invades Warworld. Sinestro orders his Corps to stop intervening in his personal fight against Hal and confronts his former pupil face to face. During the battle, Sinestro discovers too late that his powers have decreased due to Soranik rescuing the people that were used to power the Fear Engine. Hal then uses his energies as a living construct to incinerate the Fear Warlord and destroys Warworld, apparently sacrificing himself and killing Sinestro in the process. Later, it is revealed that Sinestro survived from the attack, is critically injured and that he and Lyssa Drak were teleported to Qward. The Green Lantern and Sinestro Corps now under Soranik Natu form an alliance against the encroaching Dark Multiverse. Sinestro initially plans to cooperate but is met at the Source Wall by Lex Luthor, who invites Sinestro to Earth to join his Legion of Doom. Attracted by the promise of the "Invisible Emotional Spectrum", a source of power Sinestro became aware of in his youth just before joining the Green Lanterns, Sinestro abandons the Corps and travels to Earth. Reverting to his original Silver Age costume, and wielding the power of the Ultraviolet Corps rather than his Qwardian power ring, he successfully brainwashes half the planet and begins to bring the black sun Umbrax, source of the Invisible Spectrum, into the universe. After the plan is foiled, he remains an ally of Luthor. Powers and abilities Sinestro wields a yellow power ring that is functionally similar to those of the Green Lanterns, granting him flight, the ability to survive in any environment and the ability to create constructs of any shape and size. The ring must be regularly recharged with the aid of a power battery shaped like a lantern. Unlike Hal Jordan and most Green Lanterns, Sinestro wears his ring on his left hand. As a host whose body reined in and mastered the Emotional Embodiment of Fear, Sinestro now acts as the host as well as containment vessel for the emotional entity of his Corps; Parallax gives him unprecedented power both physical and metaphysical in nature. Like previous hosts before him, Sinestro has vast reality-altering abilities, as well as a greatly amplified ring. Physically, the Master of Fear gains a dynamism boost as well, putting him on par with some of DC's strongest characters such as Superman or most notably Black Adam, shown when both he and Adam moved Earth's moon
