Electrocage

The Electrocage is an object that appears in the Sonic Boom television series. It is a piece of technology invented by Dr. Eggman for imprisoning Team Sonic.

Description
The Electrocage is mainly a high-tech hover disc with a red projector on the bottom. When activated, it generates a number of unmovable orange energy rings below it in the shape of cylinder, forming a cage so impeccable than none of Team Sonic's members can escape it. However, the prisoner can still stick their limbs out between the energy rings. The entire device is controlled by a remote control.

History
The Electrocage was invented by Dr. Eggman as a means to capture Team Sonic. While in the Village, Eggman condescendingly demonstrated his Electrocage to Dave the Intern before he got knocked out. Dave then used the Electrocage to imprison Eggman in his house while he hijacked the doctor's forces, until Sonic arrived to free Eggman from the cage.
