Osmos V was the supposed home planet of the Osmosians.
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 Team that he intended to take them to Osmos V.
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.
