“The greatest Green Lantern in history — who became the master of fear.”
Feeds on opponents' fear to generate yellow constructs. Specifically effective against Green Lantern energy.
More adept at breaking an opponent's will through fear than through physical combat.
Once the most skilled ring-wielder in Green Lantern history. All that expertise transfers directly to the yellow ring.
A perfectionist who began with good intentions and arrived at tyranny. He genuinely believed in order — which is why he never compromised on the means of enforcing it. He was Hal Jordan's mentor, but when his student rejected his philosophy, it became the root of every conflict that followed. The fact that he didn't start evil is what separates him from ordinary villains.
