Ranks can only be given by the Dimension's Alpha. Ranks can be positive and negative. A positive Rank improves some of the Commander’s characteristics and a negative Rank reduces them. Each Rank is valid for 7 days as long as the Time Machine status does not change to Charging. After a Rank has been given to a Commander, it cannot be transferred or canceled. Information about an awarded Rank can be viewed in the Commander's Info window; the Rank is also indicated beside the relevant userpic.
