The Controllers expanded the Darkstar project after the collapse of the Green Lantern Corps Central Power Battery on Oa.

In the 2006 Omega Men and Mystery in Space miniseries, an organization called the Darkstars is active in the Vega system, serving as clergy and missionaries for Lady Styx.

Among the equipment stolen by prosecutor Kate Spencer when she becomes the eighth Manhunter is an exo-mantle which formerly belonged to an unnamed Darkstar.

As seen in Manhunter #32 (September 2008), the exo-mantle reacts adversely to a Reach scarab bonded to Blue Beetle Jaime Reyes.

It appears as if the Controllers programmed an instinctive hatred of the Reach into all exo-mantles, just like the Guardians of the Universe did with the Power Rings worn by the Green Lantern Corps.

The Controllers reveal themselves to be on the brink of extinction, and started kidnapping the Guardians of the Universe in order to use their DNA to create new conditions.

[7] Tomar-Tu later reveals to Hal Jordan that the mantles gained consciousness of their own and, after bonding with a suitable volunteer, it trapped all the Controllers in order to use their psionic powers to link all Darkstars' thoughts and use the cosmic energy inside their bodies to fuel their foundry.
