their massive army of drones. Azmuth removed the main part of the Omnitrix, but Ben, Tetrax, and Myaxx still fought.

Soon, it was revealed that Gwen and Gluto were still alive and helped to battle. Azmuth then fixes the Omnitrix and unlocks Way Big. Ben then transforms into Way Big, defeats Vilgax's army of drones, grabs Vilgax, and throws him into space.

Ben is brought back to Earth, and finds out that zombies are attacking the mall. He then heads off to stop them.

Errors

 * When Ben and Gwen are fighting aliens on Incarcecon, right before the Tetramand destroys Tetrax's hoverboard, the Omnitrix is missing from Ben's wrist.
 * When Azmuth is re-inserting the Omnitrix dial, the "tower" of the dial is grey and green, as opposed to the standard black and green.
 * Tetrax calls Wildmutt a "Vulpin" instead of a "Vulpimancer."

Allusions

 * The controls that Tetrax uses to scan the Omnitrix for the DNA signature are almost identical to the computer that helps the "Precrime" officers in the movie Minority Report.
 * The scene where Ben runs away from a few Vilgax's Drones in the asteroid belt of Xenon resembles the level 2 of "Small Path" in the game "Star Fox 64," named "Into the Asteroid Field."

Trivia

 * This movie was intended to be the series finale of the original Ben 10 series.
 * In Store 23, there is a billboard of Ben 23's movie "Secret of the Hero Watch," which parallels "Secret of the Omnitrix."
