A psycommu-enabled unique prototype unit by BESPA (Zanscare Imperial Army) that was fielded near the end of the Zanscare War. The Zanneck's mega beam cannon can hit targets on Earth from high in the atmosphere, or across long distances in space. The blast from this beam cannon could only be deflected by the LM314V21 V2 Gundam's mega beam shield or its wings of light.
To compensate for the mobile suit's low mobility when using its beam cannon, a large flight support system known as Zanneck Base was developed for its use. The Zanneck's cockpit has two seats for a pilot and a gunner.
