Universe Sigma

Universe Delta is the "family" universe; the most common deviation is the addition of one or more brand-new Rangers, almost exclusively relatives of the originals. A surprising number of these siblings belong to families whose Prime counterparts could not logically have more members, such as the Mitchells or the Corbetts. The theme continues even with the villains, who tend to be clans or nuclear families.

This universe is primarily explored in the works of Pink Lightspeed Ranger.
