The Akhano'kali

The Akhano'kali (pronunciation: "ahkah-no-kah-lee") is a legendary synthetic beast designed and created by the Azeran as the proposed antithesis of the Keinoid. It is believed to have power to defeat anything in the physical universe, but its purpose in fighting both the Keinoid Beast and Zerahkeil are untested.

The Akhano'kali appears only once in the main series in the episode "Stellar Travelers" and is not slated to make any appearances in Mark of the Colossus.
