The Milky Way is the galaxy in which Earth's Solar System exists in. Most episodes take place in this galaxy, and is the galaxy Ben's Team lives in. The nearest galaxy to the Milky Way is the Andromeda Galaxy.


The Milky Way is a spiral galaxy with Earth located on the Orion-Cygnus Arm.

  • A common practice in this galaxy for denoting property is including its creator's DNA signature, similar to the practice of autographing on Earth. This signature takes the form of several dots, and can be used to track the unique DNA composition of that creator across the galaxy.[8]
  • At one point in its history, Mars was called 'the Popcorn Planet' by Decka's Species, who used to visit the planet. They turned it into the red planet seen today, after one or more members of their species accidentally ingested meat.[9]
  • Due to it being the galaxy in which the Omnitrix was created, the vast majority of the Codon Stream's DNA samples, and thus the Omnitrix's potential transformations, come from this galaxy.
  • Celestialsapiens are born in the Forge of Creation, but some live in the Milky Way Galaxy.[DM 1]
