When the Time Stone becomes attached to Tony's arc reactor, it causes him to de-age and brings dangers from other eras, including dinosaurs, into present-day New York City.
- The premise of this episode was a small nod to both Iron Man: Armored Adventures (a series in which Tony Stark is a teenager), and "Teen Tony" (an alternate reality version of Stark who replaced the original one for a period of time).
- When the robots from the future detected Hulk, they refer to him as Maestro, a version of Hulk from an alternate future.
