When Eon causes 11-year old Ben swap minds with teen Ben, it's up to Gwen, Rook, and Professor Paradox to set things straight.
Tropes in this episode
- Foreshadowing: Twice by Ben 10,000:
- The temporal beasts may probably be the Time Beast, who will debut later in "Let's Do the Time War Again".
- Ben 10,000 mentions Maltruant, who would later be the last antagonist faced in Omniverse.
- "Freaky Friday" Flip: Eon accidentally swaps the consciousnesses of the Bens.
- The Greatest Story Never Told: In the end, this episode’s events Cosmic Retcon themselves out of existence.
- Villainous Breakdown: Eon suffers from this. When the time portals he creates begin to damage the timestream, he loses his cool and accuses Paradox of having tricked him. He then decides that if he can't rule the cosmos, he'll destroy it.
- Voices Are Mental: When the two Bens swap bodies they still have their regular voices. This is lampshaded when the 16-year old Ben, now in his 11-year old body, meets up with the Gwen and Max from the past and they note how he sounds different now, leading them to believe his time-travel story.
- We Want Our Jerk Back!: A variation happens with the 11-year old Gwen. She is so used to dealing with Ben being immature and insulting her that Ben suddenly being so mature and nice to her, due to having his teenager mind, freaks her out and makes her think he's up to something. She even tells him to stop being so nice to her, and snapping at him each time he apologizes.
