Scarecrow, as Yellow Lantern, used the fear energy of his Sinestro Corps ring to terrify innocent people into committing violent crimes, an upgrade on his infamous ability to terrorize Gotham with his fear gas. However, without these things, Scarecrow is no longer terrifying.
The Sinestro Corps, occasionally known as the Yellow Lantern Corps, is a supervillainous group and analog to the Green Lantern Corps in the DC Universe. They are led by Sinestro, and derive power from the emotional electromagnetic spectrum of fear.
Yellow is the color of fear. Join the original Yellow Lantern — Sinestro — if you are driven by fear, inflicting it upon others, and letting the stuff determine your choices in life. Because in many ways, fear consumes Yellow Lanterns.
The Yellow Lanterns have been written as villains, with the main arch nemesis of the famous Hal Jordan spearheading their campaign against the universe.
It's the effect his costume and his reputation have on the criminals of Gotham City. However, because of his powerful will and because he had also been previously exposed to a Green Lantern ring, the Yellow power ring quickly left and chose to seek out another subject instead.
Unfortunately, Hal Jordan turned out to be more than a match for Sinestro. The two of them fought with their power rings until it came down to a brawl with bare fists on Oa. The fight came down to Hal getting Sinestro in a headlock and snapping his neck.
Kyle Rayner was also chosen as the sole member of the White Lantern Corps and trained vigorously to master the power of life itself. There is no doubt that Kyle Rayner is the most powerful of all lanterns, green or otherwise.
Rainbow Lanterns are beings of pure energy, encapsulated within a crystalline form that refracts light in all directions, creating a mesmerizing rainbow aura.
However, fixing the Green Lantern Corps' weakness to yellow was a little more complex. During the Green Lantern's Rebirth era under Geoff Johns, it was revealed that the "Yellow Impurity" was the result of the fear entity known as Parallax being trapped within the Central Power Battery, the rings' source of power.
First the greatest of the Green Lanterns and then their greatest enemy, Sinestro remains one of the DC Universe's most enduring antagonists. After becoming a Lantern to further instill order over the galaxy, Thaal Sinestro put his homeworld of Korugar under his own totalitarian control.
Once upon a time, Green Lantern power rings had a weakness to the color yellow. They couldn't affect anything that was yellow in color. That at the time was explained as a contaminant in the Central Power Battery that powers all the Power Batteries, and in turn power the power rings.
The Joker is widely regarded as one of the best comic book villains of all time, and in DC Comics' sprawling multiverse, a version of him exists that can wield the immense power of a Yellow Lantern; it's just too bad his powers — and his appearance as a Lantern overall — is one of the biggest letdowns in this new ...
On top of that, his wife was killed by the Manhunters, who were the predecessors to the Green Lanterns and were created by the guardians. This drives him mad and he becomes a tyrannical dictator trying to re-establish order to save his people by any means necessary.
He's powerful but not invincible, and there are ways to stop him. Hal Jordan, on the other hand, did not need any of these means to beat Superman. Instead, he uses the pure strength of the Green Lantern Corps, proving that a Green Lantern alone is powerful enough to defeat Superman.
The series features Cyborg Superman, Batman as a Green Lantern, Sinestro and Star Sapphire, all from Geoff Johns' historic run on GREEN LANTERN and featured prominently in the popular "Sinestro Corps War" story arc!
Even being killed by Darkseid can't keep DC's Green Lantern down - returning from the dead with more power than any Lantern before her! If anyone thought Green Lantern would let death stop her, they were sadly mistaken.
The Gray Lantern Corps is one of the Lantern Corps. The Gray Lanterns draw their power from their members' absolute apathy. As such, only members of Hattar's species can qualify for being Grey Lanterns.
The storylines "Sinestro Corps War" and "Blackest Night" introduce the rest of the spectrum, along with its emotions, corps and rings: red (rage), orange (greed), yellow (fear), green (willpower), blue (hope), indigo (compassion), violet (love), black (death), and white (life).
The Star Sapphire Corps is one of the ten Lantern Corps that draw power from the Emotional Electromagnetic Spectrum. The original was the Green Lantern Corps, and the Star Sapphires have usually been allies to the super-hero Green Lantern. Their color is "violet" and their power rings are charged by the emotion "love."
It is more than a desire for revenge against the Green Lantern Corps that has caused Sinestro to especially hate and strike at Hal Jordan. It is far more personal. Jordan was not corrupted by the ring as Sinestro was. Jordan was hailed as the greatest Green Lantern of them all.
As he began his rise to power, Sinestro and his wife Arin Sur (who is the sister of Abin Sur) began arguing about what he was doing. That, coupled with the numerous threats that were made against Sinestro and his family, caused his wife to leave with Soranik.
Sinestro is surely aware of the Kryptonian weakness to k-radiation, and he's more than willing to use lethal force. If a power ring can generate k-radiation then Sinestro will win easily.
