Warden is the last phase of combatuid evolution. Instead of merging bodies with its pilot, the combatuid is granted a share of its pilots soul and gaining self consciousness. A warden is a completely new form of a living creature since it posesses a soul. Wardens are able to self-reproduce through their orbs. An orb, once establishes a facility, creates a new orb and transforms its consciousness into it, seeking a fitting pilot to its soul through complete vibration. When a pilot is found, a new either combatuid or an eidolon is born, only to achieve the evolutional cycle all over again. Only 3 combatuids reach the Warden phase: Lexion, Reventon and Galand.

Galand eventually becomes the ancestor of all combatuids/eidolon in the Third Sun Epoch.
