Trivia

 * 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 referance to Osmosians and their powers.
 * In Ultimate Aggregor, is confirmed that Aggregor lives on Osmos V.
 * According to Dwayne, Osmos V is the fifth planet from it's sun, Osmos.
 * As Aggregor was traveling from Aldabra to Osmos V, they passed Earth, this might mean Osmos V is futher away from Aldabra then Earth.
