The Vampire Strikes Back

The Vampire Strikes Back is the forty-eighth episode of Ben 10: Omniverse.

Plot
Ben, Rook, Rad, and Hobble are seen in the Lovely Duck, where Rad has almost repaired his ship. Meanwhile, Zs'Skayr is seen using the power of the Alpha Rune to revive Lord Transyl, a Vladat. Dr. Viktor is not happy with this, as Vladats were the predators of Transylians and they used them as slaves. Zs'Skayr then orders Kuphulu to pull down a lever and then Lord Transyl gets resurrected. Meanwhile Ben, Rad, Rook, and Hobble are leaving Anur Transyl when suddenly the Omnitrix gets a signal of a new DNA sample somewhere on Anur Transyl. Ben tells Rad to go back to Anur Transyl so that he can obtain this new DNA, but Rad opens the ship and Ben gets sucked into space. Ben transforms into Astrodactyl to save himself while Rook convinces Rad to go back to get Ben.

At Zs'Skayr's castle, Lord Transyl suddenly attacks Kuphulu and Viktor to feed himself, but Zs'Skayr defeats Transyl and convinces him to help him carry out his plot. Ben reunites with Rook, Rad, Hobble, and Scout when suddenly they are attacked by the brainwashed Anur Transyl citizens. Lord Transyl, Zs'Skayr, Crüjo, Kuphulu, and Viktor appear, and Transyl shoots Corrupturas at Rad, Rook, Scout, and Hobble. Rook, Rad, and Scout get brainwashed whereas Hobble remains unaffected and states that it is because of the mucus-covered skin of his species.

Ben scans Lord Transyl and transforms into a new alien, Whampire, a Vladat. He then shoots Corrupturas at Crüjo, Kuphulu, and Viktor. He, along with Hobble, Viktor, Crüjo, and Kuphulu, escape. Whampire then forces Viktor to tell him where the castle of Zs'Skayr is. Meanwhile at Zs'Skayr's castle, Zs'Skayr reveals that his true plan is to use the DNA of Lord Transyl to revive all the Vladats so that he could rule the universe. But suddenly the walls burst, and the Lovely Duck crashes into one of the walls. Whampire, Viktor, Crüjo, Hobble, and Kuphulu battle Transyl, Zs'Skayr, Rook, Scout, and Rad. Whampire is captured by Lord Transyl, who tries to hypnotize him, but to no avail.

The Omnitrix times out and Viktor, Crüjo, and Kuphulu are freed from Whampire's Corrupturas. Ben calls Hobble, but he is nowhere to be seen. Zs'Skayr orders Viktor to hold Ben still so that Lord Transyl can shoot a Corruptura at him, but Viktor betrays Zs'Skayr. Hobble starts firing beams from the Lovely Duck and destroys the machine which Zs'Skayr was going to use to revive the Vladats. Lord Transyl captures Ben, but he transforms into Atomix and creates "Fusion Cuisine," a light ball which kills Zs'Skayr and injures Lord Transyl, leading to everyone being freed from his Corrupturas. Atomix leaves the light ball in the castle so that if Zs'Skayr returns, he won't be able to get in. Viktor then takes Transyl and tells Rook that he would put him somewhere safe.

The episode ends with the Lovely Duck leaving the Anur System, and Viktor imprisoning Lord Transyl in a coffin-like containment unit in orbit right in front of the Anur System's sun.
