My Justice League picks, 15th collage: 
Bizarro, recently brought to Mars by the Martian Manhunter, was transferred to the 
authority of the Green Lantern Corps, an intergalactic police force who enforces the 
laws of the Guardians of the Universe. They enforce their laws using weapons called 
power rings. 
 
A short time after taking Bizarro into custody, the corps detected an odd energy 
reading from the planet Earth. The energy field was identified as that of a Zamaron 
power ring. The corps immediately went to Earth to investigate, fearing that their 
enemies, the Zamarons, had infiltrated Earth. 
 
After investigating, they were relieved that the ring had been discovered by a mere 
human by the name of Lana Lang, who they later also learned was the leader of a 
vigilante group known as the 'Hand of Vengeance'. 
 
Eager to return to their respective home planets, yet sworn to obey the laws of the 
Guardians, the corps decided to find someone in their stead who could provide a 
balance for Lana Lang's newly discovered power ring. 
 
The Corps ultimately offered to offer the ring to Jordan Cross, the leader of the 
Justice League, but Jordan subsequently refused the ring. 
 
According to the laws of the Guardians they couldn't leave Earth without appointing 
someone to balance the power of the Zamaron ring. However, they also needed to 
return to Mars immediately in order to relieve the guard for Bizarro. They decided 
that they would relieve the guard, and then would return later to find another to take 
the ring. In just a few seconds they flew away, back to Mars, but no one ever saw 
them again. 
 
It's rumored that Bizarro was able to convince a Corps officer by the name of 
Sinestro to abandon his post, a decision that led to the deaths of two of his fellow 
officers and his commander as well.
