Many Happy Returns

Many Happy Returns is the twelfth episode of Ben 10: Omniverse.

Plot
The episode begins with a fire raging in a building. A firefighter saves a man, but his daughter Madison is still inside. Ben appears and tries to transform into XLR8 but turns into Rath instead. He goes inside and rescues Madison, but she dropped her doll. Rath goes back inside, but is about to get knocked off, when Gwen saves him with a mana shield. Rath, Gwen and Kevin then exit the building, and gave Madison her doll. They then go out for smoothies.

Suddenly, a ship attacks them, and Rook saves them. They drive away in the Proto-TRUK, which turns into a jet. Ben uses Bloxx to stop it. Kevin then tells Ben that he needs to hide. Ben tries to hide him in Undertown, when the ship returns. Princess Looma Red Wind comes out, strangling Argit. Looma attacks them, and Ben holds her off as Terraspin. Looma defeats him, and attacks Kevin. They escape into the sewers, where Kevin tells them why the Princess is hunting him. When he worked with Argit, he beat Looma in a fight and got an engine for his car, but he had to marry Looma in addition. Kevin escaped her clutches, and she has been hunting him down since. Looma returns again, and Ben turns into XLR8 and attacks her. Looma escapes with Kevin and XLR8 chasing after her. Gwen and Rook exit the sewers. Above ground, they find Kevin, and XLR8 is receiving a serious beating. Gwen attacks her in her Anodite form.

Then, Gar Red Wind comes. Kevin is about to marry her when Ben challenges Looma to a battle. He changes into Crashhopper. Looma is defeating him when Ben tries to turn into Cannonbolt, but instead gets Clockwork. Looma beats him again when he turns into Shocksquatch. She still defeats him and he turns into Four Arms. Kevin thinks he has now got a chance to win, but Rook says that female Tetramands are traditionally stronger than males. But, Four Arms defeats her, and it is revealed that female Tetramands marry the ones that beat them in battle. Kevin and Gwen leave, and Looma says she'll be back in three years. Ben mutters that Kevin is "so dead" as Rook looks back to see Argit sound asleep.
