The One Earth Government is similar to mine on Korugar, an alliance was logical, so, for now, I tolerate humans, even Hal Jordan (Main Universe Hal Jordan: So my doppelganger has joined your side) As did all who wished to live.

Powers and Abilities
Sinestro is often hailed as the "Greatest Lantern of All", possessing the willpower and ability to wield any ring of power to devastating effect, making him one of the most powerful ring bearers ever seen. . Although he was once a user of the green light of willpower, after his expulsion from the Green Lantern Corps, Sinestro harnessed the yellow light of fear and has mastered the power of fear for himself. Like a Green Lantern ring, a yellow Qwardian ring is capable of creating any construction formed by the yellow light of fear, limited only by the wearer's imagination. He is also granted the same natural benefits, including a barrier around the wearer's body, flight, travel at the speed of light, superhuman strength, and the ability to survive and speak in space.
Sinestro's builds are more alien in design and reflect his dominant personality, while being more powerful than an average Green Lantern. Sinestro primarily creates energy explosives, ranging from small orbs to creating small meteorites for increased damage. Sinestro favors bladed construction weapons, ranging from swords to an ax for direct attacks, and along with playing on the fear of his enemies, Sinestro will often create constructions in the form of spider limbs to emerge from his back to impale them, with said limbs even acting as projectiles. Sinestro also uses shackles and other binding constructs to restrict his opponent's movements, leaving them exposed for attack. Sinestro's control over his buildings is so precise that he is capable of creating portals to teleport, a feat most other power ring bearers consider impossible.
