The Doomsday Device is a rather large machine. It has a dark grey 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 of all of Dr. Eggman's inventions to date. 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. The device comes equipped with a countdown and cannot be deactivated once it is initiated.
An unfinished Doomsday Device was kept in Eggman's Lair. This device would be activated by Dave the Intern in an attempt to prove himself evil. Not wanting to be outdone, Dr. Eggman created another Doomsday Device to compete with Dave's. Picking up the devices' energies, Sonic and Tails tricked Eggman and Dave into calibrating their Doomsday Devices 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.
