The Crystal Feelers (クリスタルフィーラー, Kurisutaru Fīrā?) are a boss in Chapter 12 of Dirge of Cerberus -Final Fantasy VII-. They do not have any kind of attacks or defense, but Omega Buds appear during the battle to harass the player. The Crystal Feelers can only be damaged by melee attacks, and even then only when they are open. The player must move around the battlefield until one of the Feelers opens long enough for them to destroy it. Once all the feelers are destroyed, the Omega Cocoon appears.
Omega (capital: Ω, lowercase: ω; Greek Ωμέγα) is the 24th and last letter of the Greek alphabet. It commonly represents the end or a limit of something, such as the concept of "alpha and omega".
