The Sphere of Fear is an object that appears in the Sonic Boom television series. It is a sphere-shaped cage, produced by Eggman Industries.


The Sphere of Fear is, as its name implies, a sphere-shaped object with a blue frame, yellow joints and a netting of smaller metal treads. The only entrance is a round hatch. The Sphere of Fear is unbendable, unbreakable and cannot be melted, making it virtually inescapable. Because of its shape, it allows speeders like Sonic to move inside it at unparalleled speeds.[1]


TV series


The Sphere of Fear was produced by Eggman Industries and put on sale by Dr. Eggman for six easy payments (plus handling and shipping).[1]

Season one

One customer who bought the Sphere of Fear was T.W. Barker who needed it to contain Sonic and keep him in his circus as a performer. When Barker convinced Team Sonic to fill in for his performers, he made the Sphere of Fear Sonic's performance equipment. After the show, Sonic was trapped inside the Sphere of Fear while his friends were trapped in cages. Though Sonic's attempts to escape failed, Tails came and broke the Sphere of Fear's footing, allowing Sonic to escape it and trap Barker inside it instead.[1]
