Bygone Island mirror dimension

The Bygone Island of the Mirror Dimension.

The Mirror Dimension is a location that appears in the Sonic Boom television series. It is an alternate dimension existing parallel to that of the Sonic Boom World. It is nearly identical to its counterpart except that the people there are polar opposites in terms of personality from their Sonic Boom World counterparts, though not necessarily in terms of alignment, and some miniscule physical differences. Its existence has been theorized for years by Miles "Tails" Prower.[1]


Much like in the Sonic Boom World, the Team Sonic of this world has continuously fought against the villainous efforts of Dr. Eggman. When Knuckles got sent to the Sonic Boom World though, 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.[1]


Green Eggman Boom

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