Recruitment drive
Arkillo, a large and muscular vicious alien, is enslaving all the Qwardian Weaponers and forcing them to continuously build new yellow rings which are programmed to breach the barrier between the antimatter and matter universes to find and recruit new ring-wielders. Arkillo also serves as the Sinestro Corps' drill sergeant, similar to Kilowog's role in the GLC.
