What the Canon Says (Barely)#
The sum total of canonical description is direct: massive sea creatures. Beyond that, the record goes quiet. Were they named? Did they serve a specific function in the Matoran UniverseMatoran UniverseA civilization of biomechanical beings living inside a colossal robot, destroyed when Teridax seized control.'s early ecosystem? The surviving chronicles do not answer.

The Unanswered Questions#
What remains genuinely unclear is whether the Great Beings deliberately concealed details about them, or whether the first chroniclers simply lacked access to the earliest eras. Did the Great Beings create them for a specific purpose now lost to time? Do any still survive somewhere in the universe, waiting to be rediscovered? No surviving account answers these questions.
