Universe Sigma

Universe Sigma 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.

Following an attempt by the Gatekeeper of the Prime Reality to rewrite the multiverse, this reality became only the second to ever have advance knowledge of the threat posed by Kalask. It was also forewarned of the coming of Venjix, but still fell several years later, presumably involving the deaths of all or most of the previous Rangers in their attempt to stop the virus.

Operation Overdrive and Jungle Fury both occur in 2007 in this universe, with Venjix launching its attack in 2008. RPM was activated in 2011, with Samurai following in 2012.

Sigma appears to be somewhat unstable, with elements as minor as hair color or as major as a whole new person changing apparently at random. The cause is not yet known, though the Akra may have something to do with it.
