Osmos V was the supposed home planet of the Osmosians.


Ultimate Alien

Osmos V was first mentioned in Escape from Aggregor, Aggregor told Bivalvan, Andreas, Galapagus, P'andor and Ra'ad that he had built a machine on his home planet to let him absorb all of their powers and that they were heading there before the aliens escaped to Earth.

In Ultimate Aggregor, Osmos V was mentioned again by Aggregor when he was ready to leave Earth, he told his robots to make a jump to Osmos V. When Aggregor was about to absorb the aliens, he told Ben's Teamthat he intended to take them to Osmos V.


In The Rooters of All Evil, it was revealed that Osmos V was a fake planet, made up by Servantis.

Notable Inhabitants

  • Osmosians
    • Aggregor (formerly)


The name Osmos V comes from the word "osmosis", the process by which a solvent (e.g. water) diffuses from an area of a high concentration through a semi-permeable membrane into an area of low concentration. It is also the process by which cells absorb water and nutrients. This is a reference to Osmosians and their powers.


  • According to Dwayne:

    • Kevin has never been to Osmos V.
