The Galaxy is the gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The majority of galaxies are gravitationally organized into groups, clusters, and superclusters. Records have proved evidence of number of galaxies in the observable universe range from 200 billion (2×1011), to 2 trillion (2×1012) or more, containing more stars than all the grains of sand on planet Earth. Most of the galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3000 to 300,000 light years) and separated by distances on the order of millions of parsecs (or megaparsecs). For example, the Milky Way has a diameter of at least 30,000 parsecs (100,000 LY) and is separated from the Andromeda Galaxy, its nearest large neighbor, by 780,000 parsecs (2.5 million LY). he largest structure of galaxies yet recognised is a cluster of superclusters that has been named Laniakea, which contains the Virgo supercluster.
Additionaly, the Galaxy appears as one of the main setting areas of the villain tournaments context, usually featured on Space Arcs storylines, recounting about events, political changes, and creation of civil wars, against minorites or majorites of any kind, at space. It also appears as one of the royal battle sceneries, during a Space Arc of any villain tournament, where it is threatened by various alien forces.
