Viktoria debuted in Rad Monster Party. She found Ben sitting alone on a park bench and gave him a flower, however before the exchange could continue further they were disturbed by a crowd of angry Transylians, Ectonurites, Loboans and Thep Khufans so Ben was forced to flee and inadvertedly pushed Viktoria into the park pond as he did so, much to the latter's chagrin. Later on, she and the other citizens formed an angry mob around Ben and his team for harming Zs'Skayr, Viktor and Crüjo.
In Charmed, I'm Sure she develops a crush on Ben when he has acne from Swampfire's new transformation. She follows Ben around. In Zs'Skayr's Castle she asks Ben what his favorite food and color is. When he's fighting the pumpkins again she says "Viktoria Tennyson". When Ben goes back to normal, his spots have disappeared and her crush on Ben is gone. She goes back to hating him and asks "What did I ever see in you?".
Ben 10: Omniverse
- According to herself, Viktoria's favorite color is slimy green and her favorite food is gloppy.
- The scene with Ben and Viktoria in Rad Monster Party is similar to a scene from the 1932 film version of Frankenstein.
- In it a young, and rather naive, girl approaches the Frankenstein monster trying to befriend him, and gets thrown into a lake by the monster when he is attacked by a mob.
