The Doomsday Device[1] is an object that appears in the Sonic Boom series. It is a weapon in the evil scientist community that is capable of destroying the entire world.[1]

The Doomsday Device is a rather large machine. It has a dark gray egg-shaped center that is held up by a white frame. This frame stands on four striped legs that has wheels for feet. Its frame also has a black sphere and handle bars on two of its opposing sides. On top of the device are two rotatable white prongs with red bulbs and a black barrel for charging its energies.

Features and abilities

The Doomsday Device is perhaps the most destructive weapon seen to date in the Sonic Boom World. As per its purpose, the device can charge up and fire a sphere of powerful and unstable energies set at certain frequencies which can seemingly erase matter over a radius encompassing an entire planet, effectively destroying a planet. The device comes equipped with a countdown and cannot be deactivated once it is initiated due to the lack of an off switch.[1]

If a similar machine releases energies vibrating at opposite frequencies at the same as the other Doomsday Device, the two energies will cancel each other out without any ill effects. However, if there is even the slightest power discrepancy between those energies, then the resulting effect will create a reality-destroying black hole.[1]


TV series

Season one

Dave finds the Doomsday Device, from "Double Doomsday".

An unfinished Doomsday Device of Dr. Eggman's that only lacked a proper power supply was kept in Eggman's lair. Eggman would introduce this device to his new intern, Dave. In an attempt to prove himself fit to be evil however, Dave sealed himself in another room with the Doomsday Device and activated it. Not wanting to be outdone, Dr. Eggman created another Doomsday Device to compete with Dave's. Picking up the devices' energies, Sonic and Tails went to the lair and tricked Eggman and Dave into calibrating their Doomsday Devices into releasing energies at opposite frequencies in hopes that they would cancel each other out when fired (since turning them off was not possible). However, a small difference in power caused the two Doomsday Devices to create a black hole instead, which Sonic closed with the Reverse Polarizer.[1]

Season two

When Dr. Eggman was in need of money, Orbot suggested he sold his lair's Doomsday Device, but Eggman turned that idea down. Said device was later activated when a Scorpion Bot got knocked into it during a battle between Eggman and Team Sonic. Thankfully, instead of destroying the world, the device only blew up Eggman's lair.[2] During his semester some time after, Professor Kingsford had his class construct a rudimentary Doomsday Device as a class project. However, because Eggman did not get a rubber gasket, the device never became more than a "glorified paperweight".[3]
