The limit is named for Uluru, also known as "Ayers Rock," a prominent, rust-red rock formation in Australia that serves as a famous landmark.
Ayers Rock is Lexaeus's Limit Break. It allows Lexaeus to charge his energy, indicated by a red aura around him, to perform powerful 180-degree swings, followed by shockwaves. The strength of each attack depends on the amount it was charged up for. During the Final Limit, Lexaeus' weapon becomes engulfed in rock before releasing each charged attack, increasing its strength and range.
