The Mirror Dimension[1] is a location that appears in the Sonic Boom series. It is an alternate dimension existing parallel to that of the Sonic Boom World.


The Mirror Dimension is, as the name suggests, a mirror image of the Sonic Boom World. Physically, it is nearly identical to its counterpart except for some miniscule physical differences. The main difference is that its residents are polar opposites of their Sonic Boom World counterparts in terms of personality, though not necessarily in terms of alignment. For example, Team Sonic are still heroes fighting the villain Dr. Eggman, but in this dimension, Knuckles is an extremely wise and capable leader while Sonic is an utterly clumsy and childish oaf. In addition, Dave the Intern is a member of Team Sonic and highly intelligent.[1]

The existence of the Mirror Dimension has been theorized for years by Miles "Tails" Prower.[1]


TV series


Much like in the Sonic Boom World, the Team Sonic of this world has continuously fought against the villainous efforts of Dr. Eggman, except that they have fought under the leadership of their extremely intelligent and brave leader, Knuckles the Echidna.[1]

Season one

When Knuckles got sent to the Sonic Boom World by Octopus Bot during a battle between Team Sonic and Dr. Eggman, the Mirror Dimension was in danger of imploding from the eroding barrier between the dimensions caused by Knuckles' departure until the Tails from the Sonic Boom World sent him back. Once back there, he resumed his battle against Eggman with his teammates.[1]


Dr. Eggman wearing green is the only aesthetic difference from the Sonic Boom World.
