10 Most Powerful Characters Killed By Hal Jordan's Green Lantern

The New 52 storyline Wrath of the First Lantern was successful in further expanding Green Lantern lore as well as introducing the villainous Volthoom, the first being to ever wield a Power Ring. Born 1000 years into the future of Earth-15, Volthoom and his mother were scientists who were studying the Emotional Electromagnetic Spectrum (the force that powers all Lantern Corps).

After making a handful of scientific breakthroughs with the Spectrum, Volthoom's world was attacked and this forced him to travel the Multiverse before landing on the main DC universe billions of years into its past. Here, he encountered the Guardians of the Universe and created his own Power Ring. Unfortunately, the Spectrum drove him insane and this forced the Guardians to imprison him.

The present day saw the Guardians attempt to create a new interstellar force by using Volthoom's energies to power it, but this failed and led to the escape of Volthoom. The First Lantern then proceeded to attack all the Corps in an attempt of securing the universe in order to rewrite the entire universe.

Fortunately, Hal (who was at the time a Black Lantern) released the Black Lantern entity Nekron in an attempt to stop Volthoom's machinations. This act was successful as the deathly being slaughtered a weakened Volthoom.
