Dome-pocalypse

The Dome-pocalypse, also known as the Village Fortifying Electromagnetic Protective Hemisphere, is an object that appears in the Sonic Boom television series. It is a device invented by Tails as a defense against Dr. Eggman.

Appearance
The Dome-pocalypse is a small yellow box with a black bottom and top, and handles on the side. On top is a smaller yellow box with an openable lid and two orange buttons on each side.

Features and abilities
Wen activated, the Dome-pocalypse projects a blue electromagnetic hemisphere force-field at the size of the Unnamed Village. This shield is durable enough to withstand the pressure from the Egg Tank's drill, and any energy beam's fired at it simply bounce off. However, the force-field does not extend underground, meaning one can simply tunnel under it.

Season two
The Dome-pocalypse was invented by Tails to protect the Unnamed Village from Dr. Eggman forever. While the device neutralized Eggman's aerial attacks (earning Tails lots of praise), Eggman would tunnel under its force-field and then bounce his Egg Tank's blasts off the force-field from the inside, causing untold damage to the Village. Grabbing the Dome-pocalypse, Knuckles pushed the force-field against the Egg Tank until Eggman was defeated and Tails could turn the device off.

Trivia

 * The Dome-pocalypse is apparently very dense as even Knuckles had trouble lifting it despite his super strength.
