10 Worst Things To Ever Happen To Green Lantern

10. Hal Jordan's Girlfriend Becomes A Supervillain

Despite already boasting a deadly rogues gallery, Green Lantern Hal Jordan was introduced to another archenemy - his girlfriend.

First appearing alongside Hal Jordan in 1959, Carol Ferris was originally introduced as the ambitious test pilot's employer and eventual romantic interest.

Despite telling him that she didn't date her employees, Carol would go on to become Hal's on/off girlfriend throughout the comics. A main character of Green Lantern's sci-fi inspired run, Carol would take on a deadlier role - as a supervillain.

Possessed by an alien gem, Carol became Star Sapphire - the second Star Sapphire to appear in comics. With the original Star Sapphire menacing the Golden Age Flash, this super-powered star warrior was a dangerous threat to any hero.

With the gem possessing her, Carol became under the control of the alien Zamarons - a race of female warriors obsessed with the idea of proving women to be superior to men.

Using flight, increased strength and durability, and similar energy construct-based powers to the Green Lanterns, Star Sapphire became a formidable foe for the Emerald Warrior.

Over the years, fighting Carol took a toll on Hal's relationship with her. Wiping her memory after their battles, Hal would try to force the Zamarons to relinquish their possession. However, her villainous persona would continuously resurface to challenge Hal and provide him with an enemy he had two minds about defeating.
