Notes[]
- ↑ Ben 10,000 and Kai were stated to have a daughter, named Gwendolyn,[pop-up 2][2][pop-up 3][3] who never appeared on-screen. When asked if Gwendolyn still existed in the Original Future Timeline as of Omniverse, Derrick J. Wyatt initially said she did not,[DJW 1] stating that he hated that she was named after Ben's cousin Gwen and decided to ignore her existence.[DJW 2] When made aware that Gwendolyn's existence was revealed via pop-up trivia years later, Derrick admitted that he did not know she existed, and was probably confused by the earlier question. He also explained that the reason she was never used in Omniverse is because the crew, who had studied the Original Series episodes for research, did not have access to the pop-ups. Therefore, they were not aware that Ben 10,000 had a daughter.[DJW 3]
