Me thinks someone with the IQ to develop the device Amy had on her could only be of the following (and she might have snatched it from one of them): Bulma due to having merged the Dragon Ball World with ours long ago, Dexter, Jimmy Neutron, Professor Ludwig Von Drake (she might have found him as it might of taken place inside or outside of Toon Town), Tony Stark, Mr. Fantastic, Silas Stone, Cyborg's father, Dr. Tomoe aka Hotaru's father, Rick Sanchez from Rick and Morty, or she might have found Cameron and forced him to build it. That or she stole it from Wayne Tech. or Star Labs. Still, it might as well be an unsolved mystery. But, all's well that ends well. Amy's locked up for the rest of her life and that's the last we'll see of the TD losers.
