Bloom-Out is Marluxia's Limit Break. It allows him to charge attacks that cause him to swing his scythe multiple times across a large area. Upon each attempted attack a black ring will appear and grow outward; attacking during this period will yield a simple, weak spinning strike. When the ring reaches its maximum size, it will flash pink before disappearing; if Marluxia unleashes the attack while the ring is pink, the resulting attack will be much more powerful, having him spin twice accompanied by cherry blossoms. During the Final Limit, Marluxia's swings are faster and cover a larger area. A perfectly-timed attack during the Final Limit causes him to leap before revolving his scythe three times around himself, followed by the release of large, crescent-shaped projectiles to indicate maximum range.
