# Energy Constructs: The ring can be used to fire blasts of colored energy or create weapons such as projectiles of them.
# Force-Field: The ring can create various forcefields of various sizes and shapes to protect the wearer and others around him or her. In space, a power ring creates a force-field around the wearer, protecting him/her/it from the hazards of the void, including filtration of stellar radiation and microscopic particulate matter which would ordinarily be fatal should the space debris strike the ring wielder at high speeds. An atmosphere appropriate to the ring wielder's biology is created inside the force-field, body temperature is maintained and waste products are removed. Gravitational stresses which could cause injury are stabilized for the ring wielder.
# Phasing: The Power Ring allows the wearer to pass through certain solid objects, such as walls. Which objects that are not penetrable are not known, but it may depend upon the strength of the wearer's mastery of fear and the density of the object's molecular structure.
# Environmental Playback: Upon request, the power ring can recreate a holographic environment based on data in its memory banks. The ring wielder can observe events in a ghostlike state, but the ring wielder cannot alter the outcome of the playback. All objects in the playback will appear in the full spectrum of colors, regardless of the wielder's level of expertise creating simulacrums. The power ring will automatically end the playback if outside interference warrants the ring wielder's undivided attention.
# Invisibility & Light Refraction: A ring wielder can render him/her/itself invisible by willing the ring to bend light waves around his/her/its form, as well as that of the power ring.
# Energy Twin: The power ring allows the wearer to create an "energy twin" of his/her/itself that can travel at far greater speeds than that of the ring wielder's physical form. While the energy twin is active the ring wielder remains motionless, his/her/its life force is needed to guide the energy twin. The energy twin can not alter its surroundings, and may only be perceived by another ring wielder as a yellow, ghostlike image. Any knowledge gained by the energy twin is transferred back to the ring wielder's physical form upon recontact with the body.
# Energy Absorption: The ring can absorb and store most other energies. Unlike the green lantern power rings a Qwardian power ring can replenish the normal store of energy the ring has. A ring that needs recharging but contained a store of electricity could only discharge that electricity, for example.
# Flight: By the manipulation of anti-gravitons and directed molecular movement, the ring allows the user to fly at incredible speeds. In atmosphere, a Sinestro Corpsmen has been known to fly as fast as Mach 10 in atmosphere by creating an aerodynamic envelope around his body. Towing others, usually within a bubble, his speed is limited to the twice the speed of sound or 1440 mph. In space, Sinestro Corpsman's speed can be significantly greater and has been known to approach 80% of lightspeed in normal space. Flight is possible at velocities exceeding light speed. In atmospheres, air friction is not a hindrance, since heat is either absorbed or reflected by the ring's field.
# Wormholes & Spacial Warps: The power ring grants its wearer access to wormholes in space, enabling the ring wielder to rapidly cut time and distance needed for transport. Black holes can be navigated by experienced ring wielders.
# Time Travel: Time travel is possible with the power ring, though the further forward in time a ring wielder travels, the more mastery of fear it takes.
# Limited Cellular Regeneration: This ring has a limited ability to heal physical injuries and this seems to be a feature held over from the previous incarnations of the ring. A Lantern Corpsman can use the ring to repair minor injuries in himself or others.
# Electromagnetic Scanning: The ring has a wide range of detection abilities based on the imagination of the user. If one can conceive of it, he can probably detect it. Magical effects like clairvoyance, seem to be beyond the scope of the ring. Most normal electromagnetic phenomena are within the range of the ring, including radio, television, infrared, ultraviolet, and high frequency band communications.
# Universal Translator: Keeping in mind the myriad of worlds, life forms, and cultures throughout the cosmos, it is understandable why Sinestro added a translation system to the power ring. The power ring can translate virtually any language in the universe, facilitating diplomatic encounters rather than violent confrontations.
# Material Alteration: A Lantern Corpsman's uniform is not made out of fabric. It is created by the Power Ring whenever the wearer wills to wear it. It automatically appears over the wearer's normal clothing, and vanishes when the wearer wills to return to their civilian attire. Most Sinestro Corpsmen wear similar uniforms that are programmed into the ring by default. However, each Sinestro Corpsman is able to adjust their uniform to fit their own needs, personalities and whims. The yellow parts of the wearer's uniform are usually very warm or hot to those who touch it, while the black parts are very cold.
# Ring Duplication: Most Power Rings are capable of automatically duplicating themselves. Each duplicate typically shares the qualities and capabilities of the original ring. While the thought of an unauthorized person getting a hold of a power ring and making duplicates for nefarious purposes, their ability to inflict damage is limited because each duplicate still requires to be recharged by a personal power battery.
# Emergency Beacon: A Lantern Corpsman in distress can use his/her/its power ring as an emergency beacon. The alert can be directed to a Lantern Corpsman's neighboring sector, or it can be a Corps-wide alert.
# Homing Beacon: A homing beacon in the power ring can lead one Sinestro Corpsman to another. The power ring can be ordered to disguise itself to elude power ring wielding trackers. Most often ring wielders will allow the beacon to signal their location to others.
# Mind Alteration: As the power ring relies on thought and will to operate, mind tampering is not impossible, the real difficulty lies in properly applying the power. There lies a risk of catastrophic damage to the mind should mistakes be made. A ring wielder can use the power ring to erase portions of an individual's memories.
# Security Protocol: The rings can be programmed. They are coded to the wearer to make them unusable if stolen.
# Preset Conditions: Commands can be stored in the ring to be executed at a later date, even if the bearer is not wearing the ring.
# Thought Relay: Otherwise known as a telepathic link.
