The Solar Bomb

The Solar Bomb is the single most powerful weapon in the Universe.

Little is remembered about how its internal systems function, as there were only seven ever created, but what is known is what it does; it releases colossal amounts of energy through the annhialation of Singularium, causing Material Space and Subspace to connect at a single point in space and time, unleashing enough energy, that its blast is comparible to the size of the Galaxy. A method of improving the devastating power of a Solar Bomb was formulated, which predicted that the Singularium's energy would quadruple, but it was incapable of being tested, as it would require the Singularium to be plunged into Subspace.

Since Subspace is the polar opposite of the Mirror Dimension, Subspace completely eliminates any and all traces of any indiginous to the Mirror Dimension. This is how the the First Mirror War ended, when five Solar Bombs were used to destroy the Super Mirrors that were letting the Mirror Dimension pour forth. A single Super Mirror remained dormant, which led to the Second and Third Mirror Wars.
