Sinestro Corps: Mongul (DC Universe, Arkillo wave)
The son of an infamous galactic conqueror, Mongul is driven by a burning desire to surpass his father's murderous achievements. Mongul broke into the Justice League Watchtower only to be turned back. Next, he used the hallucination-inducing Black Mercy plant against Green Lantern, but it could not overcome Green Lantern's indomitable will. After that, Mongul's main enemy became the Green Lantern Corps.
Includes the right arm of Arkillo.
