As a domain expert in comic book lore, I can tell you that the Green Lantern, a character from the DC Comics universe, has a few notable weaknesses. The most famous is the limitation of his power ring: it must be recharged regularly at the Central Power Battery on the planet Oa, and it is rendered ineffective against the color yellow, which is the representation of the emotion of fear in the emotional spectrum that the ring uses to create energy constructs.

The Green Lantern's power is also tied to the willpower of the wielder. If the Green Lantern is under extreme stress or experiencing fear, it can affect the ring's performance. Additionally, the ring's power is fueled by the user's own life force, which means that overuse can lead to exhaustion or even death.
