Who is Green Lantern?

The Green Lantern refers to a number of DC superheroes who fight
evil using the powers that come to them with the aid of rings. They are the
members of the Green Lantern Corps who were once a group of 3,600 members. They
acted as the Guardians of the Universe by performing the role of an
intergalactic police force.

The ring is controlled by willpower and its abilities have
never been properly defined by the creators. Some things that are known are that
all of its effects emit a green light, the wearers can travel at superfast
speed. However, it does not possess the power of automatic healing.

The ring’s power is directly proportional to the willpower
of the person wearing it which means that the power of each Green Lantern
varies greatly.
