With the Green Lantern Corps restarted with the return of Hal Jordan, Sinestro has founded the Sinestro Corps and has been been actively recruiting members, offering yellow power rings and a role in the Corps to those who can "instill great fear". Members of the Corps are immediately taken to Qward to "...be subjected to psychological and physical reconditioning". The Sinestro Corps works in sectors, much like the GLC. Qward now has a huge yellow "Central Battery" on it, like the one used on Oa.
Geoff Johns, in an interview, revealed that the Sinestro Corps is a mirror organisation to the GLC and it will have "its own Oa-type planet, its own Guardians, [and] its own oath."
Arkillo, a large and muscular vicious alien is enslaving all the Qwardian Weaponeers and forcing them to continuously build new yellow rings, programmed to breach the barrier between anti-matter and matter universe and find and recruit new ring-wielders. Arkillo also serves as the Sinestro Corps' drill sergeant, similar to Kilowog's role in the GLC.
Known members, other than the Corps' namesake and Arkillo, include Karu-Sil, raised by animals; Despotellis, a sentient virus capable of attacking Lanterns from the inside; Bedovian, the sniper of the Corps, capable of taking out a target from three sectors away while living off of the fungus growing on his "hermit crab" like shell. Previews indicate that Hank Henshaw, the Cyborg Superman, will join the Sinestro Corps. Ethan van Sciver has also stated that there will be a 'Frankenstein'-inspired member who is two aliens cut in half and sewn together, each one bearing a power ring, so that they are two bodies acting as one.
Recently, the Sinestro Corps attempted to recruit Batman, known even to some alien races for his great formidability and ability of instilling great fear in others. However, Batman's willpower combined with his previous brief exposure to a power ring allowed him to reject the yellow ring before it took him to be properly trained and molded into one of Sinestro's warriors. The yellow ring then sought a replacement and selected Amon Sur, the disgruntled son of Abin Sur, who was on Earth and attempting to steal Hal Jordan's ring.
