Kanjar Ro (Earth-5180)

"Why should I quit? This job gives me gifts, better than anything you can offer me!"

- - Kanjar Ro to Captain Marvel

Kanjar Ro is an interstellar Dhar pirate whom was recruited by Amon Sur to manipulate the Sentinels to frame John Stewart for a crime he did not commit so they could invade Oa and destroy the Green Lantern Corps. After being uncovered by Captain Marvel and Thor, he was imprisoned on Oa.

The Manhunter Plot
Kanjar Ro was hired by the rogue Ungaran Amon Sur to testify against John Stewart at the behest of the Sentinels on Ajuris, so they could be convinced the Green Lantern Corps became corrupted with their power.

Testimony
And so Kanjar did, arriving against Stewart at the planet in the presence of thousands of Sentinels and Green Lanterns, among them, the Guardians of the Universe. Ro falsely told the mechanical guardians about the destruction of a planet at the hands of John. The Sentinels became convinced this was true, and thus sentenced the Lantern to death. However, the Justice League members Captain Marvel and Thor decided to intervene, and the Sentinels decided to give them 4 hours to collect and give them proof of John's innocence.

Fight and Capture
Car-Ol and Thor then arrived at the planet, but noticed the star map presented by Kanjar Ro did not match, discovering it was all a lie. The pirate suddenly appeared with his ship, in an attempt to kill the heroes of Earth before they could reveal the truth to the Sentinels. He employed the use of holo-drones to create holographic copies of himself and fool the two heroes, but they were easily destroyed. He was beaten by Captain Marvel, who took him back to Ajuris alongside the God of Thunder in the hopes of proving Green Lantern was framed. Kanjar was then interrogated by the Sentinels, in an event which was cut short as soon as the metal soldiers were mysteriously deactivated.

Revelation and Arrest
They reactivated, but changed, and flew away from Ajuris, at the direction of Oa. John threatened Ro, who confessed he was hired by Amon Sur to create a ruse between the Green Lantern Corps so they would leave Oa, giving Amon an opportunity to destroy the Central Power Battery and destroy the Corps as vengeance for his father's death at the hands of Parallax.

After telling the truth, he was aprehended by Green Lantern Honor Guards and imprisioned on Oa to serve the rest of his life.
