Unlike the Green Rings of the Corps which operate by channeling pure willpower, these rings which are forged on Qward channel pure fear. Several versions of these rings have been created, but recently they have become the primary weapon of the Sinestro Corps, seeking out individuals to battle the Green Lantern Corps who have the ability to instill great fear.

Abilities of the Rings

The Ring is a source of limitless power, and thus there is no theoretical limit to what it can do, but here are some abilities it has been shown to have.

Artificial Intelligence:

Every ring has a connection to the Main Battery on Qward, which taps into Parallax. It acts as an "on-board computer," telling the wearer what they need to know. It can either respond out loud, or silently directly to the wearer's mind. The AI contains a large database of information that may be crucial to a "Sinestro's" success. The ring also translates nearly every language to and from the wearer, which is why the Corps can communicate with each other. When the bearer of a Sinestro Corps ring dies, the ring will seek out a suitable replacement for their sector, someone capable of instilling great fear.

Communicator:

The ring can act as a personal communicator between Sinestro Corps members.

Costumes:

The wearer of the ring may create a Sinestro Corps uniform.

Energy Beams, Bubbles, Force-Fields, and Blasts:

The rings can also project beams, form protective bubbles and force fields, and fire destructive blasts.

Energy Constructs:

The rings can construct anything the wearer can imagine from hard-light energy, as long as they are willing to make it. The more determined the wearer is, the more complex and intricate these things can be. The constructs can even be so complex as to form working machines, computers, and even people.

Flight:

The ring allows the wearer to fly in atmosphere or in space, and can achieve incredible speeds, moving from planet to planet in a matter of hours.

Mind Control:

The wearer of the Ring can use it to plant post hypnotic commands or control a person.

Mirages:

The Ring can create mirages/illusions. This would often be used to create images of monters or other horrific creatures or tableus.

Phasing:

The ring allows the user to go through walls.

Probing:

The ring can probe the Lantern's or another person's mind, allowing him to uncover memories or the person's thoughts, often to use them against to instill great fear.

Radiation

Besides light based radiation used to create the energy constructs associated with a Sinestro Corps member or a Green Lantern, the ring can simulate various forms of radiation. One example of this is the ability to simulate the radiation of Red solar radiation, which stunts or removes the powers of Kryptonians and Daxamites.

Recharging

The rings need to be recharged by means of a Power Battery. Other large sources of power may be used to recharge a power ring, however effectiveness may vary. The internal power source of a Manhunter Android is, in effect, the same as a power battery, and can be used to recharge a power ring. As a member of the Sinestro Corps recharges their ring, they generally quote the Sinestro Corps oath:

*“In blackest day, in brightest night,

Beware your fears made into light

Let those who try to stop what's right,

Burn like his power... Sinestro's might!”*
