Fan Casting Sunny Tennyson in Ben 10: Beginnings

Unlike in the prime universe where Sunny is another one of Ben’s cousins, she is instead Ben’s older sister, much like how Gwen has Ken as her older brother. Although Sunny acts very much like a typical teenage girl compared to her superpowered little brother, this normalcy makes her the heart and soul of Team Ben that keeps everyone else grounded. Although she and Ben often get on each other’s nerves, Sunny would do anything for him. And while she doesn’t have Ben’s alien forms, Max’s years of experience as a Plumber, Kevin’s abnormally superhuman strength, or Gwen’s intelligence and creative thinking, Sunny is still a pretty capable fighter through mixing her years of ballet, judo, gymnastics, yoga, and kickboxing training.
