The red power ring has also displayed a number of weaknesses as well.

Those who face a Red Lantern already in a state of anger are even more vulnerable to a red power ring's attack, as their anger only feeds the attack and increases its destructive power. A Red Lantern can detect the rage in the heart of others and, by connection, the blood that pumps that rage. The Red Lantern ring is unique in that the user can manipulate its base of power, rage. Though most red ring wielders are little more than beasts driven by rage, individuals with strong willpower are able to manipulate the energy to create constructs. To date, Mera is the only Red Lantern who was freed this way. Also, if the heart of the wearer fills with love, which is the opposite emotion to rage in the Emotional Spectrum, the rage gets compromised and the connection with the ring breaks, instantly destroying the ring, but the light of a Blue Lantern is still needed to heal the former Red Lantern, because his/her heart goes into cardiac arrest by the lack of blood.

The combined powers of blue and green rings can destroy a red ring. However, a Blue Lantern's ring can reverse this process, freeing the wearer from the ring. As a result, removing a Red Lantern's ring will result in the wearer's death. Since the Red Ring completely takes over the circulatory processes of the wearer, removing the heart of a Red Lantern only temporarily incapacitates them.ДЄ red power ring operates by expelling the blood of the wearer, replacing it with red light. The Red Rings' blood is one of the few known substances that can destroy a Black Lantern's corpse faster than even they can regenerate. The blood can melt through the constructs of other ring wielders, penetrate their personal force fields (sometimes burning them to death in the process), and corrupt their rings, depleting their energy at an accelerated rate. The blood has the effect of bursting into flames of rage the flames are so potent that they will burn even in space. The user's blood is replaced by a form of corrosive, rage-energized blood. The power ring fires blasts of rage energy. Like other power rings, the ring covers the user in a protective aura which shields them from harm and enables flight, and can create 'Hard Light' constructs.

Red Lanterns use red power rings, fueled by the rage of their users and those around them.
