The Celestial Weapons are the ultimate armaments for each character in FFX, ignoring defense and dealing maximum damage. Obtaining and fully powering them up requires completing various challenging mini-games and side quests. For example, Tidus's Caladbolg requires winning the Chocobo Race at Remiem Temple, while Yuna's Nirvana involves capturing all fiends in the Calm Lands. Each weapon has a unique activation requirement and a specific crest and sigil to fully upgrade it.
