Not much is known about the Destructo-Tron 3000. However, it needed a recombobulator in order to counter-balance the discombobulation field in order to prevent the weapon from extirpating itself. It also needed a Chaos Emerald to function properly.
To build the Destructo-Tron 3000, Dr. Eggman stole Milan Ramada's limousine in order to use the experimental compartments from Ramada Refineries, Incorporated within it. As the weapon was nearly complete, it only needed a Chaos Emerald to function. Because Eggman failed to get the Emerald though, the weapon never saw any use.
